2.10 Use Auto
Once the oscilloscope is properly connected and a valid signal is input, tap the Auto Set button to
quickly configure the oscilloscope to be the best display effects for the input signal.
Auto is divided into Auto Set and Auto Range. It is defaulted as Auto Set.6
Auto Set — Single-time auto, and each time press “Auto”, the screen displays “Auto” in the upper left corner.
The oscilloscope can automatically adjust the vertical scale, horizontal scale and trigger setting according to the
amplitude and frequency of signals, adjust the waveform to the appropriate size and display the input signal.
After adjustments, exit from the auto set, the “Auto” in the upper left corner disappears.
Channels may be automatically opened. Any channel greater or less than the threshold level can be opened or
closed automatically according to the set threshold level. The threshold level can be settable.
Source can be automatically triggered, and the triggered source channel can be automatically set to select priority
to the current signal or to the maximum signal.
Open the main menu. Tap “Auto” to open the auto set menu, including channel open/close setting, threshold
voltage setting and trigger source setting.
Figure 2-8 Open Auto Set
Automatic configuration includes: single channel and multiple channels; automatic adjustment of the horizontal
time base, vertical sensitivity and trigger level of signal; the oscilloscope waveform is inverted off, the bandwidth
limit sets to full bandwidth, it sets as DC coupling mode, the sampling mode is normal; the trigger type is set to
edge trigger and the trigger mode is automatic.
Note: The application of Auto Set requires that the frequency of measured signal is no less than 20Hz, the
duty ratio is greater than 1% and the amplitude is at least 2mVpp. If these parameter ranges are exceeded,
Auto Set will fail.
16
Figure 2-9 Auto Set Waveform
Auto Range - Continuously automatic, the oscilloscope continuously adjusts the vertical scale, horizontal time
base and trigger level in a real-time manner according to the magnitude and frequency of signal. It is defaulted
as off and needs to be opened in the menu. This function is mutually exclusive with “Auto Set”.
Open the main menu and tap “Auto” to open the auto range menu for the corresponding settings. When the
oscilloscope auto range function is turned on, the oscilloscope will automatically set various parameters,
including: vertical scale, horizontal time base, trigger level, etc. When the signal is connected, these parameters
will automatically change, and the signal does not need to be operated again after the change. The oscilloscope
will automatically recognize and make the appropriate changes.
⚫ Auto range: Turn the auto range function on or off
⚫ Vertical scale: Turn on the vertical scale automatic adjustment function;
⚫ Horizontal time base: Turn on the horizontal time base automatic adjustment function;
⚫ Trigger level: Turns on the auto-adjust trigger level function.
Figure 2-10 Open Auto Range
Auto Range is usually more useful than Auto Set under the following situations:
1) It can analyze signals subject to dynamic changes.
Chapter 2. Quick Start Guide of Oscilloscope
17
2) It can quickly view several continuous signals without adjusting the oscilloscope. This function is very
useful if you need to use two probes at the same time, or if you can only use the probe with one hand
because the other hand is full.
3) Control the automatic adjustment setting of the oscilloscope.
2.11 Load Factory Settings
Open the main menu, tap “User Settings” to enter the user setting page. Tap “Factory Settings” and the dialog
box for loading factory settings will pop-up. Press “OK” and load the factory settings. The dialog box for loading
factory settings is shown in Figure 2-11.
Figure 2-11 Load Factory Settings
2.12 Use Auto-calibration
Open the main menu, tap “User Settings” to enter the user setting page. Tap “Auto Calibration” to enter the auto-
calibration mode. When the auto-calibration function is active, the upper left corner of the screen displays
“Calibrating” in red, and after calibrating is finished, the word in red disappears. When the temperature changes
largely, the auto-calibration function can make the oscilloscope maintain the highest accuracy of measurement.
⚫ Auto-calibration should be done without probe.
⚫ Auto-calibration process takes about two minutes.
⚫ If the temperature changes above 10℃, we recommended users perform the auto-calibration.
2.13 Passive Probe Compensation
Before connecting to any channels, users should make a probe compensation to ensure the probe match the input
channel. The probe without compensation will lead to larger measurement errors or mistakes. Probe
compensation can optimize the signal path and make measurement more accurate. If the temperature changes 10℃
or above, this program must run to ensure the measurement accuracy.
Probe compensation may be conducted in the following steps:
1) First, connect the oscilloscope probe to CH1. If a hook head is used, make sure that it is in good
connection with the probe.
2) Connect the probe to the calibration output signal terminal and connect the probe ground to the ground
terminal. As shown in Figure 2-12.
18
Figure 2-12 Probe Connection
3) Open the channel (if the channel is closed).
4) Adjust the oscilloscope channel attenuation coefficient to match the probe attenuation ratio.
5) Tap button or manually adjust the waveform vertical sensitivity and horizontal time base.
Observe the shape of the waveform, see Figure 2-13.
Figure 2-13 Probe Compensation
If the waveform on the screen is shown as “under-compensation” or “over-compensation”, please adjust the
trimmer capacitor until the waveform shown on the screen as “correct-compensation”. The probe adjustment is
shown in Figure 2-14.
Chapter 2. Quick Start Guide of Oscilloscope
19
Figure 2-14 Probe Adjustment
The safety ring on the probe provides a safe operating range. Fingers should not exceed the safety ring when
using the probe, so as to avoid electric shock.
6) Connect the probe to all other oscilloscope channels (Ch2 of a 2-channel oscilloscope, or Ch 2, 3 and 4 of a
4-channel oscilloscope).
7) Repeat this step for each channel.
Warning
⚫ Ensure the wire insulation is in good condition to avoid probe electric shock while measuring high
voltage.
⚫ Keep your fingers behind the probe safety ring to prevent electric shock.
⚫ When the probe is connected a voltage source, do not touch metal parts of the probe-head to prevent
electric shock.
⚫ Before any measurement, please correctly connect the probe ground end.

Waveform Horizontally” and “3.2 Adjust the Horizontal Time Base (time/div)”.
3.4 Roll, XY
In the main menu, tap the soft key , then select the desired time base mode. The time base mode is divided
into YT, ROLL, and XY.
Figure 3-5 Display Mode
YT——Normal View Mode of Oscilloscope
In YT mode, the relative relationship between vertical voltage and horizontal time is displayed. Y axis represents
the voltage, X axis represents the time, and the waveform is displayed after triggering (waveform displayed from
left to right).
Note: When the time base is large (such as 200ms and above), sometimes the waveform will not be
displayed for a long time; this is because in YT mode, the waveform must be triggered before display. It is
closely related to the time base and can be roughly calculated as: the number of divisions on the left side
of the trigger position * time base level position; if you want to reduce the waiting time, move the trigger
position to the left.
The case that trigger position is moved out of the waveform screen is not considered here.
ROLL—— ROLL Mode
In ROLL mode, the waveform rolls from right to left to refresh the display (see Figure 3-6 ROLL Mode). The
horizontal time base adjustment range of the ROLL mode in the running state is 200ms/div~1ks/div.
In ROLL mode, trigger related information is invalid, including trigger position, trigger level, trigger voltage, etc.
24
Figure 3-6 ROLL Mode
In ROLL mode, press to stop waveform display; press again to clear waveform display and
restart acquisition; press to execute single sequence, it will stop automatically after completing a full
screen acquisition.
ROLL mode is generally used to observe waveforms with frequencies below 5 Hz.
ROLL mode is defaulted as open. When the time base is greater than 100ms, it automatically enters the ROLL
mode. If the signal to be triggered under a large time base needs to be viewed, turn off the ROLL mode.
Roll mode on and off: In the main menu, tap the soft key . In the “General” option, you can turn the roll
mode on and off (refer to Figure 3-7). When the roll mode is on and the time base is within 200ms~1ks, the
oscilloscope automatically enters the roll mode.

XY——XY Mode
The vertical amount of CH1 is displayed on the horizontal axis in XY mode, and the vertical amount of CH2 is
displayed on the vertical axis (see Figure 3-8 XY Mode).
You can use XY mode to compare the frequency and phase relationship of two signals.
XY mode can be used for sensors to display stress-displacement, flow-pressure, voltage-frequency or voltage-
current, for example: plotting a diode curve.
You can also use the cursor to measure the waveform in XY mode.
Figure 3-8 XY Mode
XY Mode Example
This exercise shows the usual practice of XY display mode by measuring the phase difference between two
signals of the same frequency using the Lissajous method.
1) Connect sine wave signals to CH1 and connect sine wave signals of the same frequency and different phases
to CH2.
2) Press “Auto” set button, tap “Display” in the main menu, then select “XY” in “Time Base”.
3) Drag signals so that they are centered on the display screen. Adjust the vertical sensitivity of CH1 and CH2,
and extend signals for viewing.
The phase difference (θ) can be calculated using the following formula (assuming that the amplitudes of the
two channels are the same):
26
Figure 3-9 XY Time Base Mode Signal, Center on the Display Screen
4) Tap the “Cursor” button to open the horizontal cursor.
5) Set the cursor y2 at the top of the signal and the cursor y1 at the bottom of the signal. Record the Δy value
in the upper right corner of the screen.
6) Move y1 and y2 cursors to the intersection point of the signal and the y-axis. Record the Δy value again.
Figure 3-10 Phase Difference Measurement and Using the Cursor
7) The following formula is used to calculate the phase difference.
For example, if the first Δy value is 9.97V, the second Δy value is 5.72V:
Error! Reference source was not found. ; phase difference error! Reference source was not found.
3.5 Zoom Mode
Zoom is a horizontally expanded version of the normal display. Open the zoom function, the display is divided
into two parts (see Figure 4-11 Zoom Interface). The upper part of the display screen shows the normal display
window view and the lower part shows the zoomed display window.
Chapter 3 Horizontal System

Figure 3-11 Zoom Interface
Zoom window view is the enlarged portion of the normal display window. You can use “Zoom” to view a portion
of the normal window that is horizontally expanded to learn more about signal analysis.
Zoom on/off:
1) Open the pull-up menu and tap button to turn the zoom function on/off.
2) Put three fingers on the touch screen at the same time, slide down to open zoom mode; slide up to turn off
zoom mode. Figure 3-12 shows the operation:
28
Figure 3-12 Open Zoom Function by Three Fingers Sliding Down
Zoom window is framed in a box on the normal window, and the other portion is covered by gray shade not
displayed in the zoom window. This box shows the normal scan portion that was zoomed in the lower bottom.
Tap the time base button to adjust the time base of the zoom window. The size of the box in the normal window
changes according to the time base of the zoom window.
Drag the waveform of the zoom window horizontally to adjust the waveform position. The box in the main
window moves oppositely against the waveform; or directly drag the box in the normal window to quickly locate
the waveform to be viewed.
Note:
1) The minimum time base is displayed in the normal window when the waveform in the screen is exactly
within the memory depth. If the current time base is smaller than the minimum time base in the
normal window at the current memory depth, when the zoom window is opened, the time base in the
normal window is automatically set to the minimum time base in the normal window at the current
memory depth.
2) The cursor, math waveform, and reference waveform are not displayed in the normal window, but
can be displayed in the Zoom window.
3) If Roll mode is stopped, Zoom mode can be turned on, and tap “Run/Stop” to automatically turn off
Zoom mode.
4) When high refresh is turned on and stopped, it is forbidden to enter zoom mode.

The ground level of each displayed analog channel signal is indicated by the channel indicator icon on the
far left of the display screen.
30
4.1 Open/Close Waveform (Channel, Math, Reference Waveforms)
The channel icons , , , , on the right side of the oscilloscope
waveform display area (tap to switch to math channel and reference channel) correspond to the six
channels of CH1, CH2, CH3, CH4, math function and reference channel. Click these six soft keys can cyclically
realize the functions: open the channel, open the channel menu, and close the channel.
Current channel: The oscilloscope can display multiple waveforms at the same time, but only one waveform is
preferentially displayed on the uppermost layer, and the channel that is preferentially displayed on the uppermost
layer is called the current channel. The channel indicator for the current channel is solid, and the channel indicator
for the non-current channel is hollow, as shown in Figure 4-2.
Figure 4-2 Current Channel and Non-Current Channel
The display content of the oscilloscope channel display interface includes the sampling mode, vertical scale,
vertical scale sensitivity button, probe ratio, bandwidth limitation, etc. of the channel, as shown in Figure 4-3.
Figure 4-3 Channel Display Interface
When CH1 is on, but the state is not the current channel, tap CH1 waveform or vertical sensitivity or channel
indicator or vertical sensitivity button or current channel selection button to set CH1 as the current
channel, as shown in Figure 4-4.

b. the current channel menu can be moved anywhere on the screen;
c. only the open channel is displayed in the channel switching menu;
d. when the math or reference waveform is opened, the current channel switching menu is automatically
opened.
32
4.2 Adjust Vertical Sensitivity
Tap the vertical sensitivity or buttons on the right side of the channel icon to adjust the vertical display
of the waveform corresponding to the channel, so that the waveform is displayed on the screen at an appropriate
size.
The vertical sensitivity scale (V/div) after each adjustment is displayed on the channel icon. For example,
means that the current vertical sensitivity of CH1 is 1.0V/div.
The vertical sensitivity coefficient adjusts the vertical sensitivity of the analog channel in steps of 1-2-5 (the
probe attenuation coefficient is 1X), and the vertical sensitivity range of 1:1 probe is 1mV/div-10V/div
(optionally minimum at 500uV/div).
4.3 Adjust Vertical Position
The method of adjusting vertical position is as follows:
1) Coarse adjustment: In the waveform display area, hold the waveform and put one finger to slide up and
down for changing the vertical position of the waveform.
2) Fine adjustment: After the waveform moves vertically, click the fine adjustment button in the lower left
corner of the screen to fine adjust the vertical position of the waveform for the current channel.
3) After moving the channel up and down, tap , select the channel to be adjusted in the "vertical gear"
item, and the grounding level of the channel can be moved to the center in the vertical direction of the screen.

4.4 Open Channel Menu
Tap the channel icon (channel is open) to open the channel menu.
The channel menu is shown in Figure 4-7. Channel waveform inversion, channel bandwidth limit, probe type,
probe attenuation factor, channel coupling mode, and sampling mode can be set in the vertical menu.
Figure 4-7 Channel Switching Icon and Menu
4.4.1 Set Channel Coupling
Tap the icon under “Coupling Mode” and select “DC”, “AC” and “GND” channel coupling modes in the pop-up
box.
DC: DC coupling. Both the DC component and the AC component of the measured signal can pass, and can be
used to view waveforms as low as 0 Hz without large DC offset.
AC: AC coupling. Measured DC signal is blocked, and only the AC component can be allowed to pass, and used
to view waveforms with large DC offsets.
GND: Internal input ground, disconnecting from external input.
The oscilloscope is connected to the square wave signal with a frequency of 1KHz, an amplitude of 2V and an
offset of 1V. The waveforms of the channel couplings of DC, AC, and GND are shown in Figures 4-8, 4-9, and
4-10.

Note: This setting is only valid for the current channel. To switch from the current channel, just tap the channel icon, channel
indicator icon or horizontal position pointed by the channel indicator icon for direct switching. You do not need to exit the
menu.
4.4.2 Set Bandwidth Limit
Open the channel menu, find the “Bandwidth” selection box in the channel menu, set bandwidth limit, high-pass
filtering and low-pass filtering as needed.
Full Bandwidth: Allows signals of all frequencies to pass.
20M Bandwidth: Only signals with frequencies below 20MHz are allowed to pass, and signals above 20MHz
are effectively attenuated.
High Pass: Only signals above the lower limit of the currently set frequency are allowed to pass.
Select high pass, tap the frequency box , open the frequency setting interface, tap “MHz” and
“KHz” to select the frequency scale, drag or tap the slide bar for coarse adjustment of the maximum frequency
allowed to pass, tap “+”, “-” buttons to precisely adjust the frequency.
Low pass: Only signals below the currently set frequency upper limit are allowed to pass. (with the settings same
as High Pass)
High-pass filtering and low-pass filtering can be set within the frequency range of 30kHz-100MHz.
The difference in bandwidth limitation can be visualized by the waveform. The full bandwidth is shown in Figure
4-11, the 20M bandwidth is shown in Figure 4-12, the high pass is shown in Figure 4-13, and the low pass is
shown in Figure 4-14.

4.4.5 Set Probe Attenuation Coefficient
When measuring with a probe, the correct measurement result can only be obtained by setting the correct probe
attenuation ratio. In order to match the actual probe attenuation ratio, it is necessary to adjust the channel
attenuation factor correspondingly under the channel menu. When probe attenuation ratio is changed, the
corresponding attenuation ratio must be set on the channel menu to ensure the correctness of the waveform
amplitude and measurement result displayed by the oscilloscope.
Probe attenuation ratio and menu attenuation ratio are shown in the table below:

5.1 Trigger and Trigger Adjustment
What is Trigger?
The oscilloscope can capture a waveform only when it meets a preset condition first. This action of capturing the
waveform according to the condition is Trigger. The so-called capture waveform is that the oscilloscope grabs a
signal and displays it. If it is not triggered, there is no waveform display.
What can Trigger be used for?
(1) The oscilloscope can stably display a periodic signal.
Figure 5-1 Stably Displayed Periodic Signal
Figure 5-2 Non-Stably Displayed Periodic Signal
Chapter 5 Trigger System
41
(2) Grab the segment you want to observe from a fast and complex signal
Figure 5-3 Abnormal Signal in Periodic Signals
Figure 5-4 Abnormal Signal Captured by Setting Trigger Level
What is Forced Trigger?
When the oscilloscope does not meet the trigger condition, the artificial or automatic oscilloscope trigger is the
forced trigger. It means that the oscilloscope only grabs a signal segment for display regardless of whether the
condition is met or not.
Automatic forced trigger is set in the menu. In the trigger settings, there is usually a trigger mode option, which
can be set as “Normal” or “Auto”. Normal trigger means trigger after meeting the set condition. Automatic trigger
is a kind of forced trigger. The oscilloscope will be force triggered if it does not trigger for a certain period of
time.
42
Figure 5-5 Oscilloscope Trigger Mode Setting
If a signal feature is not understood, the oscilloscope should be set as “Auto” mode, which can ensure that the
oscilloscope can also display the waveform when other trigger settings are not correct. Although the waveform
is not necessarily stable, it can provide the intuitive judgment for our further adjustment of the oscilloscope. The
signal in Figure 5-5 is the result of forced trigger in “Auto” mode.
When we set a specific trigger condition for a specific signal, especially when the time interval for satisfying the
trigger condition is long, we need to set the trigger mode to “Normal” so as to prevent the oscilloscope from
automatic forced trigger.
Figure 5-6 shows a conceptual demonstration of the acquisition memory. In order to understand the trigger event,
the acquisition memory can be divided into pre-trigger and post-trigger buffers. The position of the trigger event
in the acquisition memory is defined by the time reference point and trigger position (horizontal delay) settings.
Figure 5-6 Conceptual Demonstration of Acquisition Memory
All events displayed to the left of the trigger point occur before trigger. These events are called pre-trigger
messages that show events before the trigger point. All events to the right of the trigger point is called post-trigger
messages. The number of delay ranges available (pre-trigger and post-trigger messages) depends on the selected
time base and memory depth.

Adjust trigger position (horizontal delay)
Fingers swipe left and right in the waveform display area, the trigger point will move horizontally, the
horizontal delay time changes, and the delay time is displayed at the top center of the screen, that is, the distance
between the trigger point and the center line of the waveform display area is displayed.
Figure 5-7 Horizontal Delay
When the trigger point is located on the left side to the center line of the waveform display area, the
delay time is displayed as a positive value; When the trigger point is located on the right side to the time
reference point , and the delay time is displayed as a negative value; the trigger point overlaps with the
center line of the waveform display area, and the delay time is zero.
Trigger level
Trigger level is the signal voltage corresponding to the set trigger point. When the trigger level is changed, a
horizontal line will appear temporarily on the screen to tell you the level position (the specific value of the trigger
level is displayed in the upper right corner of the screen), then the horizontal line disappears, the trigger level is
indicated by a small arrow and the indication icon can be dragged to adjust the trigger level value. The
trigger level is shown in Figure 5-8 (the arrow indicates the trigger level line).
Horizontal Delay

Figure 5-8 Trigger Level
Adjust trigger level
The trigger level can be coarsely adjusted and finely adjusted.
Coarse adjustment: Slide up and down in the trigger level adjustment area.
Fine adjustment: After moving the trigger level, tap the fine adjustment button in the lower left corner of the
screen for fine adjustment of the trigger level.
Note: Fine adjustment requires activation of the trigger level control function.
In addition, if the final operation of the oscilloscope is to adjust the trigger level, tap and select the
"level" item to adjust the trigger level to 50% of the waveform amplitude of the trigger source channel.
Set trigger hold-off time
The trigger rejection time can set up the waiting time of the oscilloscope after the trigger and before the trigger
circuit is reconnected. During rejection, the oscilloscope does not re-trigger until the end of the rejection time,
and the rejection time can be used to stably trigger complex waveforms. The trigger rejection time ranges from
200ns~10s.
The rejection may be used to trigger on repetitive waveforms with multiple edges (or other events) between
waveform repetitions. If the shortest time between triggers is known, the rejection may also be used to trigger on
the first edge.
For example, to obtain stable trigger on the repetitive pulse trigger shown below, set the rejection time to a
value >200ns but <600ns.
Chapter 5 Trigger System
45
Figure 5-9 Trigger Rejection Time
Set trigger hold-off time:
1) Tap “Trigger” on the main menu to open the trigger menu. Under “Common”, tap the box after “Rejection
Time” to open the rejection time adjustment interface. The trigger time is displayed on the upper left, the
fine adjustment time scale is displayed on the upper right, and the coarse time scale is displayed below, as
shown in Figure 5-10.
Figure 5-10 Trigger Hold-off Time Set Interface
2) When adjusting the time, drag or tap the coarse adjustment scale for coarse adjustment, and then drag the
fine adjustment scale for fine adjustment of the rejection time.
Trigger rejection operation prompt
It is typically used for complex waveforms. The correct rejection setting is usually slightly smaller than one
repetition of the waveform. Setting the rejection time to this time can become the only trigger point for the
repetitive waveform.
Changing the time base setting will not affect the trigger rejection time.
Using Zoom function, you can tap “Run/Stop” to stop, then horizontally move and zoom the data to find the
position where the waveform is repeated. Use the cursor to measure this time and then set the rejection time.
⚫ Use “SingleSEQ” button for single acquisition
Usually when performing a single acquisition, you must initiate some operations on the measured equipment,
and the oscilloscope is not desired to trigger automatically before these operations. The trigger condition indicator
is displayed in the upper left corner of the screen before starting operations in the circuit (this means the
pre-trigger buffer is filled).
5.2 Edge Trigger
When the edge of trigger signal reaches a certain trigger level, the set signal is triggered and generated. Trigger
occurs on either edge of the rising edge (indicating icon at the top of the screen), falling edge ( ) or dual
edge ( ), and the trigger level can be set to change the vertical position of the trigger point on the trigger edge,

namely the intersection point of the trigger level line and the signal edge. The stable waveform can be obtained
by correctly setting the edge trigger coupling mode. Edge trigger menu is shown in the table below:

edge trigger as follows, as shown in Figure 5-11:
⚫ Trigger source: CH1;
⚫ Trigger coupling mode: DC;
⚫ Trigger edge: rising.

2) Adjust the trigger level to ensure that the waveform can be triggered stably, for example, the trigger level
is set to 1V.
Chapter 5 Trigger System
47
Trigger coupling description
When the edge trigger setup menu is opened, the trigger coupling option is displayed below the menu. Trigger
coupling includes DC, AC, HFRei., LFRej., NoiseRej, see Figure 5-12:
Figure 5-12 Trigger Coupling Menu
1) DC coupling - allows DC and AC signals to enter the trigger path.
2) AC coupling - removes any DC offset voltage from the trigger waveform.
When the waveform has a large DC offset, stable edge triggering can be achieved using AC coupling.
3) HFRej. (High Frequency Rejection Coupling) - removes high frequency components from the trigger
waveform, using high frequency rejection to remove high frequency noises or noises from fast system clocks,
from trigger paths such as AM or FM radio stations.
4) LFRej. (Low Frequency Rejection Coupling) - removes any unnecessary low frequency components from
the trigger waveform, for example, power line frequencies that can interfere with correct trigger.
When there is low frequency noise in the waveform, stable edge triggering can be obtained using LF
rejection coupling.
5) NoiseRej. (Noise Rejection Coupling) - Noise rejection can add extra hysteresis to the trigger circuit. By
increasing the trigger hysteresis band, the possibility of noise triggering can be reduced. But it also reduces
the trigger sensitivity, so triggering the oscilloscope requires a slightly larger signal.
Note: Trigger coupling is independent of channel coupling.
5.3 Pulse Width Trigger
The trigger happens when the trigger signal pulse width (8ns~10s, the trigger type indication icon at the top of
the screen is ) reaches the set condition and the signal voltage reaches the set trigger level. Pulse width

The selected pulse polarity icon is displayed in the upper right corner of the display screen. The positive
pulse is higher than current trigger level (CH1 positive pulse indication icon ), and the
negative pulse is lower than current trigger level (CH1 negative pulse indication icon ).
When triggered on positive polarity pulse, if the restrictions are true, the trigger will happen on the high-to-
low transition of the pulse; when triggered on negative polarity pulse, if the restrictions are true, the trigger
will happen on the low-to-high transition. (Figure 5-14 Negative Pulse Level Flip)

Figure 5-16 Trigger Time T>80ns
⚫ Equal to the time value (=)
For example, for positive pulse, if it is set as T=80ns, the trigger will happen stably only when the pulse
width is equal to 80ns (Figure 5-17 Trigger Time T=80ns).
Figure 5-17 Trigger Time T=80ns
⚫ Not equal to the time value (≠)
For example, for positive pulse, if it is set as T≠80ns, the trigger will happen stably only when the pulse
width is not equal to 80ns (Figure 5-18 Trigger Time T≠80ns).
Figure 5-18 Trigger Time T≠80ns
The trigger pulse width time can be set as 8ns~10s.
Tap the pulse width time setting box to pop up the time adjustment interface (as shown in

CSV files
CSV file structure
CSV format contains the basic information of the saved data: save time, file name, data length, sampling interval,
trigger time, source, vertical scale, vertical offset, vertical accuracy, horizontal time base, horizontal accuracy,
probe multiples.
The data and length of CSV files can be saved up to 70K/35K depending on the single/dual channel while being
saved. If the oscilloscope record length or the displayed data length is less than 70K/35K, the data length of CSV
files changes either. For example, when the record length is set to 14/7/3.5K, there will be 7000 sample points in
the dual channel CSV file.
Max and Min in CSV files
If running Min or Max measurements, Min and Max values displayed on the measurement results screen may
not appear in CSV files.
Explanation: If the oscilloscope sampling rate is 1GSa/s, sampling will be once every 1ns. If the horizontal scaling
is set to 10us/div, the data of 140us will be displayed (because there are 14 divisions on screen). To find the total
number of samples, the oscilloscope will perform: 140us×1GSa/s=140K sampling, which require the oscilloscope
to display 140K times of sampling using 600-pixel columns. The oscilloscope extracts 140K samples into 600-
pixel columns, and this extraction will track Min and Max values of all points represented by any given column.
These Min and Max values will be displayed in this screen column.
The similar process is applied to reduce sampled data and produce records that can be used to perform various
analyses, such as measurements and CSV data. This analysis record (or measurement record) is much larger than
78
600 and may actually contain up to 60,000 points. However, once the number of points sampled exceeds 60,000,
some extraction method is required. The extraction factor used to generate the CSV record is configured to
provide the best estimate of all samples represented by each point in the record. Therefore, Min and Max values
do not appear in CSV files.

Multiplication is useful when viewing the power relationship, if one of the channels is proportional to the current.
8.2 FFT Measurement
FFT is used to calculate the Fast Fourier Transform using the analog input channel. FFT record specifies the
digitization time of the source and converts it to the frequency domain. After selecting the FFT function, FFT
spectrum is plotted as amplitude in V-Hz or dB-Hz on the oscilloscope display screen. The reading of the
horizontal axis changes from time to frequency (Hz), while the unit of the vertical axis changes from volt to V or
dB.

2) Tap spectrum type “Line/Decibel” to open the FFT window (see Figure 8-3 FFT Window).
3) Tap the Operation Source box to select the channel for which FFT transform is required.
4) Tap the window box to select the window function applied to the FFT input signal.
Selection of window function
In the FFT transform, four different FFT windows can be selected.
Chapter 8 MATH and Reference
83
Each window is alternatively used between frequency resolution and amplitude accuracy, and the appropriate
window may be selected according to the characteristics of the following windows.
⚫ Rectangular window
This is the best window type for resolution frequencies that are very close to the same value, but this
type is the least effective at accurately measuring the amplitude of these frequencies. It is the best type
of measuring the spectrum of non-repetitive signals and measuring the frequency component close to
DC.
Use the “Rectangular” window to measure transients or bursts of signal levels before or after almost
the same event. Moreover, this window can be used to measure equal-amplitude sine waves with very
close frequencies and wideband random noises with relatively slow spectral variations.
⚫ Hamming window
This is the best window type for resolution frequencies that are very close to the same value, and the
amplitude accuracy is slightly better than the “Rectangular” window. The Hamming type has a slightly
higher frequency resolution than the Hanning type.
Use Hamming to measure sinusoidal, periodic, and narrowband random noises. This window is used
for measuring transients or bursts of signal levels before or after events with significant differences.
⚫ Hanning window
This is the best window type for measuring amplitude accuracy but less effective for resolving
frequencies.
Use Hanning to measure sinusoidal, periodic, and narrowband random noises. This window is used for
measuring transients or bursts of signal levels before or after events with significant differences.
⚫ Blackman-Harris window
This is the best window type for measuring frequency amplitude, but worst for measuring the resolution
frequency.
Use the Blackman-Harris measurement to find the main single-signal frequency waveform for higher
harmonics.
Since the oscilloscope performs FFT transform on the finite-length time record, the FFT algorithm
assumes that YT waveform is continuously repeated. Thus, when the period is integral, the amplitudes
of YT waveform at the beginning and at the end are the same, and waveform will not interrupt. However,
if the period of YT waveform is not integral, the waveform amplitudes at the beginning and at the end
are different, resulting in high-frequency transient interruption at the junction. In the frequency domain,
this effect is called leakage. Therefore, to avoid leakage, the original waveform is multiplied by a
window function, forcing the values at the beginning and at the end to be zero.
84
Note: Signals with DC components or deviations can cause errors or deviations in the FFT waveform components. AC
coupling can be selected to reduce DC components.

Adjust FFT waveforms
Waveform position
⚫ Select math channel as the current channel. After touching math waveform on the screen with one
finger, adjust the waveform display position by dragging upward and downward, leftward and
rightward, or tap the fine adjustment button in the lower left corner of the screen for fine adjustment
⚫ Move the channel horizontally, tap , tap the "time base" item, and move the leftmost (0Hz)
of the waveform to the horizontal center of the screen.
Horizontal time base scale
Select math channel as the current channel, tap the time base adjustment button, and adjust the horizontal time
base scale. The horizontal time base is stepped in 1-2-5, and the waveform changes either.
For FFT measurement, the reading of the horizontal axis changes from time to frequency (Hz), and it no longer
shares the same time base with other analog channels. Therefore, before adjusting the horizontal frequency scale,
the math channel must be set as the current channel.

Tap in the bottom right corner of the screen to enter the second channel selection area. Tap
button to open the reference menu, see Figure 8-5.
Figure 8-5 Reference Channel Menu
When there are already waveforms loaded into the reference channel, click “Open/Close” button to open or close
the reference channel; the reference waveform is displayed in blue-violet, and the four stored waveforms can be
displayed simultaneously, wherein the current reference waveform is brighter than non-current reference
waveforms.
When there are no waveforms loaded into the reference channel, turn on the “Call” switch to call waveforms.
Take R1 as an example, with operation steps as follows:
1) Tap to open the reference menu.
2) Tap the “Call” file box under R1 to open the reference file column.
3) Click the name of the reference waveform file to be called. The file is loaded into R1 channel. Then, R1
86
channel is turned on as the current channel waveform, and the reference waveform channel icon is
highlighted. The displayed state changes from “Close” to “Open”. As in Figure 8-6, the brighter reference
waveform is shown as the current reference channel.
If there are already files loaded into the reference channel, tap to open the reference channel of all
loaded reference files; tap to close all currently opened reference waveforms. A single reference channel
may also be opened with the Open/Close button.
Figure 8-6 Restore Reference Waveform
Close the reference waveform:
1) In the reference menu, tap “Open/Close” button in R1 to close the reference waveform.
2) Repeat step 1 to close other reference channels. When all reference waveform channels are closed, the
reference waveform channel icon becomes gray.
3) Tap to turn off all reference waveforms.
Reference waveform movement and time base adjustment
The horizontal or vertical movement and zoom of reference waveforms are independent of analog channels, and
the adjustments among different reference waveform channels are also independent of each other.
To adjust the reference waveform of a channel, first set the channel as the current channel, and then adjust the
reference waveform by move or zoom (in accordance with the analog channel method).
The scale and time base of the current channel reference waveform are displayed on the reference button. After
Chapter 8 MATH and Reference
87
switching the current reference channel, the scale and time base on the reference button change with the change
of current reference channel.

series oscilloscope.

10.1 Sampling Overview
To understand the sampling and sampling modes of the oscilloscope, you need to understand the sampling
principle, aliasing, oscilloscope bandwidth and sampling rate, oscilloscope rise time, required oscilloscope
bandwidth, and the influence of memory depth on the sampling rate.
Sampling principle
According to the Nyquist sampling principle, for a bandwidth-limited signal with the maximum frequency f
MAX
,
the equidistant sampling frequency f
S
must be twice as large as the maximum frequency f
MAX
, so that a unique
signal can be reconstructed without aliasing.
Aliasing
Aliasing occurs when the signal is under sampled (f
S
<2f
MAX
). Aliasing is signal distortion caused by incorrectly
reconstructing low frequencies from a small number of sampling points.
Figure 10-1 Aliasing
Oscilloscope bandwidth and sampling rate
The oscilloscope bandwidth usually refers to the lowest frequency at which the input signal sine wave is
attenuated by 3dB (-30% amplitude error).
For oscilloscope bandwidth, according to the sampling principle, the required sampling rate is f
S
=2f
BW
. However,
this principle assumes that there is no frequency component exceeding f
MAX
(f
BW
in this case) and requires a
system with ideal brick-wall frequency response.
Chapter 10 Sampling System
95
Figure 10-2 Theoretical Brick-Wall Frequency Response
However, digital signals have frequency components that exceed the fundamental frequency (the square wave
consists of sine waves at fundamental frequency and an infinite number of odd harmonics), and for bandwidths
of 500MHz and below, the oscilloscope typically has Gaussian frequency response.
Figure 10-3 Sampling Rate and Oscilloscope Bandwidth
The oscilloscope bandwidth is limited to 1/4 sampling frequency and reduces the frequency response above the
Nyquist frequency.
Therefore, in fact, the oscilloscope sampling rate should be 4 times or more of its bandwidth: f
S
≥4f
BW
. This can
reduce aliasing and cause greater attenuation in the aliased frequency components.
Oscilloscope rise time
The oscilloscope rise time is closely related to its bandwidth. The rise time of an oscilloscope with Gaussian type
frequency response is approximately 0.35/f
BW
(based on the standard from 10% to 90%).
The oscilloscope rise time is not the fastest edge speed that an oscilloscope can accurately measure. It is the
fastest edge speed that the oscilloscope can produce.
Desired oscilloscope bandwidth
The oscilloscope bandwidth required to accurately measure signal is primarily determined by the rise time of the
Frequency
Attenuation
Frequency
Attenuation
Aliasing
96
signal rather than the frequency of the signal.
The following steps can be used to calculate the required oscilloscope bandwidth:
1) Determine the fastest edge speed.
Rise time information is typically obtained from the published device specifications used in the design.
2) Calculate the maximum “actual” frequency component.
According to Dr. Howard W. Johnson’s book “High-Speed Digital Design–A Handbook of Black Magic”,
all fast edges have wirelessly continuous frequency components. However, there is a turning point (or
“inflection point”) in the fast edge spectrum at which frequency components above f
knee
are negligible in
determining the signal shape.
f
knee
=0.5/signal rise time (based on 10% - 90% threshold)
f
knee
=0.4/signal rise time (based on 20% - 80% threshold)
3) The multiplication factor for the desired accuracy is used to determine the required oscilloscope bandwidth.

Use softkeys in the button area to start and stop the oscilloscope acquisition system: Run/Stop button
and Single Sequence Acquisition button.
⚫ When the Run/Stop button is displayed in green, it indicates that the oscilloscope is running,
that is, it meets the trigger condition and data acquisition is being performed. The green “ ” or “ ”
is displayed in the upper left corner of the screen.
To stop data collection, tap the Run/Stop button. After stopping, the screen displays the last acquired
waveform.
⚫ When the Run/Stop button is displayed in red, it indicates that data acquisition has stopped.
The red “ ” is displayed in the upper left corner of the screen.
To resume data acquisition, press the Run/Stop button again.
Chapter 10 Sampling System
97
⚫ To capture and display single acquisition (whether the oscilloscope is running or stopped), tap the
single sequence key for a single acquisition.
10.3 Select Sampling Mode
Open the channel menu, tap the sampling mode option under “Sample”, and choose among the four sampling
modes: normal, average, peak and envelope in the pop-up box.
The sampling modes of all channels are same. That is, if the sampling mode of any channel is changed, the
sampling mode of all channels is changed at the same time.
Normal sampling mode
Oscilloscope samples signal through equivalent time intervals to build waveform. When the time base of 20 ns
or faster is chosen, the oscilloscope automatically performs an interpolation algorithm that inserts difference point
between sampling points.
This mode produces the best display effects for most waveforms.
Peak sampling mode
In peak sampling mode, when the horizontal time base setting is low, the minimum and maximum sample values
are retained to capture rare events and narrow events (with any noise expanded). This mode will display all pulses
that are at least as wide as the sampling period.
When the time base is set to 200ms and above, the oscilloscope will automatically exit the peak sampling mode
and switch to the normal sampling mode.
Burr or narrow pulse capture
Burr is the rapid change in waveform that is usually narrower than waveform. Peak sampling mode can be used
to view burr or narrow pulses more easily. In the peak sampling mode, narrow burr and transition edges are
brighter than in those in the “normal” sampling mode, making them easier to see.
Applying the peak sampling mode can avoid signal aliasing but show more real noises.
98
Figure 10-4 Sine Wave with Burr, Normal Sampling Mode
Figure 10-5 Sine Wave with Burr, Peak Sampling Mode
Use peak detection mode to find burrs
1) Connect signal to the oscilloscope to be stably displayed.
2) To find burr, select the peak sampling mode in Sampling Mode option in the Channel menu.
3) In the menu, tap “Display” → “Persistence”, then tap “∞” (infinite persistence). The oscilloscope will restart
sampling data and display them on the screen.
Chapter 10 Sampling System
99
4) Use the zoom mode to represent the characteristics of burr:
a. Tap the “Zoom” button in the main menu to open the zoom window.
b. To get a better resolution of burr, expand the time base to set the expanded portion of the normal
window view around burr.
Average sampling mode
The average sampling mode averages multiple acquisition results to reduce random or unrelated noises in the
displayed signal. The average of multiple sampling results requires stable trigger.
The average number can be set in the selection box after the average sampling mode, and can be set to eight order
of magnitudes: 2, 4, 8, 16, 32, 64, 128 and 256.
The higher the average number is, the slower the response of the displayed waveform-to-waveform changes. A
compromise must be made between the response speed of waveform versus the changes and the degree of noise
reduction shown on the signal.
Use average sampling mode
1) Open the channel menu and select the average sampling mode in the sampling mode option.
2) Press the number box on the right of the average sampling mode box to pop up the average number and then
tap it to set the average number that can best eliminate displayed waveform noises.
Figure 10-6 Waveform after choosing the average sampling mode, with average number 128
Envelope sampling mode
In the envelope sampling mode, the superposition effect of several sampled waveforms can be observed. The
maximum and minimum values of one signal can be captured in the specified N sample data, and the number of
100
waveform superpositions can be set to 2, 4 , 8, 16, 32, 64, 128, 256 or ∞.
Figure 10-7 AM Signal in Envelope Sampling Mode (64)
10.4 Record Length and Sampling Rate
The record length is the data volume for each captured waveform. For example, if the record length is 700K, it
means that 700K sample points are captured by one trigger.
In the main menu, tap to enter the record length setting menu, which can be set by tapping the
corresponding record length.
Figure 10-8 Record Length
In normal refresh mode, if it is a single channel, the record length can be set to 14k, 140k, 1.4M, 14M, 28M,
Auto; if it is dual channel, the record length can be set to 7k, 70k, 0.7M, 7M, 14M, Auto; if it is three or four
channels, the record length can be set to 3.5k, 35k, 0.35M, 3.5M, 7M, Auto.
Record length and sampling rate
The record length is data volume collected per waveform capture. For example, if the record length is 0.7M, it
means that 700K sample points are captured by one trigger.
The oscilloscope record length and sampling rate have the following relationship:
Chapter 10 Sampling System
101
Sampling rate = record length/acquisition time
Generally, the oscilloscope acquisition time is exactly the display time on the current entire screen (current
horizontal time base×14).
For example, if the oscilloscope has the memory depth of 700K, the sampling rate of 1GSa/s, and the horizontal
time base of 50us/div, the acquisition time is 700us, which is 50us/div×14div.
However, when the fast time base (below 20 ns) or the record length is set to a fixed value, the oscilloscope
acquisition time does not necessarily represent the display time on the current entire screen.
For example, if the oscilloscope has the memory depth of 700K, the sampling rate of 1GSa/s, and the horizontal
time base of 20ns, the acquisition time is 700ns, which is 2.5 times of the current display time on the entire screen.
Or, if the memory depth is 140K (fixed value), the sampling rate is 1GSa/s, and the horizontal time base is 1us,
the acquisition time is 140us, which is 10 times of the current display time on the entire screen.
For a single channel in a channel pair, the maximum sampling rate of the tBook mini series oscilloscope is 1GSa/s.
If any two channels are opened, the sampling rate of the two channels will halved. For example, when CH1 and
CH3 are opened, the sampling rates of CH1 and CH3 are both 500 MSa/s.
If any three channels or all four channels are opened, the sampling rate per channel will become 1/4 of the
maximum sampling rate. For example, when CH1, CH2 and CH3 are opened, the sampling rates of CH1, CH2
and CH3 are 250 MSa/s for each of them.

12.1 UART (RS232/RS422/RS485) Bus Trigger and Decode
For correctly decoding UART(RS232/RS422/RS485) bus data and making trigger stable, the bus configuration,
trigger mode setting and trigger level need to be adjusted.
⚫ Bus configuration
Tap or to open the bus configuration menu, as shown in Figure 12-4. The RX channel must
be chosen and the following parameters must be set according to measured signals:
Idle-level — Choose Idle Low or Idle High to match the idle state of measured equipment. For RS232, Idle
Low may be chosen.
Note: RS232 industry standard uses “negative logic”, namely high level is logic “0” and low level is
logic “1”.
Check — Choose odd, even or none depending on measured equipment.
#Bits — Set the number of bits in UART word to match measured equipment (5-9 bits available).
BaudRate — Choose the baud rate that matches signal in measured equipment.
The baud rate can be set within the range from 1.2Kb/S to 8.000Mb/S.
118
Display — Choose hexadecimal, binary or ASCII code display.
Figure 12-4 UART Bus Configuration Menu
When word is displayed in ASCII, 7-bit ASCII format is used. Valid ASCII characters are between 0x00 and
0x7F. To display in ASCII, at least 7 bits in the “#Bits” must be chosen. If ASCII is chosen and the data
exceeds 0x7F, the data will be displayed in hexadecimal.
Click the baud rate setting box to open the baud rate selection column. If Custom is chosen, click to pop up
the virtual soft keyboard, select the bit to be modified, enter value, and click “Enter” on the virtual soft
keyboard to complete setting. The baud rate can be set from 1.2Kb/S to 8.000Mb/S. The virtual soft keyboard
is shown in Figure 12-5:

Chapter 12 Serial Bus Trigger and Decode (Optional)
119
Note: When there is parity bit, the data word length indicates the total length of data bit plus parity
bit. When there is no parity bit, the data word length is considered to be the length of data bit. For
example, if the data word length is 8bit, when there is no parity bit, it means that the total length of
data bits is 8bit; when there is parity bit, it means that the total length of data bits is 7bit, and there is
parity bit of 1 bit.

Chapter 14 Reference
This chapter contains the measurement category suitable for the oscilloscope and the environmental level of
pollution degree supported. You are recommended to read this chapter carefully to understand the conditions of
use of the tBook mini series oscilloscope.
⚫ Measurement Category
⚫ Pollution Degree
Chapter 14 Reference
153
14.1 Measurement Category
Oscilloscope measurement category
tBook minim series oscilloscopes are primarily used for measurements in Measurement Category I.
Measurement category definitions
Measurement category I is for measurements performed on circuits not directly connected to MAINS. Examples
are measurements on circuits not derived from MAINS, and specially protected (internal) MAINS derived circuits.
In the latter case, transient stresses are variable; for that reason, the transient withstand capability of the equipment
is made known to the user.
Measurement category II is for measurements performed on circuits directly connected to the low voltage
installation. Examples are measurements on household appliances, portable tools and similar equipment.
Measurement category III is for measurements performed in the building installation. Examples are
measurements on distribution boards, circuit-breakers, wiring (including cables, bus-bars, junction boxes,
switches, socket-outlets) in the fixed installation, and equipment for industrial use and some other equipment, for
example, stationary motors with permanent connection to the fixed installation.
Measurement category IV is for measurements performed at the power source of the low-voltage installation.
Examples are electricity meters and measurements on primary overcurrent protection devices and ripple control
units.
Transient withstand capability
Maximum input voltage of the analog input
Category I 300Vrms, 400Vpk.
14.2 Pollution Degree
Pollution Degree
tBook mini series oscilloscopes can operate in environments with
pollution degree 2 (or pollution degree 1).
Pollution Degree
Categories
Pollution degree 1: No pollution or only dry, non-conductive pollution
occurs. The pollution has no influence. For example: a clean room or air-
conditioned office environment.
Pollution degree 2: Normally only dry, non-conductive pollution occurs.
Occasionally temporary conductivity caused by condensation may occur.
For example: general indoor environment.
Pollution degree 3: Conductive pollution, or dry, non-conductive pollution
occurs which becomes conductive due to condensation. For example:
154
sheltered outdoor environment.
Pollution degree 4: Pollution that generates persistent conductivity
through conductive dust, rain, or snow. For example: outdoor locations.
14.3 Software and Firmware Updates
Micsig often releases software and firmware updates for its products. To search for the firmware update for your
oscilloscope, please download it from the website (download address of the latest upgrade package:
http://www.micsig.com/html/list_60.html)
To view the currently installed software and firmware, click "setting" in "homepage" to display the software and
firmware information of oscilloscope in the system.

Chapter 15 Troubleshooting
155
Chapter 15 Troubleshooting
1. If the oscilloscope does not start up at power on, please follow steps below:
⚫ Check the power cord to verify whether it has been connected properly and whether the power supply
is normal;
⚫ Check the power on/off buttons to ensure it has been pushed, and if you are using battery, check whether
the battery is in good condition;
⚫ Restart the oscilloscope after the checks above;
⚫ Contact Micsig if the problem persists, and we will provide service to you.
2. If acquired waveforms do not display on the screen when the signal source is connected, please follow
the steps below:
⚫ Check whether the probe is connected correctly in the BNC socket;
⚫ Check whether the probe is connected correctly in the signal source;
⚫ Check whether the trigger type is correctly selected;
⚫ Check whether trigger conditions are set correctly
⚫ Check whether signal source is working properly;
⚫ Check whether the channel is turned on;
⚫ Check whether the vertical scale factor is set correctly;
⚫ Check whether the instrument is in single-sequence waiting state for trigger
⚫ Tap to resample signal.
3. If the measured voltage amplitude is 10 times greater or smaller than the actual value:
⚫ Check whether the set attenuation factor of the channel is consistent with the attenuation factor of the
actually used probe.
4. There is a waveform display, but cannot be stable:
⚫ Check the trigger source on the trigger type menu to ensure that it is consistent with the actually used
signal channel;
⚫ Check the trigger type: edge trigger is adopted for general signal, and video trigger mode for video
signal. Only the correct trigger mode is used, the waveform can be displayed stably;
⚫ Check signal source noise. Set the trigger coupling mode to be high-frequency rejection or low-
frequency rejection to filter out high frequency or low frequency noise interference
5. A waveform is displayed but inconsistent with the input waveform:
156
⚫ Check whether the coupling mode setting in the channel menu is correct.
6. If there is no display after pressing button:
⚫ Check whether the trigger mode is “Normal”, and whether the trigger level is beyond the scope of the
waveform. Center the trigger level and set the trigger mode as “Auto”.
⚫ Check whether the picture is displayed in full screen, and if so, exit the display.
7. If the display becomes slower after setting average times of sampling:
⚫ If the average times are above 32, it is normal for the general speed to become slow.
⚫ You can reduce the average times.
8. Staircase waveform is displayed:
⚫ This phenomenon is normal because the horizontal time base is too low, and the horizontal time base
may be increased to raise the horizontal resolution, and then improve the display;
⚫ The display type may be “line”. The connection between sampling points may lead to the display of
staircase waveform. This problem can be solved by setting the display type as “point” display mode.
9. There is persistence of vision in waveform display:
⚫ This phenomenon is normal because the persistence time may be set too long, and the waveform
persistence shows persistence of vision;
⚫ The reason may be that sampling mode is set to envelope of sampling, and the sampling mode can be
modified to normal waveform for normal display
10. During measurement, the measured value is displayed as -----:
⚫ This phenomenon is normal. When the channel waveform displays beyond the waveform display area,
the measured value is displayed as -----. If the channel vertical sensitivity or vertical position is adjusted,
the measured value can be displayed correctly;
⚫ This phenomenon is normal. When there is no full-cycle waveform in the waveform display area, the
measured value may be displayed as -----. If the time base is adjusted, the measured value will be
displayed correctly.
⚫ This phenomenon is normal, and the measured value of the FFT waveform is displayed as -----.
11. When viewing pictures, no pictures are displayed:
⚫ Check whether the USB option in the settings is set as the USB storage device. If it is the USB storage
device, please change to other options.
12. The oscilloscope will be black if there is no operation for a period of time:
⚫ Check whether the standby time setting in the setting is disabled; if it is not disabled, it will
Chapter 15 Troubleshooting
157
automatically standby at the set time.
13. Oscilloscope will automatically shut down after no operation for a period of time:
⚫ Check whether the shutdown time setting is Disabled; if it is not Disabled, it will automatically shut
down when the set time is reached.
14. CSV files cannot be selected when loading reference:
⚫ CSV files are not the supported format that can be loaded into reference channels.
15. Tap the button during the use of oscilloscope, there is no beep sound:
⚫ Check whether the sound volume setting is correct.
16. Oscilloscope backlight has low brightness:
⚫ Check whether the backlight settings are correct.
17. A waveform being moved changes abruptly:
⚫ Check whether the picture is displayed in full screen.
18. Turn off the channel at Auto state:
⚫ This phenomenon is normal. At Auto state, the channel with an amplitude less than 10mV will be turned
off.
19. Function buttons are pressed without response:
⚫ Check whether the picture is displayed in full screen.
