Chapter 2 To Set the Vertical System RIGOL
MSO5000-E User Guide 2-3
To Adjust the Vertical Scale
Vertical scale indicates the voltage value per grid in the vertical axis of the screen. I t
is often expressed in V/ div. While you adjust the vertical scale, the display amplitude
of the waveform would enlarge or reduce. The scale information of the channel
status label (e.g. as shown in the following f igure) at the lower section of the screen
would change accordingly.
The adjustable range of the vertical scale is related to the currently set probe ratio
and input impedance. By default, the probe ratio is 1X and the input impedance is 1
MΩ. The adjustable range of the vertical scale is from 500 μV/div t o 1 0 V/ d iv.
When CH1 is turned on, you can adjust the vertical scale with the following three
methods:
Rotate Vertical
SCALE that corresponds to CH1 to adjust the vertical scale
(clockwise to reduce the scale and counterclockwise to increase).
Enable the touch screen function and adjust the vertical scale with the pinch &
stretch gesture on the touch screen. For details, refer to the "Pinch & Stretch"
section.
Enable the touch screen function, and tap the channel status label at the bottom
of the screen. The following window is displayed. Tap the
icon at the
right side of the Scale input f ield to decrease or increase the scale. You can also
tap the Scale input f ield to input a specif ic value with the displayed numeric
keypad.
In the vertical control area (Ver tical) on the front panel, press Vertical
SCALE
to adjust the vertical scale in "Coarse" (by default)
or "Fine" mode. You can also
press 1 More Fine to enable or disable f ine adjustment.
Fine adjustment: Rotate Vertical SCALE to further adjust the vertical scale
within a relatively smaller range to improve vertical resolution. I f the amplitude
of the input waveform is a little bit greater than the full scale under the current
scale and the amplitude would be a little bit lower if the next scale is used, f ine
adjustment can be used to improve the amplitude of waveform display to view
signal details.
Coarse adjustment (take counterclockwise as an example): Rotate Vertical
SCALE to set the vertical scale at 1-2-5 step, i.e. 500 μV/div, 1 mV/div, 2 mV/div,
5 mV/ div, 10 mV/div…10 V/div.

Vertical Expansion
When changing the vertical scale of the analog channel by rotating the Vertical
SCALE
knob, you can select to expand or compress the waveform around the
"Center" or "GND" (Ground). By default, "GND" is selected under Expand.
Press 1 More, then press Expand continuously to select "Center" or "GND".
Center: when the vertical scale is changed, the waveform will be expanded or
compressed around the screen center.
GND: when the vertical scale is changed, the waveform will be expanded or
compressed around the signal ground level position.
To Adjust the Vertical Offset
Vertical offset indicates the offset of the signal ground level position of the waveform
from the screen center in the vertical direction. I ts unit is consistent with the
currently selected amplitude unit (refer to "Amplitude Unit"). When adjusting the
vertical offset, the waveforms of the corresponding channel moves up and down.
The vertical offset information (as shown in the following f igure) in the channel
status label at the bottom of the screen will change accordingly.
The adjustable range of the vertical offset is related to the current input impedance,
probe ratio, and vertical scale.
When CH1 is turned on, you can adjust the vertical offset with the following four
methods:
Rotate Vertical
OFFSET that corresponds to CH1 to adjust the vertical
offset within the adjustable range. Rotate this knob clockwise to increase the
vertical offset, and rotate it counterclockwise to reduce the vertical offset.
Pressing down the knob can quickly reset the vertical offset (set the vertical
offset to 0).
Menu setting: Press 1 More Offset, and then the numeric keypad is
displayed. I nput the offset value with the numeric keypad.
Enable the touch screen, and then adjust the vertical offset with the drag
gesture. For details, refer to the "Drag" section.
Enable the touch screen function, and tap the channel status label at the bottom
of the screen. The following window is displayed. Tap the
icon at the
right side of the Offset input f ield to decrease or increase the offset. You can
also tap the Offset input f ield to input a specif ic value with the displayed
numeric keypad.

Channel Coupling
The undesired signals can be f iltered out by setting the coupling mode. For example,
the signal under test is a square waveform with DC offset.
When the coupling mode is "DC": the DC and AC components of the signal under
test can both pass the channel.
When the coupling mode is "AC": the DC components of the signal under test
are blocked.
When the coupling mode is "GND", the DC and AC components of the signal
under test are both blocked.
Press 1 to open the setting menu of CH1. Then, press Coupling continuously or
rotate the multifunction knob to select the desired coupling mode (by default, it
is DC). The current coupling mode is displayed in the channel status label at the

screen, and then touch the CH1 setting menu to select the desired coupling mode.
DC AC GND
Bandwidth Limit
MSO5000-E series supports the bandwidth limit function. Setting the bandwidth limit
can reduce the noises in the displayed waveforms. For example, the signal under test
is a pulse with high frequency oscillation.
When the bandwidth limit is disabled, the high frequency components of the
signal under test can pass the channel.
When you enable the bandwidth limit and limit it to 20 MHz, the high frequency
components found in the signal under test that are greater than 20 MHz are
attenuated.
Press 1 to open the setting menu of CH1.Then, press BW Limit continuously or
rotate the multifunction knob to select the desired bandwidth limit. Press down
the knob to select it. By default, it is OFF. When the bandwidth limit is enabled, the

To Adjust the Horizontal Timebase
Horizontal timebase, also called the horizontal scale, refers to the time of each grid in
the horizontal direction of the screen. I t is usually expressed in s/div. The adjustable
range of the horizontal timebase is related to the model type.
While you change the horizontal timebase, the displayed waveforms of all channels
are expanded or compressed horizontally relative to the current selected horizontal
reference baseline (refer to "Horizontal Expansion"). The horizontal timebase at
the upper-left corner of the screen will be changed accordingly, as shown in the
f igure below.
You can adjust the horizontal timebase with the following three methods:
Rotate Horizontal
SCALE to adjust the horizontal timebase within the
available range (clockwise to reduce the horizontal timebase and
counterclockwise to increase).
Enable the touch screen function and adjust the horizontal timebase with the
pinch & stretch gesture on the touch screen. For details, refer to the "Pinch &
Stretch" section.
Enable the touch screen function, and tap the horizontal timebase label
at the top of the screen. The following window is displayed. Tap the
icon at the right side of the Scale input f ield to decrease or increase the
horizontal scale. You can also tap the Scale input f ield to input a specif ic value

Note: When the delayed sweep is enabled, rotate the Horizontal
SCALE knob
to adjust the timebase for the delayed sweep. The delayed sweep timebase
displayed in the center of the screen will be changed accordingly, as shown in
the following f igure.
To Adjust the Horizontal Position
Horizontal position, also called trigger position, refers to the trigger point position of
the waveforms of all channels in the horizontal direction relative to the screen center.
When the waveform trigger point is at the left (right) side of the screen center, the
horizontal position is a positive (negative) value.
While you change the horizontal position, the waveform trigger points and the
displayed waveforms of all channels are moved left and right. The horizontal position
at the right-upper corner of the screen changes accordingly, as shown in the figure
below.
You can adjust the horizontal position with the following three methods:
Rotate Horizontal
POSI TI ON to adjust the horizontal position of the
waveforms of all channels. When you rotate it clockwise, the waveform trigger
point moves right on the screen; when you rotate it counterclockwise, the
waveform trigger point moves left on the screen. Pressing down the knob can
quickly reset the horizontal position (reset to 0).
Enable the touch screen function and adjust the horizontal position with the
drag gesture on the touch screen. For details, refer to the "Drag" section.
Enable the touch screen function, and tap the horizontal position label
at the top of the screen. The following window is displayed. Tap the

Timebase Mode
MSO5000-E series supports three available timebase modes: YT mode, XY mode,
and ROLL mode. By default, the timebase m o d e i s YT.
Press Acquire Timebase Mode on the front panel, and then rotate the
multifunction knob to select the desired timebase mode. Then, press down the
knob to select the mode. You can also press Timebase Mode continuously to select
the mode or enable the touch screen to tap the desired mode and select it.
YT Mode
I n this mode, the Y axis represents voltage, and the X axis represents time.
Note: Only when this mode is enabled, can delayed sweep be turned on. I n this
mode, when the horizontal timebase is equal to or greater than 200 ms/div,
the instrument enters slow sweep mode. For details, refer to descriptions in
"ROLL Mode".
XY Mode
I n this mode, both the X axis and the Y axis represent the voltage. The mode
changes the display from voltage-time display mode to voltage-voltage display. You
can use the Lissajous method to measure the phase deviation of the two input
signals whose frequencies are the same. The following f igure shows the
measurement schematic diagram of phase deviation.

According to sinθ= A/ B or C/ D, θ is the phase deviation angle between the two
channels. The def initions of A, B, C, and D are shown in the above f igure. The phase
deviation angle is obtained, that is:
θ= ±arcsin( A/ B) or ±arcsin( C/ D)
I f the principal axis of the ellipse is within Quadrant I and I I I , the phase deviation
angle obtained should be within Quadrant I and I V, namely within (0 to π/ 2) or (3π/ 2
to 2π). If the principal axis of the ellipse is within Quadrant II and I V, the phase
deviation angle obtained should be within Quadrant I I and I I I, namely within (π/ 2 to
π) or (π to 3π/ 2).
The XY function can be used to measure the phase deviation occurred when the
signal under test passes through a circuit network. Connect the oscilloscope to the
circuit to monitor the input and output signals of the circuit.
Application example: measures the phase deviation between the input signals of
two channels.
Use Lissajous method
1. Connect one sine signal to CH1, and then connect another sine signal (with the
same frequency and amplitude as the previous one but a 90° phase deviation
from the previous one) to CH2.
2. Press AUTO, after you select "XY" mode, rotate the Horizontal
SCALE to
adjust the sample rate properly to obtain a better view of Lissajous graph for
observation and measurement.
3. Rotate the Vertical
SCALE knob that corresponds to CH1 and CH2
respectively to make the signals easy to observe. Then, a circle, as shown in the
figure below, should be displayed.
4. Observe the measurement result shown in the f igure above. According to the
measurement schematic diagram of the phase deviation (as shown in Figure
4-1
), A/ B(C/ D) = 1. Thus, the phase deviation angle of the two channel input
signals is
θ= ±arcsin1= 90° .
RIGOL Chapter 4 To Set the Sample System
4-4 MSO5000-E User Guide
Note:
I n XY mode, CH1 and CH2 are forced to be enabled. The maximum sample rate
in XY mode is 2 GSa/ s. Generally, a longer sample waveform can ensure better
display effect of Lissajous f igure. But due to the limitation of the memory depth,
you have to reduce the waveform sample rate to acquire a longer waveform
(refer to the introduction in "Memory Depth"). Therefore, during the
measurement, reducing the sample rate properly can achieve better display
effect of Lissajous f igure.
The following functions are disabled in XY mode:
"Delayed Sweep", "To Select the Display Type", "Scale", "Protocol
Decoding", "Pass/ Fail Test", "Waveform Recording & Playing", and
"Digital Channel".
ROLL Mode
I n this mode, the waveform scrolls from right to left to update the display. The
available range of the horizontal scale is from 200 ms to 1 ks. Press More Auto
ROLL to select "ON". The system automatically enters the ROLL mode, and there is
no slow sweep.
Note:
I f the current delayed sweep is enabled, then when you enable the ROLL mode,
the delayed sweep is disabled automatically. When you re-enable the "YT" mode,
the delayed sweep will be re-enabled.
The following functions cannot be set in ROLL mode:
"To Adjust the Horizontal Position" (available when the oscilloscope is in
"Stop" operating status), "Delayed Sw eep", "To Trigger the Oscilloscope",
"Protocol Decoding", "Pass/ Fail Test ", "Waveform Recording &
Playing", and "To Set the Persistence Time".
Slow Sweep
I t is similar to the ROLL mode. I n YT mode, when the horizontal timebase is set to
200 ms/ div or smaller, the instrument enters the "slow sweep" mode in which the
instrument f irst acquires the data at the left of the trigger point and then waits for
a trigger event. After the trigger occurs, the instrument continues to f inish the
waveform at the right of the trigger point. When observing the low-frequency
signal in the slow sweep mode, it is recommended that you set "
Channel
Coupling" to "DC".
Chapter 4 To Set the Sample System RIGOL
MSO5000-E User Guide 4-5
Acquisition Mode
The acquisition mode is used to control how to generate waveform points from the
sample points.
MSO5000-E supports the following four acquisition modes: Normal, Average, Peak,
and High Resolution. By default, the acquisition mode is Normal.
Press Acquire Acquisition on the front panel, and then rotate the multifunction
knob to select the desired acquisition mode. Then, press down the knob to
select the mode. You can also press Acquisition continuously to select the mode or
enable the touch screen to tap the desired mode and select it.
Normal
I n this mode, the oscilloscope samples the signal at a specif ied f ixed time interval to
rebuild the waveform. For most of the waveforms, using this mode can produce the
optimal display effects.
Average
I n this mode, the oscilloscope averages the waveforms from multiple samples to
reduce the random noise of the input signal and improve the vertical resolution.
Greater number of averages can lower the noise and increase the vertical resolution;
while at the same time, it will slow the response of the displayed waveform to the
waveform changes.
When you select "Average" mode, press Averages and rotate the multifunction
knob
or use the numeric keypad to set the desired number of averages. You can
also use the pop-up numeric keypad to input the average count. When the average
count value is in power-of-2 increments, a prompt message "Trim average count" is
displayed. At this time, a value that is smaller than the one you input and the closest
to power-of-2 increments will be input automatically. For example, if you input 9 with
the numeric keypad, the average count will be input 8 automatically.
The number of averages can be set to 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048,
4096, 8192, 16384, 32768, or 65536. By default, it is 2.

Peak
I n this mode, the oscilloscope acquires the maximum and minimum values of the
signal within the sample interval to get the envelope of the signal or the narrow pulse
that might be lost. I n this mode, signal aliasing can be prevented, but the noise
displayed would be larger.
I n this mode, the oscilloscope can display all the pulses whose pulse widths are at
least the same as the sample period.
High Resolution
This mode uses an over-sample technique to average the neighboring points of the
sample waveform. This reduces the random noise on the input signal, generates a
much smoother waveform on the screen and improves the vertical resolution. This is
generally used when the sample rate of the digital converter is greater than the

storage rate of the acquisition memory.
Note:
The "Average" and "High Res" modes use different averaging methods. The
former uses "Multi-sample Average" and the latter uses "Single-sample
Average".
I n "High Res" mode, the signal bandwidth does not exceed 1/ 32 of the sampling
rate.
I n "High Res" mode, the highest waveform refresh rate mode is not supported.
Sampling Mode
This oscilloscope only supports the real-time sampling mode. I n this mode, the
oscilloscope produce the waveform display from samples collected during one trigger
event. The highest real-time sample rate on the analog channel of MSO5000-E series
is 4 GSa/ s. The current sample rate is displayed under CH SampleRate, and you
can press More CH SampleRate to view it.
Sample Rate
Sampling is the process of converting the analog signal into the digital signal at a
specif ied time interval and then restoring them in sequence. The sample rate is the
reciprocal of the time interval.
The sample rate of the analog channel is related to the current channel mode. The
maximum real-time sample rate in the single-channel mode of the oscilloscope is 4
GSa/ s. The maximum real-time sample rate in the all-channel mode is 2 GSa/ s.
Note:
The sample rate is displayed both in the status bar at the upper part of the
screen and in the CH SampleRate menu. To indirectly modify the sample
rate, rotate the Horizontal
SCALE knob to adjust the horizontal
Tip
Press RUN/ STOP on the front panel to stop sampling, and then the oscilloscope
will maintain its last captured graph. You can still expand or zoom the waveforms
by using the horizontal and vertical control knobs.
Tip
Single-channel mode: only one of the channels (CH1 or CH2) is enabled.
All-channel mode: CH1 and CH2 are both enabled.
Note that the currently enabled channel should be used as the trigger source at
this time.

timebase or modify the memory depth.
The impact of low sample rate on the waveform:
1. Waveform Distortion: when the sample rate is too low, some waveform
details are lost, and the sample waveform displayed is rather different from the
actual waveform of the signal.
2. Waveform Aliasing: when the sample rate is twice lower than the actual
signal frequency (Nyquist Frequency), the frequency of the waveform rebuilt from
the sample data is smaller than the actual signal frequency.
3. Waveform Leakage: when the sample rate is too low, the waveform rebuilt
from the sample data does not reflect all the actual signal information.

LA Sample Rate
LA sampling is the process of sampling on the compared digital signals at a certain
time interval. LA sample rate is the reciprocal of the time interval. For example, if the
LA sample rate is 500 MSa/ s, it indicates that the oscilloscope will make data
acquisition on the digital signals at an interval of 2 ns. The maximum LA sample rate
of the oscilloscope is 1 GSa/ s, and its display value is related to the sample rate of the
current analog channel.
Note:
The digital signals here mentioned refers to the signal obtained from the
comparison between the input signal and the user-defined threshold level. The
rule of the comparison is that when the amplitude of the input signal is greater
than the threshold level, it is judged to be the logic high level; when the
amplitude of the input signal is smaller than the threshold level, it is judged to
be the logic low level.
LA sample rate is displayed under the LA SampleRate menu. To indirectly
modify the LA sample rate, rotate the Horizontal
SCALE knob to adjust
the horizontal timebase or modify the memory depth.
Memory Depth
Memory depth refers to the number of points of the oscilloscope that can store in one
trigger acquisition. I t reflects the storage capability of the acquisition storage. This
oscilloscope is equipped with memory depth of up to 100 Mpts (option).

Press Acquire Mem Depth, then rotate the multifunction knob to switch to
the desired memory depth, and then press down the knob to select the option. You
can also press the Mem Depth key continuously or enable the touch screen to
select the memory depth. By default, the memory depth is Auto. The memory depth
of the analog channel is related to the current channel mode.
I n single-channel mode, the memory depths available include Auto, 1 Kpts, 10
Kpts, 100 Kpts, 1 Mpts, 10 Mpts, 25 Mpts, 50 Mpts, and 100 Mpts.
I n all-channel mode, the memory depths available include Auto, 1 Kpts, 10 Kpts,
100 Kpts, 1 Mpts, 10 Mpts, 25 Mpts and 50 Mpts.
Note: I n "Auto" mode, the oscilloscope selects the memory depth automatically
according to the current sample rate.
LA Memory Depth
Press Acquire More to view the memory depth of the current digital channel
under LA Mem Depth. The LA memory depth will change with the memory depth of
the analog channel, and cannot be set separately. The maximum LA memory depth is
25 Mpts.
Anti-Aliasing
At a slower sweep speed, the sample rate is reduced, and a dedicated display
algorithm can be used to minimize the possibility of aliasing.
Press Acquire Anti-aliasing to enable or disable the anti-aliasing function. By
default, anti-aliasing is disabled. I n this case, it is more likely to generate waveform
aliasing.
Note: This function should be enabled when the horizontal timebase has a large
deviation from the period of the signal under test (e.g. when the horizontal
timebase is greater than f ive-fold the period of the signal under test).

Chapter 5 To Trigger the Oscilloscope
As for trigger, you set certain trigger condition according to the requirement and
when a waveform in the waveform stream meets this condition, the oscilloscope
captures this waveform as well as the neighboring part, and displays them on the
screen. For the digital oscilloscope, it samples waveform continuously no matter
whether it is stably triggered, but only stable trigger can be stably displayed. The
trigger module ensures that every timebase sweep or acquisition starts from the
user-def ined trigger condition, namely every sweep is synchronous with the
acquisition and the waveforms acquired is overlapped so as to display the stable
waveforms.
Trigger settings should be based on the features of the input signal. To quickly
capture the desired waveform, you need to understand the signal under test. This
oscilloscope provides abundant trigger types that help you focus on the desired
waveform details.

Analog channel input:
Signals input from analog channels CH1-CH2 can all be used as trigger sources. No
matter whether the channel selected is enabled, the channel can work normally.
Digital channel input:
Signals input from digital channels D0-D15 can all be used as trigger sources. No
matter whether the channel selected is enabled, the channel can work normally.
External trigger input:
The external trigger source can be used to trigger on the third channel while all the
other two channels are acquiring data. The trigger signal (e.g. external clock or
signal of the circuit under test) will be connected to EXT or EXT/ 5 trigger source via
the external trigger input terminal [ EXT] connector. You can set the trigger
conditions within the range of the trigger level (from -1 V to + 1 V for EXT or from -5
V to + 5 V for EXT/ 5).
AC line input:
The trigger signal is obtained from the AC power input of the oscilloscope. AC trigger
is usually used to measure signals relevant to the AC power frequency. For example,
stably triggering the waveform output from the transformer of a transformer
substation. I t is mainly used in related measurements of the power industry.

The following is the schematic diagram of the acquisition memory. To easily
understand the trigger event, we classify the acquisition memory into the pre-trigger
buffer and post-trigger buffer.
Figure 5-1 Schematic Diagram of the Acquisition Memory
After the system runs, the oscilloscope operates by f irst f illing the pre-trigger buffer.
I t starts searching for a trigger after the pre-trigger buffer is f illed. While searching
for the trigger, the data sampled will still be transmitted to the pre-trigger buffer (the
new data will continuously overwrite the previous data). When a trigger is found, the
pre-trigger buffer contains the data acquired just before the trigger. Then, the
oscilloscope will f ill the post-trigger buffer and display the data in the acquisition
memory. I f the acquisition is activated via RUN/ STOP, the oscilloscope will repeat
this process; if the acquisition is activated via SI NGLE, the oscilloscope will stop
after f inishing a single acquisition (you can pan and zoom the currently displayed
waveform).

Single: In this trigger mode, the oscilloscope performs a single trigger and
acquisition when the specified trigger conditions are found, and then stops. This
trigger mode should be used when you need to perform a single acquisition of
the specif ied event and analyze the acquisition result (you can pan and zoom
the currently displayed waveform, and the subsequent waveform data will not
overwrite the current waveform). After a single trigger mode is initiated, the
operating status of the oscilloscope is in "STOP" state.
Note: In "Normal" and "Single" trigger modes, pressing Force can generate a
trigger signal forcibly.
I n addition, you can enable the touch screen to set the trigger mode. Enable the
touch screen and tap the trigger setting label
at the upper-right
corner of the screen. Then the following window is displayed. Tap to select "Auto",
"Normal", or "Single" as the trigger mode.
Trigger Coupling
Trigger coupling decides which kind of components will be transmitted to the trigger
module. Please distinguish it from "Channel Coupling".
Note: Tr i g ger coupling is only valid when the trigger type is Edge and the trigger
source is an analog channel.
RIGOL Chapter 5 To Trigger the Oscilloscope
5-6 MSO5000-E User Guide
Press Menu Coupling in the trigger control area (Trigger) on the front panel.
Then, rotate the multifunction knob to select the desired coupling mode (by
default, it is DC). You can also press Coupling continuously to select it or enable the
touch screen to select the desired coupling mode with touch gestures.
DC: allows DC and AC components to pass the trigger path.
AC: blocks the DC components and attenuates signals.
LFR: blocks the DC components and rejects the low-frequency components.
HFR: rejects the high frequency components.
Trigger Holdoff
Trigger holdoff can be used to stably trigger on complex repetitive waveforms that
have multiple edges (or other events) between waveform repetitions (such as pulse
series). Holdoff time indicates the time that the oscilloscope waits for re-arming the
trigger module after generating a correct trigger. The oscilloscope will not trigger
even if the trigger condition is met during the holdoff time and will only re-arm the
trigger module after the holdoff time expires.
For example, to stably trigger the repetitive pulse series as shown in the f igure below,
the holdoff time should be set to a value that is greater than t1 and smaller than t2.
Figure 5-2 Schematic Diagram of Trigger Holdoff
In the trigger control area (Trigger) on the front panel, press Menu Holdoff ( for
some triggers, Holdoff is a sub menu under More, at this time, press Menu
More Holdoff) and then rotate the multifunction knob at a small step to
modify the holdoff time (the holdoff to this time when the waveforms are stably
triggered; by default, the holdoff time is 16 ns). Also, you can use the numeric
keypad to set the holdoff time. The adjustable range of holdoff time is from 8 ns to
10 s.
Tip
When "AC" or "LFR" is selected under Coupling, no trigger level lines and trigger
icons are displayed. When you adjust the trigger level, you can only see the changes
of the trigger level values at the upper-right corner of the screen.

． Error expressions in decoding
In RS232 decoding, parity error and/ or EOF (end of frame) error may occur.
Parity Error
When a parity error is detected during the decoding, red error report
information will be displayed. For example, when "none" is chosen for the
parity on the transmitter and "odd" is chosen for the parity on the decoder,
the following parity error information
(its display form is related to the
value of the horizontal timebase) occurs. Wherein, the number of 1s in the
8-digit f igure (00000100) is an odd number, and the parity bit should be 0.
However, the parity bit detected on the Tx is 1; thus a parity error occurs.
Chapter 11 Protocol Decoding RIGOL
MSO5000-E User Guide 11-13
EOF Error
This error is generated when the EOF condition is not met. For example, if
the Stop Bit is set to 1.5, but the actual stop bits is less than 1.5 bits, then
the red error report information
(its display form is related to the
value of the horizontal timebase) is displayed in the following f igure.
Parity Error and EOF Error
When both the parity error and the EOF error are detected, the error report
