Click “Setup-> Trigger”
The following figure shows the trigger system control.
The trigger determines when the oscilloscope begins to acquire data and display a waveform.
Once a trigger is properly set up, the oscilloscope can convert unstable displays or blank screens
to meaningful waveforms. Here introduce some basic concepts about trigger.
Operation Basics
USER’S MANUAL 26
Trigger Source: The trigger can be generated with multiple sources. The most common one is the
input channel. Whether the input signal is displayed or not, it can trigger normal operations. Also
the trigger source can be any signal connected to an external trigger channel or the AC power line
(only for Edge triggers). The source with the AC power line shows the frequency relationship
between the signal and the AC commercial power.
Trigger Mode: The oscilloscope has five types of triggers: Edge, Pulse Width, Slope, Video and
Timeout.
Edge Trigger uses the analog or digital test circuits for triggering. It happens when the
input trigger source crosses a specified level in a specified direction.
Pulse Width Trigger can trigger normal or abnormal pulses that meet trigger conditions.
Slope Trigger uses the rise and fall times on the edge of signal for triggering.
Video Trigger performs a field or line trigger through standard video signals.
Timeout Trigger happens after the edge of signal reaches the set time.
Trigger Sweep: You can select the Auto or Normal mode to define how the oscilloscope acquires
data when it does not detect a trigger condition. Auto Mode performs the acquisition freely in
absence of valid trigger. Normal Mode updates the displayed waveforms only when the
oscilloscope detects a valid trigger condition. Before this update, the oscilloscope still displays the
old waveforms. This mode shall be used when you want to only view the effectively triggered
waveforms. In this mode, the oscilloscope displays waveforms only after the first trigger. To
perform a single sequence acquisition, push the SINGLE SEQ button.
Trigger Position: The horizontal position control establishes the time between the trigger position
and the screen center.
Slope and Level: The Slope and Level controls help to define the trigger. The Slope option
determines whether the trigger point is on the rising or falling edge of a signal. To perform the
trigger slope control, press the TRIG MENU button, select an Edge trigger, and use the Slope
button to select rising or falling. The TRIGGER LEVEL knob controls the trigger point is on which
position of the edge.
Trigger slope can be rising or falling
Rising Edge
Falling Edge
Trigger level can be
adjusted vertically

4.2 Capturing a Single-Shot Signal
To capture a single event, it needs to gather some pre-test knowledge of the signal in order to set
up the trigger level and slope correctly. For example, if the event is derived from 3.3V COMS logic,
a trigger level of 1.2 or higher Volts should work on a rising edge. Do these steps as follows:
1. Set the probe and the channel attenuations to X 10.
2. Set up the trigger in the Trigger Menu, or in the Trigger Setting window.
1) Adjust the Trigger Mode to Edge.
2) Set the Trigger Sweep to Single.
3) Set the Trigger Source to CH1.
4) Set the Trigger Slope to “+” which means you select the rising edge.
5) Adjust the Volts/Div and the time base in a proper range for the signal.
6) Drag the trigger level sign on the waveform display screen to proper position. It ally higher a
little above the normal level.
7) Click button to start capturing. When the trigger conditions are met, data appears on the
display representing the data points that the oscilloscope obtained with one acquisition.
This function helps to capture the signal occurrence easily, such as the noise with large
amplitude; set the trigger level higher a little above the normal level and press and wait. When
noise occurs, the instrument will record the waveform before and after the trigger.
4.3 The Application of the X-Y Operation
X-Y Plot acts to analyze correlation of data of two channels. Lissajous diagram is displayed in the
screen when you use X-Y Plot, which enables to compare frequencies, amplitudes and phases of
counterpart waveform against the reference waveform. This makes it possible to compare and
analyze frequency, amplitude and phase between input and output.
Do these steps as follows:
1. Set the probe attenuation to “x10”. Set the switch to “x10” on the probes.
2. Connect the CH1 probe to the input of the circuit, and connect the CH2 probe to the output of
the circuit.
3. Click button.
4. Adjust the vertical scale and offset to display approximately the same amplitude signals on
each channel.
5. Select X-Y format at Horizontal window. The oscilloscope will displays a Lissajous pattern
representing the input and the output characteristics of the circuit.
6. Adjust the scale and offset of the horizontal and vertical to a desirable waveform display.
Application Example
USER’S MANUAL 55
7. Apply the Ellipse Method to observe the phase difference between the two channels.
Signal in X-Y Format:
Instruction of the Ellipse Method
Sinθ = A/B or C/D, where θ = phase shift (in degrees) between the two signals.
From the formula above:
θ = _arcsine (A/B) or _arcsine (C/D)
θ must be in the range of (0~π/2) or (3π/2~2π) if the main axis of the ellipse is between I and III
quadrant, . If the main axis is at II and IV quadrant, θ must be in the range of (π/2~π) or (π~3π/2).
