Trigger Setting
The trigger determines when the oscilloscope starts to acquire data and display a waveform. When a trigger is set up
properly, it can convert unstable displays or blank screens into meaningful waveforms.
If the oscilloscope wants to acquire a waveform, it collects enough data so that it can draw the waveform to the left of
the trigger point. The oscilloscope continues to acquire data while waiting for the trigger condition to occur. The
oscilloscope continues to acquire enough data so that it can draw the waveform to the right of the trigger point after it
detects a trigger.
The Edge trigger determines whether the scope finds the trigger point on the rising or the falling edge of the signal.
Select Edge trigger mode to trigger on Rising edge or Falling edge.
Trigger Mode: Edge.
Trigger Sweep: Set the sweep mode to Auto, Normal or Single.
Auto: Performs the acquisition freely in absence of valid trigger. It allows the generation of untriggered
waveforms.
Normal: 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.
Single: Acquire waveform when trigger occurred, then stop to acquire.
Trigger Source: You can use the trigger source options to select the signal that the oscilloscope uses as a trigger.
Select the trigger source signal (CH1, CH2 or EXT).
Trigger Slope: Set the slope to Rising (+) or Falling (-).
Rising: Trigger on rising edge
Falling: Trigger on falling edge
Also user can also set trigger parameters in the bottom right sidebar.
