Edge Trigger
The trigger determines when the oscilloscope starts to acquire data and display a wave- form.
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 oscilloscope finds the trigger point on the rising or the
falling edge of a signal. Select Edge trigger mode to trigger on Rising edge or Falling edge.
Mode: Select the trigger mode.
Sweep:
Set the sweep mode to
Auto, Normal
or
Single
.
Auto: Acquire waveform even no trigger occurred
Normal: Acquire waveform when trigger occurred.
Single: Acquire waveform when trigger occurred then stop
Source: You can use the trigger source options to select the signal that the oscilloscope uses as a
trigger. The source can be any signal connected to a channel BNC.
