Trigger Commands

Trigger control commands

The trigger determines when the oscilloscope starts to acquire data and display a

waveform. When a trigger is set up properly, it converts unstable displays into

meaningful waveforms.

When the oscilloscope starts to acquire a waveform, it collects enough data so that

it can display the waveform to the left of the trigger point. The oscilloscope

continues to acquire data while waiting for the trigger condition to occur. After it

detects a trigger, the oscilloscope continues to acquire enough data so that it can

display the waveform to the right of the trigger point.

Trigger control commands include:

 :TRIGger:MODE

 :TRIGger<mode>:SOURce

 :TRIGger<mode>:LEVel

 :TRIGger<mode>:SWEep

 :TRIGger<mode>:COUPling

 :TRIGger:HOLDoff

 :TRIGger:STATus?

We will give specific explanations for each command in the following part.
