Triggering on Noisy Waveforms

To reduce jitter on the screen when triggering on noisy waveforms, you can use a noise rejection filter. Continue from step 3 of the previous example as follows:

4	Select On Trigger, jump to Noise
	reject Filter.
5	Set Noise reject Filter to On.

Observe that the trigger gap has increased. This is indicated by a taller trigger icon .

Making a Single Acquisition

To catch single events, you can perform a single shot acquisition (one-time screen update). To set up the test tool for a single shot of the input A waveform, continue from step 3 again:

4 Select Single Shot.

5 Accept the settings.

The word WAITING appears at the top of the screen indicating that the test tool is waiting for a trigger. As soon as the test tool receives a trigger, the waveform is displayed and the instrument is set to hold. This is indicated by the word HOLD at top of the screen.
