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.
The test tool will now have a screen like Figure 29.
6
Arm the test tool for a new single
shot.
Tip
The test tool stores all single shots in the replay
memory. Use the Replay function to look at all
the stored single shots.
