Fluke 19xC-2x5C

Users Manual

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:

Select On Trigger, jump to Noise

reject Filter.

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:

Select Single Shot.

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.

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.
