Single Event Acquisition; N-Cycle Trigger - Fluke ScopeMeter 190 Series III User Manual

Single Event 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:
1. Use the cursor and E to select Single Shot.
The word MANUAL 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. See

The test tool stores all single shots in the replay memory. Use the Replay function to look
at all the stored single shots. See

N-Cycle Trigger

direction that complies with the selected trigger slope.
To select N-Cycle triggering, continue from step 3 again:
1. Use the cursor and E to select On Trigger or Single Shot, jump to Trigger Filter.
