8-15. Burst Mode Commands
8-15-1. Burst Mode Overview
Burst mode can be configured to use an internal trigger (N Cycle mode) or an
external trigger (Gate mode) using the Trigger INPUT terminal on the rear panel.
Using N Cycle mode, each time the function generator receives a trigger, the
function generator will output a specified number of waveform cycles (burst). After
the burst, the function generator will wait for the next trigger before outputting
another burst. N Cycle is the default Burst mode.
The alternative to using a specified number of cycles, Gate mode uses the
external trigger to turn on or off the output. When the Trigger INPUT signal is
high*, waveforms are continuously output (creating a burst). When the Trigger
INPUT signal goes low*, the waveforms will stop being output after the last
waveform completes its period. The voltage level of the output will remain equal to
the starting phase of the burst waveforms, ready for the signal to go high* again.
*assuming the Trigger polarity is not inverted.
Only one burst mode can be used at any one time. The burst mode depends on
the source of the trigger (internal, external, manual) and the source of the burst.
