Burst Mode Commands
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.
