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.
