Selecting Burst Mode
When burst mode is selected, any modulation or
sweep modes will be automatically disabled. If no
settings have been configured, the default settings
for output amplitude, offset and frequency are
used.
Burst Modes
Burst mode can be configured using Triggered (N Cycle mode) or
Gated mode. Using N Cycle/Triggered 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. Triggered mode
can use internal or external triggers.
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.
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.
