4-7-2. 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, Gated 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.

Note
In gate mode, burst count, burst cycle, trigger source will
be ignored, Also trigger source will be only in the external
trigger signal.
4-7-3. Burst Frequency
In the N Cycle and Gated modes, the waveform frequency sets the repetition rate
of the burst waveforms. In N-Cycle mode, the burst is output at the waveform
frequency for the number of cycles set. In Gated mode the waveform frequency is
output while the trigger is high. Burst mode supports sine, square or ramp
waveforms.
