Burst (DDS Only)

After a Force Trigger command is received, the frequency (or phase)
defined in the Modulation Editor buffer is generated until another
Force Trigger is received.

At the next Force Trigger, the period of the waveform is completed
with the previous frequency (or phase) entry before the second
stage frequency (or phase) is generated.

Once the last frequency (or phase) is exhausted, the waveform's
frequency (or phase) resumes using the first value entry in the
Modulation Editor list.

The generation can be interrupted at any time by a Force Stop
command.

The Duration Time associated to any frequency (or phase) is ignored
when using Burst/DDS mode.
