The Modulation Mode menu allows setting the trigger for the modulating
signal. Available options include Single, Continuous, and Burst.
Single
A
RBITRARY

When the Force Trigger command is given, the carrier signal, see
Advanced Waveform Editing (on page 61), is modulated with the
edited, modulating signal samples.

The last sample of the modulating signal is applied to the signal
carrier until a Force Stop command is applied.
DDS

When a Force Trigger command is applied, the frequencies (or
phases) inserted in the Modulation Editor are generated one after
the other for a time interval specified on the Durations field.

The last frequency (or phase) is repeated until a Force Stop
command is received.

The sequence can be interrupted at any time by a Force Stop
command.
Continuous
A
RBITRARY

When the Force Trigger command is given, the carrier signal, see
Advanced Waveform Editing (on page 61), is modulated with the
edited modulating signal samples.

Once the last sample of the modulating signal is reached, ArbStudio
returns to the first modulating signal sample until a Stop command
is applied.
DDS

When a Force Trigger command is applied, the frequencies (or
phases) inserted in the Modulation Editor are generated one after
the other in a continuous mode.

After the generation of the last frequency (or phase), ArbStudio
returns to the first frequency (or phase).

The sequence can be interrupted at any time by a Force Stop
command.
