Features and Function
HDG2000 Series Arbitrary Waveform Generator 41
SCPI:
SOURce<n>:MOD:PWM:INTernal:FUNCtion SINusoid|SQUare|RAMP
Modulating Waveform Frequency
The instrument accepts an internal, external or external trig modulation source.
Modulating frequency (internal source): 2MHz to 500KHz. The default is 100 Hz.

PWM Deviation
The PWM deviation setting is the peak variation in width of the modulated pulse waveform.

Modulating Source
The instrument accepts an internal, external or external trig modulation source.
Modulating source: Internal (default), external or external trig. The External modulation source
may be up to 100 kHz.
If you select the External modulating source, the deviation is controlled by the ±5 V signal level
on the front-panel MOD connector. For example, if you have set the deviation to 10%, then a +5
V signal corresponds to a 10% change in width. Lower signal levels produce less deviation.
If you select the External Trig modulating source, the deviation is controlled by the +5 V signal
level on the front-panel TRIG connector.
