Features and Function
HDG2000 Series Arbitrary Waveform Generator 37
Modulating Waveform Shape
The instrument accepts an internal, external or external trig modulation source.
The modulating waveform shape (internal source) may be:
Sine wave
Square with 50% duty cycle
UpRamp with 100% symmetry
Triangle with 50% symmetry
DnRamp with 0% symmetry
Noise - white gaussian noise
Arb - Arbitrary waveform
SCPI:
SOURce<n>:MOD:PM:INTernal:FUNCtion SINusoid|SQUare|RAMP
Modulating Waveform Frequency
The instrument accepts an internal, external or external trig modulation source.
Modulating frequency (internal source): from 2 MHz to 500 kHz, default 100 Hz.

Phase Deviation
The phase deviation setting represents the peak variation in phase of the modulated waveform
from the carrier waveform. The phase deviation can be set from 0 to 360 degrees (default 180).
