Hantek HDG2022B User Manual

SCPI Programming Reference
HDG2000 Series Arbitrary Waveform Generator 88
Selects frequency at which output pulse width shifts through its pulse width deviation. The
waveform used as the modulating source will operate at that frequency, within frequency limits of
that waveform.
Parameter
Typical Return
2 mHz to 500 kHz, default 100Hz
+1.000000000000000E+02
Set internal PWM frequency to 100Hz: SOURce1:MOD:PM:INTernal:FREQuency 100
When you select an arbitrary waveform as the modulating source, the frequency changes to the
frequency of the arbitrary waveform, which is based on the sample rate and the number of
points in the arbitrary waveform.
This command should be used only with the internal modulation source (PWM:SOURce
INTernal).
SOURce<n>:MOD:PWM:INTernal:FUNCtion SINusoid|SQUare|RAMP
SOURce<n>:MOD:PWM:INTernal:FUNCtion?
Selects shape of the internal modulating waveform.
Parameter
Typical Return
SINusoid|SQUare|RAMP, default
SINusoid
SINusoid, SQUare, or RAMP
Select a square wave as the modulating waveform shape:
SOURce1:MOD:PM:INTernal:FUNCtion SQUare
This command should be used only with the internal modulation source (PWM:SOURce
INTernal).
SOURce<n>:MOD:PWM:SOURce INTernal|EXTernal
SOURce<n>:MOD:PWM:SOURce?
Select the source of the modulating signal.
Parameter
Typical Return
INTernal|EXTernal, default INTernal
INTernal, default EXTernal
Select external modulation source:: SOURce1:MOD:FM:SOURce EXTernal
5.2.23 ROSCillatorSubsystem
The ROSCillator subsystem controls use of the 10 MHz reference oscillator and external reference
oscillator input. The reference oscillator is the primary clock for all waveform synthesis. All
waveforms are phase-locked to the reference oscillator, which therefore controls output signal
frequency and phase.
ROSCillator:SOURce - selects internal or external reference oscillator source
