ESG Family Signal Generators Programming Commands and Examples
:PULM Subsystem
Internal Pulse Modulation Source Rate
:PULM:INTernal[1]:FREQuency <val><unit>
:PULM:INTernal[1]:FREQuency?
This command sets the rate of the internal squarewave pulse modulation source. The
choices for the variables <val> and <unit> range from 0.1 Hz (minimum) to 50 kHz
(maximum) if the internal waveform is Sine wave. For all other waveforms, the maximum
internal amplitude modulation rate is 10 kHz.
*RST Value: 400.0 Hz
Internal Pulse Waveform Configuration
:PULM:INTernal[1]:FUNCtion:SHAPe SQUare|PULSe
:PULM:INTernal[1]:FUNCtion:SHAPe?
This command toggles the modulation waveform of the internal pulse modulation source
between squarewave and variable pulse width wave. The choices are Square and Pulse.
*RST Value: Pulse
Pulse Modulation Source
:PULM:SOURce INT|EXT2
:PULM:SOURce?
This command sets the source that will generate the pulse modulation. The choices are
Internal Square, Internal Pulse, or External Source 2.
*RST Value: Internal Square
Pulse Modulation State
:PULM:STATe ON|OFF|1|0
:PULM:STATe?
This command sets the operating state of the pulse modulation source. The choices are On
(1) or Off (0).
*RST Value: Off
