SOURce1:PWM:INTernal:FUNCtion:EFILe "SAMPLE1"
creates a file named "SAMPLE1" in the mass storage.
This command sets or queries the source of modulating signal of PWM
modulation for the specified channel.
Source
[SOURce[1]]:PWM:SOURce
[SOURce[1]]:PWM:SOURce?
INTernal means that the carrier waveform is modulated with the internal source.
EXTernal means that the carrier waveform is modulated with an external source.
INT|EXT
SOURce1:PWM:SOURce INTernal
sets the source of modulating signal on CH 1 to internal.
This command enables or disables PWM modulation. The query command
returns the state of PWM modulation. You can select only pulse waveform as a
carrier waveform for PWM.
Source
[SOURce[1]]:PWM:STATe
[SOURce[1]]:PWM:STATe?
ON or <NR1>≠0 enables PWM modulation.
OFF or <NR1>=0 disables PWM modulation.
<NR1>
