MEASure:VOLTage:ACDC?

FETCh:VOLTage:ACDC?

Phase Selectable

These queries return the ac+dc rms voltage being sourced at the output terminals.

Query Syntax	MEASure:[SCALar]:VOLTage:ACDC?
	FETCh:[SCALar]:VOLTage:ACDC?
Parameters	None
Examples	MEAS:VOLT:ACDC?	FETC:VOLT:ACDC?
Returned Parameters	<NR3>
Related Commands	MEAS:CURR:ACDC?	MEAS:VOLT?

MEASure:VOLTage:HARMonic?

FETCh:VOLTage:HARMonic?

Phase Selectable

These queries return the rms amplitude of the Nth harmonic of output voltage.

The parameter is the desired harmonic number. Queries sent with a value of 0 return the dc component. A value of 1 returns the fundamental output frequency. Harmonic orders can be queried up to the fundamental measurement bandwidth of the measurement system, which is 12.6kHz. Thus the maximum harmonic that can be measured is dependent on the output frequency. Any harmonics that represent frequencies greater than 12.6kHz are returned as 0.

Query Syntax	MEASure:[SCALar]:VOLTage:HARMonic[:AMPLitude]? <NRf>
	FETCh:[SCALar]:VOLTage:HARMonic[:AMPLitude]? <NRf>
Parameters	0 to 50
Examples	MEAS:VOLT:HARM? 3	FETC:VOLT:HARM? 1
Returned Parameters	<NR3>
