Agilent 6834B Only
These queries return an array of harmonic phases of output current of the neutral output terminal in
degrees, referenced to the positive zero crossing of the fundamental component.
The first value returned is the dc component (always returned as 0 degrees phase) , the second value is
the fundamental frequency, and so on up to the 50th harmonic. Harmonic orders can be measured 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.

These queries return an array containing the instantaneous output voltage in volts.
The output voltage and current are digitized whenever a measure command is given or whenever an
acquire trigger occurs. If digitization is caused by a measure command, the time interval between samples
is determined by the output frequency. For frequencies greater than 45Hz, the time interval is 25
microseconds. If digitization is caused by an acquire trigger, the time interval is set by
SENSe:SWEep:TINTerval, and the position of the trigger relative to the beginning of the data buffer is
determined by SENSe:SWEep:OFFSet:POINts.
