FETCh/MEASure Query Notes
CURRent:ACDC?
Current, AC+DC (Arms)
This command applies to AC+DC.
CURRent:AMPLitude:MAXimum[:INSTant]?
Peak current (A)
This command applies to all output modes.
CURRent:AMPLitude:MAXimum:HOLD?
Peak AC current held value (A)
This command applies to all output modes.
You can clear the peak value with SENS:CURR:PEAK:CLE .
This returns the maximum peak current since the power-on or
since it was explicitly cleared (SENSe:CURRent:PEAK:CLEar).
The peak current (held value) is not cleared by *RST or
*RCL .
CURRent:CREStfactor?
Crest factor
This command applies to AC, AC+DC, EXT-DC, and EXT-AC.
The crest factor is the AC current divided by the AC peak
current.
The crest factor for sine waves is √2.
FREQuency?
AC output frequency (Hz)
This returns the frequency setting for AC, ACDC, and EXT-AC
coupling, or +9.37 for DC and EXT-DC coupling. The
instrument does not measure frequency.
POWer[:DC]?
Average DC power (W)
This command applies to DC, AC+DC, and EXT-DC.
Set the averaging period using SENS:AVER .
POWer:AC[:REAL]?
AC active power (W)
This command applies to AC, AC+DC, EXT-DC, and EXT-AC.
POWer:AC:APParent?
AC apparent power (VA)
This command applies to AC, AC+DC, EXT-DC, and EXT-AC.
POWer:AC:PFACtor?
AC power factor
This command applies to AC, AC+DC, EXT-DC, and EXT-AC.
The power factor indicates the efficiency degradation caused
by the phase difference between the AC voltage and AC
current.
