: ACDC? Query the rms voltage
: DC? Query the DC voltage
This command lets the user get measurement data from the AC source. Two measurement
commands are available: MEASure and FETCh. MEASure triggers the acquisition of new
data before returning data. FETCh returns the previously acquired data from measurement
buffer.
FETCh [ : SCALar] : CURRent : AC?
MEASure [ : SCALar] : CURRent : AC?
Description : These queries return the rms current which is being output at
the output terminal.
Query Syntax : FETCh : CURRent : AC?, MEASure : CURRent : AC?
Return Parameters : <NR2>
FETCh [ : SCALar] : CURRent : AMPLitude : MAXimum?
MEASure [ : SCALar] : CURRent : AMPLitude : MAXimum?
Description : These queries return the absolute value of peak current.
Query Syntax : FETCh : CURRent : AMPLitude : MAXimum?,
MEASure : CURRent : AMPLitude : MAXimum?
Return Parameters : <NR2>
FETCh [ : SCALar] : CURRent : CREStfactor?
MEASure [ : SCALar] : CURRent : CREStfactor?
Description : These queries return the output current crest factor. It is the
ratio of peak output current to rms output current.
Query Syntax : FETCh : CURRent : CREStfactor?
MEASure : CURRent : CREStfactor?
Return Parameters : <NR2>
FETCh [ : SCALar] : FREQuency?
MEASure [ : SCALar] : FREQuency?
Description : These queries return the output frequency in Hertz.
Query Syntax : FETCh : FREQuency?
MEASure : FREQuency?
Return Parameters : <NR2>
FETCh [ : SCALar] : POWer : AC [ : REAL] ?
MEASure [ : SCALar] : POWer : AC [ : REAL] ?
Description : These queries return the true power which is being output at
output terminals in watts.
Query Syntax : FETCh : POWer : AC?
MEASure : POWer : AC?
Return Parameters : <NR2>
FETCh [ : SCALar] : POWer : AC : APParent?
MEASure [ : SCALar] : POWer : AC : APParent?
Description : These queries return the apparent power which is being output
at output terminals in volt-amperes.
Query Syntax : FETCh : POWer : AC : APParent?
MEASure : POWer : AC : APParent?
Return Parameters : <NR2>
