MEASure:CURRent:AC?
FETCh:CURRent:AC?
Description: These queries return the output ac rms current. It is noted that there are two
kinds of commands to get measurement data. MEASure commands make a
new measurement and return measurement data. FETCh commands return
measured data taken by previous MEASure command. Note that once a new
measurement is made, all new measurement data (V, F, I, P, PF, CF) may be
returned by FETCh command.
Query Syntax: MEASure[:SCALar]:CURRent:AC?
FETCh[:SCALar]:CURRent:AC?
Parameters: None
Return Parameters: <NR2>
Query Example: MEAS:CURR:AC? returns the output ac rms current.
MEASure:CURRent:CREStfactor?
FETCh:CURRent:CREStfactor?
Description: These queries return the output current crest factor.
Query Syntax: MEASure[:SCALar]:CURRent:CREStfactor?
FETCh:[SCALar]:CURRent:CREStfactor?
Parameters: None
Return Parameters: <NR2>
Query Example: MEAS:CURR:CRES? returns the output current crest factor.
MEASure:FREQuency?
FETCh:FREQuency?
Description: These queries return the output frequency.
Query Syntax: MEASure[:SCALar]:FREQuency?
FETCh[:SCALar]:FREQuency?
Parameters: None
Return Parameters: <NR2>
Query Example: MEAS:FREQ? returns the output frequency.
MEASure:POWer:AC?
FETCh:POWer:AC?
Description: These queries return the output real power.
Query Syntax: MEASure[:SCALar]:POWer:AC[:REAL]?
FETCh[:SCALar]:POWer:AC[:REAL]?
Parameters: None
Return Parameters: <NR2>
Query Example: MEAS:POW:AC? returns the output real power.
MEASure:POWer:PFACtor?
FETCh:POWer:PFACtor?
Description: These queries return the output power factor.
Query Syntax: MEASure[:SCALar]:POWer:AC:PFACtor?
FETCh[:SCALar]:POWer:AC:PFACtor?
Parameters: None
