Sequoia Series 59
MEASure:CURRent:CREStfactor?
FETCh:CURRent:CREStfactor?
Phase Selectable
These queries return the output current crest factor. This is the ratio of peak output current to rms
output current.
Query Syntax MEASure[:SCALar]:CURRent:CREStfactor?
FETCh[:SCALar]:CURRent:CREStfactor?
Parameters None
Examples MEAS:CURR:CRES? FETC:CURR:CRES?
Returned Parameters <NR2>
Related Commands INST:NSEL
MEASure:CURRent:HARMonic?
FETCh:CURRent:HARMonic?
Phase Selectable
These queries return the rms amplitude of the Nth harmonic of output current. 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 frequencies can be queried up to the fundamental
measurement bandwidth of the measurement system:
10.4 microseconds for single-phase mode and 31.2 microseconds for three-phase mode.
Thus, the maximum harmonic that can be measured is dependent on the output frequency. Any
harmonics that represent frequencies greater than above frequencies are returned as 0.
