This is the ratio of peakoutput current to rms output current.MEASure:CURRent:HARMonic?FETCh:CURRent:HARMonic?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 0return the DC component. A value of 1 returns the fundamental output frequency.Harmonic orders can be queried up to the fundamental measurement bandwidthof the measurement system, which is 12.6 kHz. Thus the maximum harmonic thatcan be measured is dependent on the output frequency. Any harmonics thatrepresent frequencies greater than 12.6 kHz are returned as 0.Query syntax MEASure:[SCALar]:CURRent:CREStfactor?FETCh:[SCALar]:CURRent:CREStfactor?Parameters NoneExamples MEAS:CURR:CRES?
