Chapter5 Harmonic Commands

In commands of harmonics measurement, the range of values for parameter

“value” is zero to fifty. 0 corresponds to DC, 1 corresponds to fundamental

harmonic and 2-50 corresponds to harmonics. The instrument interface should

be under the harmonics function while using the harmonics command to

measure.

MEASure[:SCALar]:HARMonics?

FETCh[:SCALar]:HARMonics?

This command is used to read the harmonic of a phase.
