SOURce:PHASe<x>:CURRent:MHARmonics:HARMonic<y>:AMPLitude?
This query returns the amplitude (in the presently selected Current amplitude Units of the
specified harmonic on the specified phase.
SOURce:PHASe<x>:CURRent:MHARmonics:HARMonic<y>:PANGle?
This query returns the phase angle (in the presently selected phase angle units) of the
specified harmonic on the specified phase.
SOURce:PHASe<x>:CURRent:MHARmonic:ALL? [<cpd>{ AMPLitude |
PANGle }]
This query returns the amplitude (in the presently selected current amplitude units), and
phase angle (in the presently selected phase angle units) of all harmonics on the specified
phase as a comma separated list. Add the appropriate optional parameter to query just one of
these values.
Example, suppose we have the following:
Harmonic Amplitude Phase
1 2.5 A 90.0 deg
2 0.0 V 0.0 deg
3 1.09 A 0.0 deg
4 0.0 V 0.0 deg
5 0.25 A 165.0 deg
Expected responses:

5-70. Fluctuating Harmonics Phenomenon
SOURce:PHASe<x>:CURRent:FHARmonics:STATe(?) <bool>{OFF|ON|0|1}
This command turns the specified phase’s current channel fluctuating harmonics
phenomena on and off. If no harmonics are currently selected for the specified Phase, a
suitable error message will be reported indicating that some harmonics need to be activated
before fluctuation can be applied.
• ON or 1 will enable fluctuation of this phase’s current harmonics.
• OFF or 0 will disable fluctuation of this phase’s current harmonics.
The query command will return 1 if the specified fluctuation is being applied, or 0 if the
specified fluctuation is inactive.
SOURce:PHASe<x>:CURRent:FHARmonics:CLEar
This command clears the modulation of harmonics associated with this phase's current. It
does not have a query form.
SOURce:PHASe<x>:CURRent:FHARmonics:FLUCtuate<y>(?)<bool>{OFF|ON|0|1}
This command turns on/off the fluctuation of harmonic y on the Current channel of Phase x.
