5-56. Fluctuating Harmonics Phenomenon
SOURce:PHASe<x>:VOLTage:FHARmonics:STATe(?) <bool>{OFF|ON|0|1}
This command turns the specified phase’s voltage 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 the phase’s voltage harmonics.
• OFF or 0 will disable fluctuation of the phase’s voltage 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>:VOLTage:FHARmonics:CLEar
This command clears the modulation of harmonics associated with this phase's voltage. It
does not have a query form.
SOURce:PHASe<x>:VOLTage:FHARmonics:FLUCtuate<y>(?)<bool>{OFF|ON|0|1}
This command turns on/off the fluctuation of harmonic y on the Voltage channel of Phase x.
The query command will return 1 if the specified harmonic is being fluctuated, or 0 if the
specified harmonic is not being fluctuated.
SOURce:PHASe<x>:VOLTage:FHARmonics:ALL?
This query allows all the active harmonics to return their fluctuation state as a comma
delimited string. The comma separated string will contain a value for each harmonic.
Inactive harmonics will always cause 0 to be returned.
SOURce:PHASe<x>:VOLTage:FHARmonics:MODulation <dnpd>,<dnpd>
This command sets the specified phase’s voltage channel fluctuating harmonics modulation
parameters. The first parameter is the modulation depth (expressed as a percentage of the
voltage waveform RMS amplitude). The second parameter is the required modulation
frequency (expressed in Hertz).
SOURce:PHASe<x>:VOLTage:FHARmonics:MODulation? [<cpd>{DEPTh | FREQuency}]
This query returns the modulation depth and frequency for the Voltage channel of the
specified phase. Add the appropriate optional parameter to query just one of these values.

<cpd>{RECTangular|SINusoidal|SQUare}
