Sequoia Series 199
8.3.2 Interharmonics Subsystem
The following commands are used to enable and generate an interharmonic waveform up to 20% of
the programmed voltage value.
[:SOURce]
:IHARmonics
[:STATe] Enable or disable the interharmonics generator.
:COUPle Couple the interharmonics reference to program volt.
:FREQuency Set the interharmonics frequency.
:REFerence Set the interharmonics reference.
:VOLTage Set the interharmonics output as % of reference.
[:SOURce]:IHARmonics[:STATe]
This command enables the interharmonics generator. This command must be set to the on state
before sending any other command listed in this section.
Command Syntax [:SOURce]:IHARmonics:STATe <boolean>
Parameters <ON|OFF|1|0 >
Examples IHAR ON
Query Syntax IHAR?
Returned Parameters <boolean>
[:SOURce]:IHARmonics:COUPle
If this command is turned on, the reference voltage for the interharmonics is programmed to a value
equal to the AC program value. If the coupling is turned off, the reference voltage must be programmed
to a value between 0 and 250V.
Command Syntax [:SOURce]:IHARmonics:COUPle <boolean>
Parameters <ON|OFF|1|0 >
Examples IHAR:COUP ON
Query Syntax IHAR:COUP?
Returned Parameters <boolean>
[:SOURce]:IHARmonics:FREQuency
This command will program the inter harmonic frequency. This frequency may range from 1Hz to
2400Hz with 1Hz resolution.
Command Syntax [:SOURce]:IHARmonics:FREQuency <NRf>
Parameters <frequency >
Examples IHAR:FREQ 400
Query Syntax IHAR:FREQ?
Returned Parameters <NR1>
