Configures the harmonic frequency, acquisition bandwidth, and acquisition time for the harmonic, when you set the Harm Harmonics Auto Setup Enabled property to False.

Use "harmonic<n>" as the selector string to configure this VI.

Supported devices: PXIe-5665, PXIe-5668

Inputs/Outputs

  • cdbl.png Harmonic Measurement Interval (s) —

    Harmonic Measurement Interval specifies the acquisition time, in seconds, for the harmonic. The default value is 1 ms.

  • cstr.png Selector String —

    Selector String specifies a selector string comprising of the signal name and harmonic number. If you do not specify the signal name, the default signal instance is used. The default value is "harmonic0".

    Example:

    "harmonic0"

    "signal::sig1/harmonic0"

    You can use the RFmxSpecAn Build Harmonic String2 VI to build the selector string.

  • cgenclassrntag.png Instrument Handle In —

    Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI.

  • ci32.png Harmonic Order —

    Harmonic Order specifies the order of the harmonic. The default value is 1.

    Frequency of Nth order harmonic = N * (Frequency of fundamental)

  • cdbl.png Harmonic Bandwidth (Hz) —

    Harmonic Bandwidth specifies the resolution bandwidth, in Hz, for the harmonic. The default value is 100 kHz.

  • ci32.png Harmonic Enabled —

    Harmonic Enabled specifies whether to enable a particular harmonic for measurement. Only the enabled harmonics are used to measure the total harmonic distortion (THD). The default value is True.

    False (0)

    Disables the harmonic for measurement.
    True (1)

    Enables the harmonic for measurement.
  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • igenclassrntag.png Instrument Handle Out —

    Instrument Handle Out passes a reference of your RFmx session to the next VI.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
