Configures arrays of peak threshold and peak excursion criteria which a peak should meet to be classified as a spurious emission (Spur).

Inputs/Outputs

  • cstr.png Selector String —

    Selector String specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. The default value is "" (empty string).

    Example:

    ""

    "signal::sig1"

    You can use the RFmxSpecAn Build Signal String 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.

  • c1ddbl.png Threshold (dBm) —

    Threshold specifies the array of threshold levels, in dBm, above which the measurement detects spurs in the range. The default value is -200.

  • c1ddbl.png Excursion (dB) —

    Excursion specifies the array of peak excursion values, in dB, used to find the spurs in the spectrum. The signal should rise and fall by at least the peak excursion value, above the threshold, to be considered as a spur. The default value is 0.

  • 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.
