Configures the threshold level for the samples that need to be considered for the transmit power (TXP) measurement. Enable the threshold when analyzing burst signals or signals with dead time.

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.

  • ci32.png Threshold Enabled —

    Threshold Enabled specifies whether to enable thresholding of the acquired samples to be used for the measurement. The default value is False.

    False (0)

    All samples are considered for the measurement.
    True (1)

    The samples above the threshold level specified in the Threshold Level parameter are considered for the measurement.

  • cdbl.png Threshold Level (dB or dBm) —

    Threshold Level specifies either the relative or absolute threshold power level based on the value of the Threshold Type parameter. The default value is -20 dB.

  • ci32.png Threshold Type —

    Threshold Type specifies the reference for the power level used for thresholding. The default value is Relative.

    Relative (0)

    The threshold is relative to the peak power, in dB, of the acquired samples.
    Absolute (1)

    The threshold is the absolute power, in dBm.

  • 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.
