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

Averaging Enabled specifies whether to enable averaging for the measurement. The default value is False.

False (0)

The measurement is performed on a single acquisition.

True (1)

The measurement uses the value of the Averaging Count parameter to calculate the number of acquisitions over which the measurement is averaged.

Averaging Count specifies the number of acquisitions used for averaging when you set the Averaging Enabled parameter to True. The default value is 10.

Averaging Type specifies the averaging type for averaging multiple spectrum acquisitions. The averaged spectrum is used for the measurement. Refer to the Averaging section of the Spectral Measurements topic for more information about averaging types. The default value is RMS.

RMS (0)

The power spectrum is linearly averaged. RMS averaging reduces signal fluctuations but not the noise floor.

Log (1)

The power spectrum is averaged in a logarithmic scale.

Scalar (2)

The square root of the power spectrum is averaged.

Max (3)

The peak power in the spectrum at each frequency bin is retained from one acquisition to the next.

Min (4)

The least power in the spectrum at each frequency bin is retained from one acquisition to the next.

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.
