Specifies whether RFmx compensates for the instrument noise while performing the measurement when you set the Spectrum Noise Cal Mode property to Auto, or when you set the Spectrum Noise Cal Mode property to Manual and Spectrum Meas Mode to Measure. Refer to the Noise Compensation Algorithm topic for more information.

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is False.

Supported Devices: PXIe-5663/5665/5668, PXIe-5830/5831/5832

Remarks

The following table lists the characteristics of this property.

Short Name Spectrum Noise Comp Enabled
Data type ci32.png
Permissions Read/Write
High-level VIs N/A
Resettable Yes
False 0

Disables compensation of the spectrum for the noise floor of the signal analyzer.
True 1

Enables compensation of the spectrum for the noise floor of the signal analyzer. The noise floor of the signal analyzer is measured for the RF path used by the Spectrum measurement and cached for future use. If signal analyzer or measurement parameters change, noise floors are measured again.
