Returns the net signal gain for the device at the current RFmx settings and temperature. RFmx scales the acquired I/Q and spectrum data from the digitizer using the value of this property.

For a vector signal analyzer (VSA), the system is defined as the RF downconverter for all interfaces between the RF IN connector on the RF downconverter front panel and the IF IN connector on the digitizer front panel. For a spectrum monitoring receiver, the system is defined as the RF preselector, RF downconverter, and IF conditioning modules including all interfaces between the RF IN connector on the RF preselector module front panel and the IF IN connector on the digitizer front panel.

Note This property is not supported on a MIMO session.

You do not need to use a selector string if you want to configure this property for all signal instances. Specify the signal name in the selector string if you want to configure or read that signal instance. Refer to the Selector Strings topic for information about the string syntax.

The default value is N/A.

Supported devices: PXIe-5644/5645/5646, PXIe-5663/5663E/5665/5668, PXIe-5830/5831/5832/5840/5841/5842/5860
