Specifies the scaling factor applied to the time-domain voltage data in the digitizer. This value is expressed in dB. RFmx does not compensate for the specified digital gain.

You can use this property to account for external gain changes without changing the analog signal path.

Note The PXIe-5644/5645/5646 applies this gain when the data is scaled. The raw data does not include this scaling on these devices.

Default Value : 0 dB

Supported Devices : PXIe-5644/5645/5646, PXIe-5820/5830/5831/5832/5840/5841/5860
