RFmxInstr Configure RF Attenuation VI

Selector String specifies a Selector String comprising of the signal name. You do not need to use a selector string, if you want to configure this parameter for all signal instances.

Example:

"signal::sig1"

You can use the personality specific Build String VI to build the selector string.

Instrument Handle In identifies the instrument session. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI or the RFmxInstr Initialize NIRFSA (Array) VI.

RF Attenuation Auto specifies whether RFmx computes the RF attenuation.

If you set this parameter to True, RFmx automatically chooses an attenuation setting based on the reference level configured on the personality.

The default value is True.

RF Attenuation specifies the nominal attenuation setting for all attenuators before the first mixer in the RF signal chain. This value is expressed in dB.

If you set the RF Attenuation Auto parameter to True, RFmx chooses an attenuation setting automatically.

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

Instrument Handle Out passes a reference of the instrument session to the next VI.

error out contains error information. This output provides standard error out functionality.
