RFmxLTE Configure RF VI

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 is "" (empty string).

Example:

"signal::sig1"

You can use the RFmxLTE Build Signal String VI to build the selector string.

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

Center Frequency specifies the center frequency of the acquired RF signal for a single carrier. The parameter specifies the reference frequency of the subblock for intra-band carrier aggregation. The default value of this parameter is hardware dependent.

External Attenuation specifies the attenuation of a switch or cable connected to the RF IN connector of the signal analyzer. This value is expressed in dB. For more information about attenuation, refer to the RF Attenuation and Signal Levels topic for your device in the NI RF Vector Signal Analyzers Help. The default value is 0.

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

Instrument Handle Out passes a reference to your RFmx session to the next VI.

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