  • cgenclassrntag.png Instrument Handle In —

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

  • cdbl.png External Attenuation (dB) —

    External Attenuation specifies the attenuation of a switch or cable connected to the signal analyzer RF IN connector. This value is expressed in dB. The default value is 0 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.

  • cerrcodeclst.png error in (no error) —

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

  • igenclassrntag.png Instrument Handle Out —

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

  • ierrcodeclst.png error out —

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