Inputs/Outputs

  • cstr.png Selector String —

    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 value is "" (empty string).

    Example:

    ""

    "signal::sig1"

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

  • cgenclassrntag.png Instrument Handle In —

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

  • ci32.png External Preamp Present —

    External Preamp PresentSpecifies if an external preamplifier is present in the signal path.

    False (0)

    No external preamplifier present in the signal path.
    True (1)

    An external preamplifier is present in the signal path.
  • cpath.png External Preamp Gain S2P File Path —

    External Preamp Gain S2P File Pathspecifies the path to the S2P file that contains DUT S-Parameters for the specified port.

  • ci32.png External Preamp Gain S-Parameter Orientation —

    External Preamp Gain S-Parameter Orientationspecifies the orientation of the data in the S-parameter table relative to the port you specify. The default value is Port1 Towards DUT.

    Port1 Towards DUT (0)

    Port 1 of the S2P is oriented towards the DUT.
    Port2 Towards DUT (1)

    Port 2 of the S2P is oriented towards the DUT.
  • 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 of your RFmx session to the next VI.

  • ierrcodeclst.png error out —

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