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.

  • cdbl.png RBW (Hz) —

    RBW specifies the bandwidth, in Hz, of the resolution bandwidth (RBW) filter used to measure the signal. The default value is 100 kHz.

  • ci32.png —

    RBW Filter Type specifies the shape of the digital RBW filter. The default value is None.

    None (5)

    The measurement does not use any RBW filtering.
    Gaussian (1)

    The RBW filter has a Gaussian response.
    Flat (2)

    The RBW filter has a flat response.
    RRC (6)

    The RRC filter with the roll-off specified by RRC Alpha parameter is used as the RBW filter.

  • cdbl.png RRC Alpha —

    RRC Alpha specifies the roll-off factor for the root-raised-cosine (RRC) filter. The default value is 0.1.

  • 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.
