Configures the resolution bandwidth (RBW) filter to be applied on the acquired signal. The bandwidth of the filter specified is applicable for fundamental signal.

Supported devices: PXIe-5665, PXIe-5668

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 acquire the fundamental signal. The default value is 100 kHz.

  • ci32.png —

    RBW Filter Type specifies the shape of the digital RBW filter. The default value is Gaussian.

    None (1)

    The measurement does not use any RBW filtering.
    Gaussian (2)

    An RBW filter with a Gaussian response is applied.
    Flat (3)

    An RBW filter with a flat response is applied.

    RRC (4)

    The measurement uses RRC FIR coefficients for filtering.

  • 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.
