Inputs/Outputs

  • cstr.png Selector String —

    Selector String specifies a selector string comprising of the signal name and result name. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used. The default value is "" (empty string).

    Examples:

    ""

    "signal::sig1"

    "result::r1"

    "signal::sig1/result::r1"

    You can use the RFmxCDMA2k 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 Timeout (s) —

    Timeout specifies the timeout for fetching the specified measurement. This value is expressed in seconds. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the VI waits until the measurement is complete. The default value is 10.

  • 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.

  • icclst.png Spectrum (dBm) —

    Spectrum returns the trace of power levels in the spectral domain. This value is expressed in dBm.

  • idbl.png x0 —

    x0 returns the start frequency. This value is expressed in Hz.

  • idbl.png dx —

    dx returns the frequency bin spacing. This value is expressed in Hz.

  • i1dsgl.png y —

    y returns the averaged power measured at each frequency bin. This value is expressed in dBm.

  • ierrcodeclst.png error out —

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