Performs the enabled measurements on the I/Q complex waveform that you specify in IQ parameter. Call this VI after you configure the signal and measurement properties. You can fetch measurement results using the Fetch VIs or result properties in the property node. Use this VI only if the Recommended Acquisition Type property value is either IQ or IQ or Spectral.

Note Query the Recommended Acquisition Type property from the RFmxInstr Property Node after calling the RFmx Pulse Commit VI.

Inputs/Outputs

  • cstr.png Result Name —

    Result Name specifies the name to be associated with measurement results. Provide a unique name, such as "r1" to enable fetching of multiple measurement results and traces. This input accepts the result name with or without the "result::" prefix. The default value is "" (empty string) which refers to default result instance.

    Example:

    "result::r1"

    "r1"

  • 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"

  • cgenclassrntag.png Instrument Handle In —

    Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI or the RFmxInstr Initialize VI with the option string as "AnalysisOnly=1".

  • ccclst.png IQ —

    IQ specifies the data for a complex waveform including the start, delta, and actual values.

  • cdbl.png x0 —

    x0 specifies the start time of the input y array. This value is expressed in seconds.

  • cdbl.png dx —

    dx specifies the time interval between the samples in the input y array. This value is expressed in seconds. The reciprocal of dx indicates the I/Q rate of the input signal.

  • c1dcsg.png y —

    y specifies an array of complex-valued time domain data. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.

  • cbool.png Reset? —

    Reset? resets measurement averaging. If you enable averaging, set this parameter to TRUE for the first record and FALSE for the subsequent records.

  • 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.

  • istr.png Selector String Out —

    Selector String Out returns the selector string that can be passed to the Selector String parameter on Fetch VIs.

  • ierrcodeclst.png error out —

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