Inputs/Outputs

  • cstr.png Selector String —

    Selector String specifies a selector string comprising of the signal name, result name, segment number, and stream number. 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 "segment0/stream0".

    Example:

    "segment0/stream0"

    "signal::sig1/segment0/stream0"

    "signal::sig1/result::r1/segment0/stream0"

    "result::r1/segment0/stream0"

    You can use the RFmxWLAN Build Stream 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 or the RFmxInstr Initialize NIRFSA (Array) VI.

  • cdbl.png Timeout (s) —

    Timeout specifies the timeout for fetching the specified measurement. 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. This value is expressed in seconds. 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 of your RFmx session to the next VI.

  • i1dcsg.png Reference Data —

    Reference Data Constellation returns the reference QAM symbols for all the data-subcarriers in all the OFDM symbols.

  • ierrcodeclst.png error out —

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