Inputs/Outputs

  • cstr.png Selector String

    Selector String specifies a selector string comprising of the signal name, result name, and subblock 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 "subblock0".

    Example:

    "subblock0"

    "signal::sig1/subblock0"

    "result::r1/subblock0"

    "signal::sig1/result::r1/subblock0"

    You can use the RFmxNR Build Subblock 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.

  • idbl.png Subblock Power (dBm)

    Subblock Power returns the sum of powers of all the frequency bins over the integration bandwidth of the subblock. This includes the power in inter-carrier gaps within a subblock. This value is expressed in dBm.

  • idbl.png Integration Bandwidth (Hz)

    Integration Bandwidth returns the integration bandwidth used in calculating the power of the subblock. Integration bandwidth is the span from left edge of the leftmost carrier to the right edge of the rightmost carrier within a subblock. This value is expressed in Hz.

  • idbl.png Frequency (Hz)

    Frequency returns the absolute center frequency of the subblock. This value is the center of the subblock integration bandwidth. This value is expressed in Hz.

  • ierrcodeclst.png error out

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