Fetches the primary synchronization signal (PSS) EVM and secondary synchronization signal (SSS) EVM.

Use "carrier<k>" or "subblock<n>/carrier<k>" as the selector string to read results from this VI.

Inputs/Outputs

  • cstr.png Selector String —

    Selector String specifies a selector string comprising of the signal name, result name, subblock number, and carrier 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/carrier0".

    Example:

    "subblock0/carrier0"

    "signal::sig1/subblock0/carrier0"

    "result::r1/subblock0/carrier0"

    "signal::sig1/result::r1/subblock0/carrier0"

    You can use the RFmxLTE Build Carrier 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 Mean RMS PSS EVM (% or dB) —

    Mean RMS PSS EVM returns the mean value of RMS EVMs calculated on PSS channel over the slots specified by the ModAcc Meas Length property. When you set the ModAcc EVM Unit property to Percentage, the measurement is returned in percentage. When you set the ModAcc EVM Unit property to dB, the measurement is returned in dB.

  • idbl.png Mean RMS SSS EVM (% or dB) —

    Mean RMS SSS EVM returns the mean value of RMS EVMs calculated on SSS channel over the slots specified by the ModAcc Meas Length property. When you set the ModAcc EVM Unit property to Percentage, the measurement is returned in percentage. When you set the ModAcc EVM Unit property to dB, the measurement is returned in dB.

  • ierrcodeclst.png error out —

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