Returns the maximum EVM per symbol trace for all the configured slots. The EVM is obtained by using the FFT window position, Delta_C+W/2.

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.

  • icclst.png Max EVM-High per Symbol (% or dB) —

    Max EVM-High per Symbol returns the maximum EVM per symbol trace for all the configured slots. The EVM is obtained by using FFT window position, Delta_C+W/2.

  • idbl.png x0 —

    x0 returns the starting OFDM symbol position corresponding to the ModAcc Meas Offset property.

  • idbl.png dx —

    dx returns 1 as the value.

  • i1dsgl.png y —

    y returns the array of the maximum EVM per symbol trace for all the configured slots. The EVM is obtained by using FFT window position, Delta_C+W/2.

  • ierrcodeclst.png error out —

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