Fetches the common pilot error magnitude and phase traces.

Use "segment<n>" 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, and segment number. If you do not specify the signal name, the default signal instance is used. The default value is "segment0".

    Example:

    "segment0"

    "signal::sig1/segment0"

    "result::r1/segment0"

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

    You can use the RFmxWLAN Build Segment 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.

  • icclst.png Common Pilot Error Magnitude —

    Common Pilot Error Magnitude returns the common pilot error magnitude trace. Common pilot error for an OFDM symbol is the correlation of the received pilot subcarrier BPSK symbols with their ideal values. This trace represents the magnitude of the common pilot error for each OFDM symbol.

  • idbl.png x0 —

    x0 returns the starting OFDM symbol index corresponding to the value of OFDMModAcc Meas Offset property.

  • idbl.png dx —

    dx returns the OFDM symbol increment value. This value is always equal to 1.

  • i1dsgl.png y —

    y returns an array of magnitude of the common pilot error for each OFDM symbol.

  • icclst.png Common Pilot Error Phase (deg) —

    Common Pilot Error Phase returns the common pilot error phase trace. Common pilot error for an OFDM symbol is the correlation of the received pilot subcarrier BPSK symbols with their ideal values. This trace represents the phase of the common pilot error for each OFDM symbol.

  • idbl.png x0 —

    x0 returns the starting OFDM symbol index corresponding to the value of OFDMModAcc Meas Offset property.

  • idbl.png dx —

    dx returns the OFDM symbol increment value. This value is always equal to 1.

  • i1dsgl.png y —

    y returns an array of phase of the common pilot error for each OFDM symbol. This value is expressed in degrees.

  • ierrcodeclst.png error out —

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