Returns the total absolute and relative powers, peak absolute and relative powers and frequency at peak absolute power of lower offset segment. The relative power is relative to the peak power of the carrier.

Use "segment<n>/chain<k>/offset<l>" 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, segment number, chain number, and offset number. If you do not specify the signal name, the default signal instance is used. The default value is "segment0/chain0/offset0".

    Example:

    "segment0/chain0/offset0"

    "signal::sig1/segment0/chain0/offset0"

    "signal::sig1/result::r1/segment0/chain0/offset0"

    "result::r1/segment0/chain0/offset0"

    You can use the RFmxWLAN Build Offset 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.

  • idbl.png Peak Relative Power (dB) —

    Peak Relative Power returns the peak power of the lower offset, relative to the peak power of the carrier channel. This value is expressed in dBm.

  • idbl.png Peak Frequency (Hz) —

    Peak Frequency returns the frequency at which the peak power occurs in the lower offset. This value is expressed in Hz.

  • igenclassrntag.png Instrument Handle Out —

    Instrument Handle Out passes a reference of your RFmx session to the next VI.

  • idbl.png Total Absolute Power (dBm) —

    Total Absolute Power returns the average power of the lower offset over the bandwidth determined by the offset start and stop frequencies. This value is expressed in dBm.

  • idbl.png Total Relative Power (dB) —

    Total Relative Power returns the average power of the lower offset relative to the peak power of the carrier channel. This value is expressed in dB.

  • idbl.png Peak Absolute Power (dBm) —

    Peak Absolute Power returns the peak power of the lower offset. This value is expressed in dBm.

  • ierrcodeclst.png error out —

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