Returns the measurement status and margin from the limit line measured in the lower offset segment. Use "offset<n>" as the selector string to read parameters from this VI.

Inputs/Outputs

  • cstr.png Selector String —

    Selector String specifies a selector string comprising of the signal name, result name, and offset 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.

    Examples:

    "offset0"

    "signal::sig1/offset0"

    "result::r1/offset0"

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

    You can use the RFmxEVDO 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.

  • 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.

  • idbl.png Margin Relative Power (dB) —

    Margin Relative Power returns the power at which the margin occurred in the lower (negative) offset segment relative to the integrated power of the reference carrier. This value is expressed in dB.

  • idbl.png Margin Absolute Power (dBm) —

    Margin Absolute Power returns the power at which the margin occurred in the lower (negative) offset segment. This value is expressed in dBm.

  • igenclassrntag.png Instrument Handle Out —

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

  • ii32.png Measurement Status —

    Measurement Status indicates the lower offset measurement status.

    Fail (0) the signal exceeds the limits given by 3GPP2 C.S0033-D v2.0 tables 4.4.1.3-1 ff.
    Pass (1) The signal did not exceed the spectrum emission limits.
  • idbl.png Margin (dB) —

    Margin returns the margin. This value is expressed in dB. Margin is defined as the minimum distance between the spectrum and the limit mask.

  • idbl.png Margin Frequency (Hz) —

    Margin Frequency returns the frequency at which the margin occurred in the lower (negative) offset. This value is expressed in Hz.

  • ierrcodeclst.png error out —

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