Fetches the absolute and relative powers measured in the offset channel for the ACP measurement. The relative powers are measured relative to the power reference carrier.

Use "offset<n>" as the selector string to configure 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. The default value is "" (empty string).

    Example:

    "offset0"

    "signal::sig1/offset0"

    "result::r1/offset0"

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

    You can use the RFmxWCDMA 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 time for which the VI waits for the measurement to complete. This value is expressed in seconds. 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 Lower Absolute Power (dBm) —

    Lower Absolute Power returns the lower offset channel power.

    The lower offset channel power is the integrated power of the RRC-filtered signal at the lower offset frequency. The RRC filter uses a bandwidth of 3.84 MHz with a roll-off factor of 0.22.

  • idbl.png Upper Absolute Power (dBm) —

    Upper Absolute Power returns the upper offset channel power.

    The upper offset channel power is the integrated power of the RRC-filtered signal at the upper offset frequency. The RRC filter uses a bandwidth of 3.84 MHz with a roll-off factor of 0.22.

  • igenclassrntag.png Instrument Handle Out —

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

  • idbl.png Lower Relative Power (dB) —

    Lower Relative Power returns the offset channel power measured relative to the power of the carrier(s) that you specify in the ACP Offset Pwr Ref Carrier property.

    This value is expressed in dB.

  • idbl.png Upper Relative Power (dB) —

    Upper Relative Power returns the upper offset channel power measured relative to the power of the carrier(s) that you specify in the ACP Offset Pwr Ref Carrier property. This value is expressed in dB.

  • ierrcodeclst.png error out —

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