RFmxNR ACP Fetch Component Carrier Measurement (Array) VI
- Updated2025-10-13
- 3 minute(s) read
Returns an array of the absolute and relative powers measured in the component carriers.
Use "subblock<n>" as the selector string to read results from this VI.

Inputs/Outputs
Selector String
—
Selector String specifies a selector string comprising of the signal name, result name, and subblock 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: "subblock0" "signal::sig1/subblock0" "result::r1/subblock0" "signal::sig1/result::r1/subblock0" You can use the RFmxNR Build Subblock String VI to build the selector string.
Instrument Handle In
—
Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI.
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.
error in (no error)
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Instrument Handle Out
—
Instrument Handle Out passes a reference of your RFmx session to the next VI.
Absolute Power (dBm or dBm/Hz)
—
Absolute Power returns an array of the power measured over the integration bandwidth of the component carrier. This value is expressed in dBm. The carrier power is reported in dBm when you set the ACP Pwr Units property to dBm, and in dBm/Hz when you set the ACP Pwr Units property to dBm/Hz.
Relative Power (dB)
—
Relative Power returns an array of the component carrier power relative to its subblock power. This value is expressed in dB.
error out
—
error out contains error information. This output provides standard error out functionality. |
