RFmxWCDMA ModAcc Fetch Peak Active CDE VI
- Updated2025-10-13
- 3 minute(s) read
Fetches the peak value among the code domain errors (CDEs) of the active channels, along with the code number, spreading factor, and branch that correspond to this peak value for a carrier in the ModAcc measurement.
Use "carrier<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 carrier 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 "carrier0". Example: "carrier0" "signal::sig1/carrier0" "result::r1/carrier0" "signal::sig1/result::r1/carrier0" You can use the RFmxWCDMA Build Carrier 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 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.
error in (no error)
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Peak Active CDE Branch
—
Peak Active CDE Branch returns the branch of the channel corresponding to the value of the Peak Active CDE parameter for a carrier.
Instrument Handle Out
—
Instrument Handle Out passes a reference to your RFmx session to the next VI.
Peak Active CDE (dB)
—
Peak Active CDE returns the maximum value among the active code domain errors for a carrier. This value is expressed in dB. The active CDEs are computed by despreading the descrambled error vectors corresponding to each active channel with the appropriate active channel codes. The active CDE is defined as the ratio of the mean power of this despread error vector to the mean power of the composite reference waveform.
Peak Active CDE Spreading Factor
—
Peak Active CDE Spreading Factor returns the spreading factor of the channel corresponding to the value of the Peak Active CDE parameter for a carrier.
Peak Active CDE Code
—
Peak Active CDE Code returns the spreading code of the channel corresponding to the value of the Peak Active CDE parameter for a carrier.
error out
—
error out contains error information. This output provides standard error out functionality. |
