Returns the maximum value among the code domain errors (CDEs), in dB.
This method calculates the CDEs by projecting the descrambled error vector onto the code domain at a specific spreading factor.
The CDE for every code with a specific spreading factor is defined as the ratio of the mean power of the projection onto that code to the mean power of the composite reference waveform. A fixed spreading factor of 32 is used.
This method computes the CDEs separately for I and Q branches.

Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Specifies a selector string comprising of the result name. If you do not specify the result name, the default result instance is used. |
| timeout | double | 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 method waits until the measurement is complete. |
| peakCde | out double | Upon return, contains the maximum value among the code domain errors. This value is expressed in dB. |
| peakCdeWalshCodeNumber | out int | Upon return, contains the code number of the channel corresponding to the peakCDE value. |
| peakCdeBranch | out RFmxCdma2kMXModAccPeakCdeBranch | Upon return, contains the branch of the channel corresponding to the peakCDE value. |
Returns
Returns the status code of this method. The status code either indicates success or describes a warning condition.
