RFmx
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.

Syntax
public int FetchPeakCde( string selectorString, double timeout, out double peakCde, out int peakCdeWalshCodeNumber, out RFmxCdma2kMXModAccPeakCdeBranch peakCdeBranch )
Public Function FetchPeakCde ( selectorString As String, timeout As Double, <OutAttribute> ByRef peakCde As Double, <OutAttribute> ByRef peakCdeWalshCodeNumber As Integer, <OutAttribute> ByRef peakCdeBranch As RFmxCdma2kMXModAccPeakCdeBranch ) As Integer
Parameters
- 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 Double
-
Upon return, contains the maximum value among the code domain errors. This value is expressed in dB.
- peakCdeWalshCodeNumber Int32
-
Upon return, contains the code number of the channel corresponding to the peakCDE value.
- peakCdeBranch RFmxCdma2kMXModAccPeakCdeBranch
-
Upon return, contains the branch of the channel corresponding to the peakCDE value.
Return Value
Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
