RFmxEvdoMXModAccResultsFetchUplinkPeakCde Method
Returns the maximum value among the code domain errors (CDEs), in dB.
The CDEs are calculated 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 16 is used.
The CDEs are calculated separately for I and Q branches.

Syntax
public int FetchUplinkPeakCde( string selectorString, double timeout, out double uplinkPeakCde, out int uplinkPeakCdeWalshCodeNumber, out RFmxEvdoMXModAccUplinkPeakCdeBranch uplinkPeakCdeBranch )
Public Function FetchUplinkPeakCde ( selectorString As String, timeout As Double, <OutAttribute> ByRef uplinkPeakCde As Double, <OutAttribute> ByRef uplinkPeakCdeWalshCodeNumber As Integer, <OutAttribute> ByRef uplinkPeakCdeBranch As RFmxEvdoMXModAccUplinkPeakCdeBranch ) As Integer
Parameters
- selectorString
- Type: SystemString
Specifies a selector string comprising of the result name. If you do not specify the result name, the default result instance is used. - timeout
- Type: SystemDouble
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. - uplinkPeakCde
- Type: SystemDouble
Upon return, contains the maximum value among the CDEs. This value is expressed in dB. - uplinkPeakCdeWalshCodeNumber
- Type: SystemInt32
Upon return, contains the code number of the channel corresponding to the uplinkPeakCDE result. - uplinkPeakCdeBranch
- Type: NationalInstruments.RFmx.EvdoMXRFmxEvdoMXModAccUplinkPeakCdeBranch
Upon return, contains the quadrature branch of the peak CDE.
Return Value
Type: Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
