RFmx
Gets the mean of the RMS phase error values for a QPSK signal. This value is expressed as a percentage.This value is obtained by averaging the RMS phase errors obtained over all averaging acquisitions. The number of acquisitions is specified by the value of the SetAveragingCount(String, Int32) method. The phase error of a chip is the difference in the phases of the received chip and the ideal chip. The RMS phase error is obtained from all the chips in the measurement interval.

Syntax
public int GetMeanPhaseError( string selectorString, out double value )
Public Function GetMeanPhaseError ( selectorString As String, <OutAttribute> ByRef value As Double ) As Integer
Parameters
- selectorString String
-
Specifies the result name.
Example: ""
"result::r1"
You can use the BuildResultString(String) method to build the selectorString. - value Double
- Upon return, contains the mean of the RMS phase error values for a QPSK signal. This value is expressed as a percentage.This value is obtained by averaging the RMS phase errors obtained over all averaging acquisitions. The number of acquisitions is specified by the value of the SetAveragingCount(String, Int32) method. The phase error of a chip is the difference in the phases of the received chip and the ideal chip. The RMS phase error is obtained from all the chips in the measurement interval.
Return Value
Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
Remarks
This method gets the value of QevmResultsMeanPhaseError attribute.
