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

Syntax
public int GetMeanRmsEvm( string selectorString, out double value )
Public Function GetMeanRmsEvm ( 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 EVM values for a QPSK signal. This value is expressed as a percentage. This value is obtained by averaging the RMS EVMs over all averaging iterations. The number of acquisitions is specified by the value of the SetAveragingCount(String, Int32) method. The EVM of a chip is the magnitude of the vector difference between the received chip and the ideal chip. The RMS EVM 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 QevmResultsMeanRmsEvm attribute.
