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

Parameters

NameTypeDescription
selectorStringstring

Specifies the result name.
Example: ""
"result::r1"
You can use the BuildResultString(string) method to build the selectorString.

valueout double

Upon return, contains the mean of peak EVMs for a QPSK signal. This value is expressed as a percentage. This value is obtained by averaging the peak EVMs over all averaging acquisitions. The number of acquisitions is specified by the value of the SetAveragingCount(string, int) method.The EVM of a chip is the magnitude of the vector difference between the received chip and the ideal chip. The peak EVM is obtained from all the chips in the measurement interval.

Returns

Returns the status code of this method. The status code either indicates success or describes a warning condition.
