Fetches the stream RMS EVM per subcarrier trace for each user. When you set the SetAveragingEnabled(string, RFmxWlanMXOfdmModAccAveragingEnabled) method to True , this method returns the mean of the user stream RMS EVM per subcarrier computed for each averaging count.
Use "user(n)/stream(k)" as the selector string to read results from this method.

Syntax

Namespace: NationalInstruments.RFmx.WlanMX

public int FetchUserStreamRmsEvmPerSubcarrierMeanTrace(string selectorString, double timeout, ref AnalogWaveform< float > userStreamRmsEvmPerSubcarrierMean)

Parameters

NameTypeDescription
selectorStringstring

Specifies a selector string comprising of the result name, user number, and stream number. If you do not specify the result name, the default result instance is used. Example:
"user0/stream0"
"result::r1/user0/stream0"
You can use the BuildStreamString(string, int) method to build the selector string.

timeoutdouble

Specifies the timeout for fetching the specified measurement. 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. This value is expressed in seconds.

userStreamRmsEvmPerSubcarrierMeanref AnalogWaveform< float >

Upon return, contains the stream RMS EVM per subcarrier trace for each user. When you set the Averaging Enabled method to True , this parameter returns the mean of the user stream RMS EVM per subcarrier computed for each averaging count.

Returns

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