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

Syntax

Namespace: NationalInstruments.RFmx.WlanMX

public int FetchChainRmsEvmPerSubcarrierMeanTrace(string selectorString, double timeout, ref AnalogWaveform< float > chainRmsEvmPerSubcarrierMean)

Parameters

NameTypeDescription
selectorStringstring

Specifies a selector string comprising of the result name, segment number, and chain number. If you do not specify the result name, the default result instance is used. Example:
"segment0/chain0"
"result::r1/segment0/chain0"
You can use the BuildChainString(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.

chainRmsEvmPerSubcarrierMeanref AnalogWaveform< float >

Upon return, contains the chain RMS EVM per subcarrier trace.

Returns

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