Returns the maximum EVM per symbol trace for all the configured slots. The EVM is obtained by using FFT window position, Delta_C-W/2.
Refer to the LTE Modulation Accuracy (ModAcc) topic for more information.
Use "carrier(k)" or "subblock(n)/carrier(k)" as the selector string to read results from this method.

Syntax

Namespace: NationalInstruments.RFmx.LteMX

public int FetchMaximumEvmLowPerSymbolTrace(string selectorString, double timeout, ref AnalogWaveform< float > maximumEvmLowPerSymbol)

Parameters

NameTypeDescription
selectorStringstring

Specifies a selector string comprising of the result name, subblock number, and carrier number. If you do not specify the result name, the default result instance is used. Example:
"subblock0/carrier0"
"result::r1/subblock0/carrier0"
You can use the BuildCarrierString(string, int) method to build the selector string.

timeoutdouble

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

maximumEvmLowPerSymbolref AnalogWaveform< float >

Upon return, contains the maximum EVM per symbol trace for all the configured slots. The EVM is obtained by using FFT window position, Delta_C-W/2.

Returns

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