Issue Details

I generate signal in RFmx Waveform Creator for WLAN has 68 symbols (No of Data Symbols). Default value for configuration ModAcc(WLAN) "Max Meas Length(symbols)" is 16. But when increasing this value , the indicator for "EVM vs. Symbol " can only show 18 symbols (Symbol Index). Screenshot as below.

 

How to get all the symbols using RFIC SFP? 

 

 

Solution

User needs to configure both Measurement Length and maxMeasurementLength(Symbol) parameters. If user wants to view the full symbols in the measurement, the Measurement Length should match with the waveform burst length, which was created in the RFmx WLAN Waveform creator.

 

We can find these details in the RFmx WLAN help document, which explains the functionality of these parameters.

RFIC: Measurement Length --> RFmx WLAN: OFDMModacc: Acquisition Length(s)

RFIC: MaxMeasurement Length (symbol) -- > RFmxWLAN: OFDMModacc: maxMeasurementLength(symbol)
