Measuring the BER and the EVM for Signals with Low SNR
Signals with low signal-to-noise ratios (SNR) often cause bit errors during demodulation, so that modulation
accuracy values such as the error vector magnitude (EVM) may not be determined correctly.
This application sheet describes:
- The significance of the Bit Error Rate (BER) parameter for signal analysis
- How the R&S FSW VSA application calculates the BER and determines bit errors
- How this knowledge can be used to obtain correct modulation accuracy results
