- In this tutorial, I generate a 100 Msym/s 64QAM custom digital modulation signal on the Rohde & Schwarz SMW200A vector signal generator and Rohde & Schwarz FSW spectrum and vector signal analyzer.
Key measurements: EVM and bit error rate, compensation and equalization to improve these, and degradation due to poor signal to noise ratio via the addition of additive white gaussian noise.
