IEEE 802.11be: Prepare for Wi-Fi 7 With the Correct Software Boot Camp | Lesson 4 of 11| Understand how to use Keysight's PathWave software to perform demodulation and Error Vector Magnitude (EVM) analysis on Wi-Fi 7 signals. Demodulation is the process of converting a modulated signal back to its original form, and EVM is a measure of the quality of the demodulation process.
