WebJul 24, 2024 · EVM is a major indicator that evaluates the modulation quality of vector signal generators. For example, a high-performance signal generator can provide EVM as low as 0.4% for a 160 MHz 802.11ac signal. Low EVM performance provides more test margin for receiver sensitivity and component characteristics tests. EVM (dB) = 20 log10 (EVM ...

WebSince the power of both constellation symbols is the same for a BPSK system, configure the EVM measurement object to use peak constellation power normalization.
