In this video, you will learn a new technique to measure EVM, called cross-correlated EVM (ccEVM) using Keysight PXI Vector Transceivers. Cross-Correlated EVM (ccEVM) is a technique used to extend the dynamic range of a receiver for best EVM performance. Two of the same receivers are used to capture and demodulate the same signal independently and perform cross-correlation on the error vectors to cancel out uncorrelated noise added by the receivers, resulting in a much lower EVM. This technique gives you super accurate 5G NR EVM results of the DUT.
