WEMA12: Measuring PA Parametric-Level and System-Level EVM for 5G/NR

Presentation Abstract
EVM is often called the "money spec". The question is how to measure it quickly and cost-effectively. We will first present high-performance 5G/NR EVM measurements with NI's latest Vector Signal Transceiver (VST), which offers top-tier performance at a higher cost. Then, we will present measurements with the USRP X410 software-defined radio (SDR), which provides substantial performance at a lower cost. We will demonstrate how both instruments can deliver fast and efficient measurements using the NI RFmx software.
