60 N5186A MXG and X-Series SA Measurement Guide

5G New Radio (NR) Measurements

5G Waveform, EVM, and ACP Analysis

The MXG enables 5G testing with a low error vector magnitude (EVM). The

MXG has extremely good EVM at high power levels. However, not all signal

analyzers can capture this low value. We will use the X-Series signal analyzer

with the 5G NR X-Series application and the VSA software to observe EVM and

adjacent channel power (ACP).
