How to Achieve Low EVM and Validate Correct Coding of Physical Channels
5G New Radio (NR) transmission features improve connectivity, network capacity, and data rates. 5G NR achieves high throughput via high-order modulation such as 256QAM. Error vector magnitude (EVM) is the most common method to evaluate the transmitted signal quality from base stations to mobile handsets (user equipment) and vice versa.
To get a meaningful EVM measurement, you must configure the analysis to reflect the intended transmitter channel configuration. This process can be challenging, as there are many knobs to turn and signal configuration parameters to set. Keysight’s PathWave Vector Signal Analysis (VSA) software offers flexibility on many parameters. The following sequence of steps provides best practices on the VSA configuration.
