How to Measure Signal Quality in 5G Private Networks
Measuring EVM for signal quality in 5G private networks
Measuring base station transmitter signal quality requires addressing high-frequency and wide-bandwidth testing challenges, especially in millimeter-wave (mmWave) applications. The test system for the error vector magnitude (EVM) measurement as a critical signal analysis metric, needs to address excessive path loss, wideband noise, and frequency errors, which contribute to signal quality distortion, phase noise, and modulation errors.
The test system needs to include a low-noise amplifier (LNA) at the front-end of the signal analyzer to reduce the system noise figure and optimize the mixer's input level. This makes it an ideal solution for accurate and reliable signal quality measurement in 5G private network base station transmitters, for both 5G new radio (NR) frequency range 1 (FR1) and FR2 applications.
