When measuring base station transmitter signal quality, you need to address high-frequency and wide-bandwidth testing challenges, such as in millimeter-wave (mmWave) applications, that make the signal's quality susceptible to impairments. The error vector magnitude (EVM) measurement is a critical signal analysis metric to assess the performance of your 5G private network transmitted signal quality from the base station. Design your 5G private network signal analysis test system to address excessive path loss, wideband noise, and frequency errors, which contribute to signal quality distortion, phase noise, and modulation errors when measuring error vector magnitude.

Using a low-noise amplifier (LNA) at the front-end of the signal analyzer (or spectrum analyzer) reduces the system noise figure with or without the internal preamplifier to optimize the mixer's input level. The two-stage gain optimizes the measurements at low input levels to reduce the noise and provide the best 5G private network signal analysis performance while balancing noise and distortion. This solution is ideal for 5G NR FR1 and FR2 applications and ensures accurate and reliable signal quality measurement in 5G private network base station transmitters.

Characterizing Signal Quality: Error Vector Magnitude (EVM)

  • The error vector is the vector difference between the I-Q signal and the measured signal at a given time
  • Impairments: in-phase and quadrature (I-Q) impairments, phase noise, linear compression (AM to AM), nonlinear compression (AM to PM), frequency errors
