► Traditional setup

− System calibration required to compensate

− Frequency dependent antenna gain

− Cable loss

− Mismatch (high contributor to measurement uncertainty)

► Benefits of the NRPM OTA solution

− Fully calibrated measurement system

− Compensated antenna gain

− No RF cables → no RF losses

− No adapters → no mismatch
