► 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
