Near-Field Antenna Measurement System

Model No. ANM01

It measures in near-field, and converts the result into far-field and aperture distribution.

Features:
‧Substantial contents in analysis and user interface.
‧Fast measurement
ex.) 256x256 points : 30 minutes
(Results depend on the performance of your vector network analyzer.)
