Chamber Imaging and Range Probing Service



NSI's Chamber Imaging and Range Probing Service will help you insure your test range provides you with the optimum and documented performance for your antenna and RCS measurement facility. NSI engineers will bring a quiet zone field probe on-site to your facility and characterize the amplitude and phase flatness of the quiet zone in your indoor or outdoor far-field range or your Compact Antenna Test Range (CATR) Our analysis capability with the 2D scanned data will also allow the identification of scattering sources and RF leakages.


NSI's engineers have characterized quiet zone performance and performed diagnostic tests on numerous far-field and CATR ranges. See our published technical papers on the subject on our website
