Maxwellon TW4203 series RF spectrum analyzer is designed based on the concept “Smaller, lighter, easier” . TW4203 series takes a small desktop space and easy to carry. Most of nowaday RF applications are in this band, like mobile communication (GSM, CDMA, LTE even low frequency 5G), WIFI (2.4GHz), remote control etc, so TW4203 series is a good tool for the test, maintenance, R&D of these applications. Tracking source and CW source provide ability to do complex measurements. For so many functions integrated in one box, TW4203 series also very fits for eduction.
