The Anritsu MG3670B is a digital modulation signal generator designed for developing, testing, and evaluating digital mobile communications equipment. Operating from 300 kHz to 2.25 GHz, the MG3670B features a high-performance integrated quadrature modulator and delivers stable and precise RF signals up to +13 dBm, even under modulation. It supports a dedicated CMOS-level mode for I/Q signal input, covers the CDMA spread spectrum band, and can be expanded using up to eight modulation units and a burst function unit simultaneously.
