The Anritsu MG3633A is a high-performance synthesized signal generator designed for the research, development, and production of radio equipment operating in the quasi-microwave band. Covering a wide frequency range from 10 kHz to 2700 MHz, it offers excellent frequency resolution, fast frequency switching, high signal purity, and a maximum output level of +17 dBm. It features versatile modulation capabilities including AM, FM (with a DC-coupled mode for digital transmissions), and phase modulation (øM), alongside carrier, level, and modulation frequency sweep functions.
