The 2550B Microwave Signal Generator delivers industry-best offset phase noise performance, high output power, and fast frequency switching speeds in a single unit. Performance features such as high time base stability, frequency modulation (FM), high-speed pulse/square wave modulation (PM), amplitude modulation (AM) and high leveled output power makes it an excellent test solution for a wide range of CW, modulation, swept frequency, and fast frequency switching applications in both R&D and manufacturing environment.
