             The 2540B 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.  The 2500B series Microwave Signal Generator utilizes new Advanced Synthesizer Technology that delivers excellent close in phase noise performance of -77dBc @ 100 Hz and -96dBc @ 1KHz and an ultra low phase noise performance of -109 dBc @ 10 kHz and 100 kHz offset on a 10 GHz carrier frequency.  Every 2500B Microwave Signal Generator comes with Giga-tronics Automation Xpress, a PC based software package designed for enhanced user interface and automatic test systems. The Automation Xpress CD includes a full-featured plug-and-play driver and soft front panels to provide the ATE system integrator with everything needed to get up and running fast. A comprehensive LIST mode, Command-Line interpreter with script and loop capability, and GPIB traffic monitoring are just a few of the many features a test system programmer will appreciate when developing and debugging Test Program Sets.  ** Prices are valid in USA only.
