The Gigatronics GT9000S is a synthesized Microwave Sweeper with a sweep capability over a range of synthesized microwave frequencies and power levels in a variety of modulation modes. The GT9000S can generate output signals over a frequency range of 10 MHz to 26 GHz. The frequency range is dependent on the model number. The RF output can be fixed (CW), swept, amplitude, pulse, or externally frequency modulated.
