The Model 600 is a very useful and extremely versatile instrument. It is used to synthesize a range of microwave frequencies at a variety of power levels and in a variety of modulation modes. It is capable of generating output signals in the range of 10-18 GHz (1 MHz resolution) with output power levels from +10 to -110 dBm (0.1 dB resolution). The RF output can be internally or externally modulated in AM (10 Hz-10 kHz), FM (10 Hz-1 MHz), and Pulse (10 Hz-1 MHz) modulation modes. Separate displays are provided for frequency, modulation, and output level for setup and monitoring of output conditions.
