The 600 is used to synthesize a range of microwave frequencies at a variety of power levels and in a variety of modulation modes. Can generate output signals in the range of 10 MHz-8 GHz (1 MHz resolution) with output power levels from +10 to -110 dBm (0.1 dB resolution) 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 Can be operated manually from the logically laid-out front panel, or under remote computer control via the IEEE-488 interface bus
