The Anritsu / Wiltron 68369B Synthesized Signal Generator is a microprocessor-based, synthesized signal sources with high resolution phase-lock capability. It generates both discrete CW frequencies and broad (full range) and narrow band sweeps across the frequency range of 10 MHz to 40 GHz. All functions of the signal generator is fully controllable locally from the front panel or remotely (except for power on/standby) via the IEEE-488 General Purpose Interface Bus (GPIB).
