The Anritsu 68145B is a microprocessor-based synthesized sweep generator delivering precise signal generation from 0.5 GHz to 20.0 GHz. It generates discrete CW frequencies, broad full-range sweeps, and narrow-band sweeps with high-resolution phase-lock capability. All operational functions are controllable from the front panel or remotely via IEEE-488 GPIB, except power on/standby control.
