The Anritsu 68369B is a synthesized microwave sweep and signal generator belonging to the 68B Series. Covering a wide frequency range from 10 MHz to 40 GHz, it is designed for local oscillator substitution, component analysis, and automated test equipment (ATE) systems. It features ultra-low single-sideband (SSB) phase noise, precise power output control from -125 dBm to +17 dBm, and comprehensive internal modulation capabilities including AM, FM, phase, and pulse modulation.
