The Anritsu 69255A is a synthesized signal generator delivering precise continuous-wave (CW) output from 0.05 GHz to 26.5 GHz. Engineered for telecommunications, defense, and RF laboratory applications, it provides stable frequency generation with 1 kHz resolution and fast switching times suitable for automated test systems. The instrument supports multiple sweep modes, modulation capabilities, and can store up to 1000 non-sequential frequencies for phase-locked step sequencing via GPIB.
