The Anritsu 68247B is a synthesized signal generator delivering phase-locked RF sources from 10 MHz to 20 GHz for RF device testing, subsystem characterization, and ATE applications. Built for commercial telecom, aerospace, and defense environments, this instrument combines ultra-low phase noise with high spectral purity across its full band. It supports discrete CW generation, broadband and narrowband sweeps, and complex modulation scenarios—making it ideal for local oscillator replacement, component analysis, and signal simulation.
