The Wiltron 6719B is a synthesized signal generator designed as a component of the Wiltron 360B Vector Network Analyzer system. It extends measurement capabilities across the 6700B Series frequency range up to 60 GHz. Operating in continuous wave (CW) mode, the 6719B generates nine independent, presettable CW frequencies for precise S-parameter characterization of RF and microwave components including filters, amplifiers, and network devices.
