The Agilent 8340B Synthesized Sweeper generates RF and microwave signals from 10 MHz to 26.5 GHz with synthesized accuracy and rapid sweep performance. Built for component characterization, system simulation, and demanding aerospace, telecommunications, and defense applications, this instrument delivers low phase noise, stable output, and versatile modulation—pulse, AM, FM, and simultaneous combinations—across its full frequency range.
