The HP/Agilent 83752A Synthesized Sweeper is a precision signal generation instrument covering 0.01 to 20 GHz with maximum leveled output power of +10 dBm. Purpose-built for microwave component characterization, RF system evaluation, and complex signal environment simulation, this synthesizer delivers frequency stability and sweep flexibility across multiple modes. Its 1 Hz frequency resolution, phase-locked ramp sweep capability, and integrated modulation (AM, FM, Pulse) support demanding lab and production test workflows requiring both spectral purity and fast frequency switching.
