The Agilent HP 8341B is a synthesized sweeper signal generator delivering stable, precise RF and microwave signals across 10 MHz to 20 GHz. Built for receiver testing, component characterization, and automated test system integration, this instrument combines synthesized output with excellent spectral purity and frequency accuracy. Its analog sweep capability spans 45 ms to 200 sec across the full frequency range, supported by four overlapping frequency bands that minimize bandswitch points during sweep execution. The generator provides AM, FM, and pulse modulation for complex signal simulation and analysis.
