The HP/Agilent 83620 series comprises synthesized signal generators engineered for RF and microwave testing across component evaluation, receiver characterization, and system verification. These instruments deliver broadband frequency coverage with 1 Hz resolution, low single-sideband phase noise, and harmonics typically better than -50 dBc below 20 GHz. Output power ranges from -20 dBm to +13 dBm (up to +15 dBm on select models), extendable to -110 dBm with Option 001 step attenuator. Multiple models address specific frequency bands: 10 MHz to 20 GHz (83620A/B/L), 45 MHz to 20 GHz (83621A/B), and 2 GHz to 20 GHz (83622A/B).
