The HP/Agilent 83622A is a synthesized signal generator covering 2 to 20 GHz for RF and microwave component and system testing in aerospace, defense, and communications. Its phase-locked architecture delivers frequency resolution to 1 kHz (1 Hz with Option 008) and exceptional spectral purity—harmonics suppressed at least 50 dB below the carrier across the operating range, with phase noise of −76 dBc/Hz at 20 GHz and 10 kHz offset.
