The Keysight (Agilent HP) 83711B is a synthesized CW signal generator spanning a frequency range of 1 GHz to 20 GHz. Designed to balance performance and value, it utilizes fundamental oscillators and switched low-pass filters to achieve high spectral purity with eliminated subharmonics and low harmonic levels. It delivers high output power (typically greater than +14 dBm) and serves as an ideal local oscillator (LO) driver or signal source for non-modulated test applications. An optional step attenuator (Option 1E1) is available to extend its power range down to -110 dBm for receiver sensitivity testing.
