The Keysight (formerly Agilent / HP) 8665A is a high-performance synthesized RF signal generator suitable for basic and advanced receiver testing. Operating up to 4.2 GHz, it offers excellent spectral purity with low-noise enhancements available for out-of-channel receiver testing or low phase jitter clock applications. The instrument supports AM, wideband FM, and optional pulse modulation for radar testing.
