Berkeley Nucleonics' Model 845 RF Microwave Signal Generator is a low-noise and fast-switching microwave signal generator covering a frequency range from 10 MHz up to 20 GHz+. The Model 845 Microwave RF Signal Generator offers a wide and accurately-levelled output power range with high spurious suppression. Advanced frequency synthesis with fractional-N divider makes for low SSB phase noise and micro-Hz frequency resolution. The Model 845 Microwave RF Signal Generator also includes AM, DC-coupled, low distortion wideband-FM, PM, FSK and PSK, frequency chirp, and fast pulse modulation with internal pulse train generator as standard. Three internal modulations sources are available. All modulation modes of the Model 845 can be combined. This allows the generation of complex modulation signals for modern communication and location systems. The Model 845 is ideally suited for applications where a high-quality CW microwave source with analog modulation is required. It includes AM; DC-coupled wideband-FM, PM, FSK and PSK, and fast pulse modulation as standard. Optionally, frequency chirps and programmable pulse trains can be provided. The Model 845 operates with an ultra-stable temperature compensated 100 MHz reference (OCXO) and can be phase-locked to any external reference from 1 to 250 MHz. Additionally, The combination of pulse modulation and FM simulates Doppler effects or chirp signals. Simultaneous AM and pulse modulation provides the types of signal occurring in pulse radar applications with rotating antenna. The combination of FM and AM can be used to check fading effects of FM receivers.
