Berkeley Nucleonics Model 845 is a low-noise and fast-switching microwave signal generator covering a frequency range from 10 MHz up to 20 GHz+. The Model 845 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 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.
