Model 845

Model 845 | 100 kHz to 26.5 GHzMicrowave and RF Signal Generator

Berkeley Nucleonics' Model 845 RF Microwave Signal Generator is a low-noise and fast-switching microwave signal generator covering from VLF to K-band, 100 kHz up to 26.5 GHz (with the option to extend the frequency down to 9 kHz). The Model 845 Microwave RF Signal Generator offers a wide and accurately-leveled output power range with high spurious suppression. Advanced frequency synthesis with fractional-N divider makes for low SSB phase noise and sub-Hertz frequency resolution.

The Model 845 is available in 12, 20, & 26.5 GHz frequencies with a touch screen display. In addition, Model 845 can be customized and configured to each user's specific needs. There are many options to determine your best configuration.  Please see the options list below or contact BNC for support.

Rich Set of Features in the Model 845 Series

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 an internal pulse train generator as standard. Three internal modulation sources are available, and all modulation modes 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. 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 provide the types of signals occurring in pulse radar applications with a rotating antenna. What's more, the combination of FM and AM can be used to check the fading effects of FM receivers.

The Model 845 operates online or battery power making it useful for field applications or large laboratories. The Model 845 Signal Generator introduces the smallest footprint in its class

Frequently Asked Questions (FAQ) 

Model 845 | Why is the front panel so small ? 

Model 845 | Why is the front panel so small ? 

The Model 845 is a small footprint benchtop Microwave Signal Generator with very high performance. The space saving packaging eliminates most of the front panel controls in favor of a software GUI that can be developed and enhanced over time. The low power requirements are equally resourceful, even allowing for a battery option.
