Model 875 | 10 MHz to 40 GHzMulti-Channel Vector Signal Generators

The Model 875 is an ultra-fast-switching vector-modulated signal source covering a continuous frequency range from 10 MHz to 40 GHz. The Model 875 offers switching speeds as fast as 200ns, enables ultrafast CW frequency sweeps, chirping, intra-pulse modulation and pulse shaping, all with very low phase noise. A high-performance internal I/Q modulator enables customized modulation waveforms and supports dedicated modulation schemes such as avionics modulations. This newly engineered design couples extremely deep memory and wideband capabilities - making complex modulation affordable and easy to program. 

Pulse Descriptor Word (PDW) is precompiled data format containing parametric information such as pulse duration (or pulse width), pulse amplitude, and frequency, including angle and time of arrival. These PDWs can be uploaded into the Model 875 internal memory through the Ethernet or USB communication ports. During playback, each PDW is translated into corresponding modulation parameters, sequentially and in real time. This generates a stream of modulated signals useful for radar simulation and other applications requiring more demanding modulation schemes. Additionally, multiple accurately timed PDW sequences, with phase coherence and calibrations, can be played back simultaneously with our multi-channel 875 VSGs.

Additionally, individual PDWs can be fed into the Model 875 internal memory sequentially and in real-time through the 875 Fast Control Port  (FCP) for immediate or delayed playback. This is a convenient way for research and development (R&D) engineers in verifying radar equipment on the fly. Users can quickly change parameters and have flexibility when designing complex radar simulations, especially in the demanding electronics warfare (EW) environment which often requires high pulse density.

Berkeley Nucleonics’ multi-channel Model 875 VSGs have a combination of fea­tures such as fast switching, phase coherence, phase-coherent switch­ing, and timing-accurate operation. With this new family of VSGs, users are able to eas­ily generate versatile and realistic pulse signals in radar, EW and 5G/6G Communications application scenarios. Mul­tiple lists of PDWs can be replayed from the internal memory or live-streamed through the fast control ports. The Model 875-4-40 offers four channels of accurately timed and phase calibrated signals in an "industry best" compact 2U package!
