• Model 835-4
LabVIEW Certified

Berkeley Nucleonics' Model 835-4 is a low-noise, fast-switching analog signal generator that covers a frequency range from 9 kHz up to 4 GHz.

The Model 835-4 is a low phase noise, fast-switching RF signal generator with µHz frequency resolution and precisely leveled power range from -120 to typically +18 dBm. It combines excellent signal quality, high-quality analog modulation, and fast switching capabilities. Flexible and simultaneous modulation allows complex signal simulation. The internal OCXO guarantees a high stability time base and can be locked to an external reference in the range of 8 to 200 MHz. The modular design simplifies maintenance and minimizes cost of ownership.
