S1435 Series Signal Generator

S1435 series signal generator achieves balance in terms of performance, economy and volumetric weight. It responds fast and switches to another frequency in only 1ms, which shortens the test time and improves test efficiency, meeting the needs of massive data testing. In addition, it also has excellent analog modulation and pulse modulation functions. By adopting advanced frequency synthesis and RF channel signal processing technologies, it can achieve high performance while reducing the cost.

Besides, S1435 series signal generator is equipped with a 7-inch high-sensitivity LED touch screen, and supports operation by touch screen, panel buttons, rotary knobs, external mouse and keyboard, etc., which fully upgrades the users’ operation experience. It adopts portable 3U chassis structure and is featured by small size and light weight, and thus is easy to carry. The S1435 series signal generator can meet both the test requirements for high performance in the R&D phase and the test requirements for high efficiency in the production phase.
