Key Features & Specifications

  • Nine module slots (1, 2, and 3 slot wide spaces)

When you need a larger amount of switching in your test system or combined electronic and optical switching, the 9/14-slot 3499C mainframe will meet your needs. Requiring only 5U height in a full rack width configuration, it can route up to 360 channels of DC multiplexing or accommodate 4 to 6 of the 2-slot or 3-slot optical modules. With various switch modules, it can scan at rates up to 350 channels per second, or open/close 360 channels in less than 0.1 second.

The 3499C has a concise user interface that is designed for manual operation on the manufacturing floor or in desktop applications. High-performance switching modules, multi-function modules, built-in relay cycle counters and easy interconnections all work together to provide a switching solution you can trust.

See the new 34980A Multifunction Switch/Measure Unit as a new low-cost alternative.
