With various switch modules, it can scan at rates up to 350 channels per second, or open/close 200 channels in less than 0.1 second. The 3499A is compact, requiring only 2U height in a full rack.

The 3499A has a concise user interface that is designed for manual operation on the manufacturing floor or in desktop applications.
