Rugged Dynamic Signal Test and Analysis System - RE-884U

The RE-884U Rugged Dynamic Signal Test and Analysis System, with compact structure, dustproof and anti-vibration, and maximum sampling frequency of 200kHz, is especially designed for data acquisition in various harsh environments, such as on-vehicle, airborne, and shipboard, etc. Expanded via a Gigabit Ethernet switch, the dynamic signals over 1000 channels can be measured and analyzed in parallel and synchronously by a single computer. RE-884U is widely used for the performance test and analysis of various structures in the field of national defense and military industry, aerospace, automobile industry.
