Avionics and Space Instruments

Our specialises in the design and manufacture of Flight Test Instrumentation, Aerospace Telemetry Products, Systems and Solutions including Video and Data Link products.

We have developed a unique range of USB Powered, small sized but high performance Signal Recovery products which communicate with a host computer over a USB Bus port. The Symmetric USB product range includes Receivers, Bit Synchronisers, Decommutators and Simulators which are available as single function modules or as combined function modules.
