About VXI Products

VXI Products developed and manufactured by the Advanced Research Products Group, is the newest addition to the Spectral Dynamics family. The AR products group (originally DSP Technology Inc.) established a name for itself in the mid 1970's. The AR Group has a long-standing tradition of designing dependable high performance CAMAC and later VXI data acquisition products and systems. The Spectral Dynamics credo of standing behind what we build is as true today as it was 30 years ago. The AR group products are no exception. Our newest VXI data acquisition hardware not only pushes the envelope on capabilities, it embodies the same rock solid design methodologies, which have always differentiated us from the competition. When combining this type of hardware and software expertise with the highest quality pre and post sales, field and in-house support you can be confident of mission success.
