VME

In 1992, Highland Technology entered the VME market with the V460 source/measurement meter and V550 LVDT/RVDT scanner. Since then, Highland has maintained a consistent commitment to VME as an open, robust, and cost-effective platform for high channel count control, measurement, and simulation systems.

Highland Technology is a member of VITA, the VME standards body, and continues to release new technology into the VME market. As other bus architectures come and go, Highland remains confident that VME will maintain its position as the architecture of choice for essential, long life cycle programs.
