The Spanawave/Giga-tronics/Ascor 3000-62 is a 128-channel TTL I/O compatible driver VXI module delivering high-density digital interfacing for VXI-based test systems. Operating at 5V with bi-directional signal paths, this C-size module supports data rates up to 2 million read/write operations per second and scales from 128 to 512 channels across single and dual-slot configurations. The High Current option sources 32 mA and sinks 64 mA, enabling external coaxial switch control and demanding load switching applications.
