    This would allow as many as 576 for a double-wide or 192 digital I/O for a single-wide VXI Module. In addition, the SMP7500 may be combined with any of the other members of the SMIP family to form a customized and highly integrated instrument/switch test solution. This allows the user to reduce system size and cost by combining the SMP7500 with another instrument/switch function in a single wide, C-size VXIbus module.
