12‑Slot, AC Chassis for SCXI—The SCXI‑1001 is a rugged, low‑noise chassis that powers SCXI modules as well as handles all timing, trigger, and signal routing between other modules and SCXI modules. For larger systems, or future expansion, you can also daisy chain up to eight SCXI‑1001 chassis with a single multifunction I/O device or module for high‑channel‑count applications.
