4‑Slot, DC Chassis for SCXI—The SCXI‑1000DC 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‑1000DC chassis with a single multifunction I/O device or module for high‑channel‑count applications. You can power the SCXI‑1000DC with any 9.5 VDC to 16 VDC power supply.
