Hi,
The SCXI-1000 is a rugged, low-noise chassis that can hold up to four SCXI modules. This chassis powers SCXI modules as well as handles all timing, trigger, and signal routing between your digitizer and SCXI modules.
SCXI chassis power SCXI modules, but are not intended to be used as external power supplies. Here are some links with more information about the SCXI:
