NI SCXI-1001 SCXI Chassis

The National Instruments SCXI-1001 is a 12-slot chassis that houses, powers, and controls SCXI signal conditioning modules for high-channel-count data acquisition systems. The SCXIbus backplane provides internal signal routing for analog and digital signals, managing timing, triggering, and signal distribution between modules and DAQ devices. Its low-noise, shielded enclosure minimizes electromagnetic interference for accurate acquisition of weak signals.
