The National Instruments PXI-1052 is a 12-slot modular chassis that combines a 4-slot PXI subsystem with an 8-slot SCXI subsystem for integrated signal conditioning, multiplexing, and switching in automated test environments. Compliant with PXI Hardware Specification Revision 2.1, this platform delivers advanced timing and synchronization capabilities while maintaining a low-noise architecture for precision instrumentation. The integrated SCXI high-voltage analog backplane and low-voltage analog bus enable direct control from PXI DAQ/DMM modules without external cabling.
