The National Instruments PXI-1006AC is an 18-slot, 3U PXI chassis designed to support high-module-count modular instrumentation, data acquisition, and control applications. It accommodates both standard PXI and CompactPCI modules with a high-performance backplane featuring integrated timing, triggering, and local bus connectivity. The chassis delivers up to 600 W of usable power and combines efficient thermal management with flexible trigger distribution across three PXI segments, making it suitable for synchronized, demanding test and measurement environments.
Technical Specifications
• Slots: 18 PXI slots (slots 1 and 2 exclude local bus connections per PXI specifications; slot 1 designated as system controller slot)
• Compliance: PXI Specification, Revision 2.0
• System Clock: Independent 10 MHz reference clock (PXI_CLK10) to each peripheral slot; external clock input via PXI_CLK10_IN pin on star trigger slot P2 connector; supports synchronization of up to 17 modules
• Trigger Bus: Eight trigger lines on PXI trigger bus; star trigger bus with independent line per slot at less than 1 ns skew; three PXI segments with corresponding trigger bus divisions
