Astronics / C&H Technologies VX403C VXI Industry Pack Carrier Module

The Astronics / C&H Technologies VX403C is a VXI Industry Pack Carrier Module that integrates up to four single-height IP modules - or two double-height modules - into a single VXI slot. Each installed IP module appears as an independent VXI instrument with its own logical address, mechanical interface, and control path. The carrier provides 50-pin header interfaces accessible from the front panel, enabling direct electrical and data connectivity to Units Under Test through a library of over 200 available IP modules. ## Technical Specifications • VXIbus Compliance: ANSI/IEEE Std 1014-1987, VXIbus Revision 1.4; operates as 16/24/32:D16 DTB Slave • Form Factor: Size C carrier; dimensions 233.35 mm (9.187 in) high × 160 mm (6.299 in) deep for 20.32 mm (0.8 in) slot spacing • IP Module Capacity: Up to four single-height or two double-height Industry Pack modules per carrier • IP Interface: Standard 50-pin IDC socket headers on each module slot • Power Supply Requirements: +5V (1.2 A typical) and +12V from VXI backplane; isolated and filtered supplies provided to IP modules • Trigger Interface: VXI TTL trigger lines (up to eight) configurable via jumpers to any combination of resident IP strobe inputs • Interrupt Handling: Each IP module supports two independently programmable interrupts; individual interrupt vectors and release capability (RORA/ROAK) per module ## Key Features • Individual logical addressing for each installed IP module enables independent control and monitoring • Flexible trigger routing allows single-line synchronization across all IPs or independent clocking of individual modules • Modular design supports custom UUT interfaces through selection and combination of industry-standard IP modules • Isolated power distribution protects IP modules from backplane noise ## Typical Applications Multi-channel test systems requiring diverse signal interfaces; automated test equipment leveraging IP module specialization; VXI-based measurement and stimulus configurations. ## Compatibility & Integration Fully compliant with VXIbus Specification Revision 1.4 for register-based modules and VMEbus Specification ANSI/IEEE STD 1014-1987, IEC 821.
