The Tektronix VX4469A is a C-size VXI module that simulates ARINC 629 communication bus traffic and injects errors for testing Line Replaceable Units (LRUs) in avionics systems. This third-generation platform delivers bit-level, word-level, and message-level error injection capabilities, enabling thorough validation of ARINC 629 interface behavior. The module supports up to three terminals with full error injection simultaneously or operates in multi-terminal emulation mode for real-time bus analysis. Aircraft such as the Boeing 777 employ ARINC 629, making this module essential for avionics qualification and troubleshooting workflows.

– Compatibility & Integration
The VX4469A installs directly into Tektronix/CDS VXIbus Mainframes with thermal management assured. When placed in a slot with empty adjacent slots, VME daisy-chain jumpers must be installed on the mainframe backplane per manufacturer instructions. Complete operational, installation, and troubleshooting guidance is provided in the user manual supporting firmware 1.00 and later.
