Astronics / EADS / Talon Instruments BE-64 Bus Emulator/Word Generator

The Astronics/EADS/Talon Instruments BE-64 is a C-size VXI card that functions as a dual-mode bus emulator and word generator for digital test and troubleshooting applications. The instrument simulates microprocessor-like bus structures and digital interfaces with proven architecture capable of emulating over 1,000 different interface configurations. It supports pre-configured setups for VME, VXI, Multibus, AT, NuBus, SCSI, Microchannel, EISA, and S bus structures.
