Programmable real time bus emulation with real time data update

To meet the bus emulation requirements for digital avionics many Automatic Test Equipment (ATE) and/or Test Program Set (TPS) suppliers must design peculiar hardware in test stations or Interface Test Adapters (ITAs) to meet real time bus emulator requirements. Recently, BAE SYSTEMS Mission Solutions completed a rehost of the Central Electronics Unit (CEU) Line Replaceable Unit (LRU) TPS for the LANTIRN (Low Altitude Navigation and Targeting Infra-red for Night) Targeting Pod. This paper details how BAE SYSTEMS was able to implement this complex TPS requirement with their General Purpose Bus Emulator Card, eliminating the need for peculiar interface hardware contained in the Legacy ITA.
