Avionics DT400
Sets a standard for databus test device in the field or shop
The DT400 clearly establishes the standard fordatabus equipment. Never have so many powerfultools and features been assembled for supportingyour digital avionics. Data may be read from up to four buses and dis-played in every format you might conceive including graphic plots. Using the DT400's manydiagnostic functions adopted from the mostsophisticated logic analyser systems, it is now
much easier to isolate troublesome intermittentdata. A suspect LRU can be monitored for hourswith a breakpoint condition programmed to capture and display fault information. BITE modeprovides a very effective tool for interrogatingmaintenance data from ARINC 604 avionics.
Equipment menus may be read, allowing the user
to select and view present fault data, and recallflight data or generate a self test. You may even usethe DT400 to record fault messages for later view-
ing or downloading. Here are some of the DT400'spowerful features:
