Avionics
DT400 ARINC 429 DATABUS ANALYZER
The DT400 clearly establishes the standard for
databus equipment. Never have so many powerful
tools and features been assembled for supporting
your digital avionics.
Data may be read from up to four buses and displayed
in every format you might conceive
including graphic plots. Using the DT400's many
diagnostic functions adopted from the most
sophisticated logic analyzer systems, it is now
much easier to isolate troublesome intermittent
data. A suspect LRU can be monitored for hours
with a breakpoint condition programmed to
capture and display fault information. BITE mode
provides a very effective tool for interrogating
maintenance data from ARINC 604 avionics.
Equipment menus may be read, allowing the user
to select and view present fault data, and recall
flight data or generate a self test. You may even use
the DT400 to record fault messages for later viewing
or downloading. Here are some of the DT400's
powerful features:
