Aeroflex IFR DT200 Databus Analyzer

The Aeroflex IFR DT200 Databus Analyzer is a portable, battery-operated diagnostic instrument for capturing, analyzing, and simulating ARINC 429 and Commercial Standard Digital Bus (CSDB) avionics databus traffic. Field and laboratory technicians use the DT200 to validate systems, detect faults, and support integration tasks across dual-mode operation. The instrument displays data in hexadecimal, binary, or engineering units, with onboard functions including freeze, scroll, clear, and graphic time-plot rendering.

Recording capacity spans approximately 20 minutes for dual-label configurations at 1 word per second, with playback supporting graphics plots, hex lists, or DC output. Battery runtime extends to 6 hours on internal rechargeable cells, enabling extended field deployment.
