The MIl-STD 1553 serial bus is primarily used to interconnect avionics equipment in military aircraft. This bus is based on tri-level signaling (high, low, & idle) and requires dual-threshold triggering, which the 4000 X-Series supports. This bus is also implemented as a redundant multi-lane bus (dual-bus analysis), which is also supported by the 4000 X-Series.
The ARINC 429 serial bus is used to interconnect avionics equipment in civilian aircraft (Boeing & Airbus). This bus is also based on tri-level signaling (high, low, & null) and requires dual-threshold triggering, which the 4000 X-Series supports. Since ARINC 429 is a point-to-point bus, multi-lane analysis is also required to capture both send and receive data.
The DSO4XAERO option provides decoding and triggering on both of these buses. This option supports the same serial bus features available on other 4000 X-Series supported serial standards including Lister display format, Search & Navigation, and dual-bus analysis.
