Military Protocol Trigger and Decode for Infiniium Oscilloscopes
The D9010MILP software package for Infiniium oscilloscopes gives you the ability to trigger and decode SpaceWire, ARINC429, and MIL-STD-1553 signals. This package applies to all Infiniium Oscilloscopes.
The ARINC 429 bus and the MIL-STD-1553 bus are serial buses used in both commercial and military equipment. While primarily used in avionics, these buses are also found in ground vehicles, weapons systems and other equipment. Because of their importance in both industry and defense, error free operation of both the ARINC 429 bus and the MIL-STD-1553 bus is crucial.
SpaceWire is a spacecraft communication network based in part on the IEEE 1355 standard of communications. It is coordinated by the European Space Agency (ESA) in collaboration with international space agencies including NASA, JAXA and RKA. SpaceWire supports highly fault-tolerant networks and systems, which is one reason for its popularity. SpaceWire is a standard for high-speed links and networks for use onboard spacecraft, easing the interconnection of sensors, mass-memories, processing units, and downlink telemetry sub-systems.
Without intelligent oscilloscope serial bus protocol triggering and decode, it can be difficult to debug these buses and validate signal integrity. Traditional methods of debugging serial buses include manual bit counting, which is not only tedious, but prone to critical errors. Easily debug and test these serial buses through D9010MILP Protocol Triggering and Decode for Infiniium Oscilloscopes. This application provides an easy-to-use interface, a breadth of protocol decode options to suit your specific needs, pattern and error search options to find errors faster, and much more.
ARINC (Aeronautical Radio INC.) 429 is a data transfer standard for aircraft avionics. It uses a self clocking, self-synchronizing data bus protocol (Tx and Rx are on separate ports). The physical connection wires are twisted pairs carrying balanced differential signaling. The protocol allows for self-clocking at the receiver end, thus eliminating the need to transmit clocking data. ARINC 429 is an alternative to MILSTD-1553.
MIL-STD-1553 was originally designed as an avionic data bus for use with military avionics, but has also become commonly used in spacecraft subsystems, both military and civil. It features multiple redundant balanced line physical layers, a differential network interface, time division multiplexing, half-duplex command/response protocol, and can handle up to 30 Remote Terminals (devices). A single bus consists of a wire pair with 70–85 Ω impedance at 1 MHz.
SpaceWire utilizes asynchronous communication and allows speeds between 2 Mbit/s and 400 Mbit/s, with an initial signaling rate of 10Mbit/s. SpaceWire also has very low error rates, deterministic system behavior, and relatively simple digital electronics. SpaceWire is bi-directional, using two twisted pairs in each direction.
