SpaceWire Link Analyser Mk3

The Link Analyser Mk3 is designed to unobtrusively monitor the traffic on a SpaceWire link. It can capture and display bi-directional traffic travelling over a link; it can display live link statistics; and it can output decoded SpaceWire link characters and events to an external logic analyser.

The SpaceWire traffic visibility this provides is essential when developing and testing SpaceWire equipment. It makes it possible to validate a SpaceWire link is operating correctly and greatly aids debugging when problems are detected.

The Link Analyser Mk3 is typically connected between two SpaceWire devices, where it transparently monitors link traffic. When a pre-defined capture trigger is detected, SpaceWire characters and errors, along with a trace of data and strobe signals, are captured to hardware memory. Once capture is complete, the SpaceWire traffic is uploaded to a host PC where it is interpreted and shown in multiple views. Each view displays traffic in different levels of detail, allowing it to be inspected at network, packet, link and signal levels.

The Link Analyser Mk3 is controlled by a host PC, connected by a high-speed USB 3.0 interface, and is powered by a 5V power brick. It has two SpaceWire ports, four external SMB triggers and two MICTOR logic analyser connectors.

NOTE: The Link Analyser Mk3 supersedes the original Link Analyser and the Mk2. Both the hardware and software have been significantly improved. These improvements are described in SpaceWire Link Analyser Mk3 vs Mk2.
