SpaceWire Recorder Mk2

The SpaceWire Recorder Mk2 is designed to support the validation and debugging of complete SpaceWire systems. It can be used to unobtrusively record and view large quantities of traffic travelling over up to four SpaceWire links. The visibility this provides greatly helps to confirm a SpaceWire system is operating correctly and aids debugging when problems are detected.

The Recorder Mk2 is inserted inline on SpaceWire links of interest. When recording is started, packets, time-codes and link errors are written to solid-state disk along with their time information. When recording is stopped, software indexes the recorded traffic to minimise access time, and then displays it in network and packet views ready to be inspected.

The SpaceWire Recorder Mk2 is a complete computer rack system. It consists of a cPCI chassis containing STAR-Dundee’s SpaceWire Recorder board, a powerful CPU card with two solid-state disks, and a power supply.

NOTE: The Recorder Mk2 supercedes the original SpaceWire Recorder. The Recorder Mk2 board now supports link speeds of up to 400 Mbit/s (previously 200 Mbit/s); a more compact and quiet chassis is provided; and the CPU board has been updated. Additionally, a much more capable software application has replaced the Traffic Viewer software, providing improved traffic visibility and enhanced functionality. Please note the new Recorder software application is compatible with the original SpaceWire Recorder and can be made available to download to existing Recorder users (please contact us for more information).
