- Testing over Ethernet with the SpaceWire GbE Brick 762.93 KBThis paper introduces a new SpaceWire test and development product with a Gigabit Ethernet interface developed by STAR-Dundee, the SpaceWire GbE Brick. It describes the unique features of the SpaceWire GbE Brick which make it ideal for both remote use in a test chamber and when connected directly to a PC using an Ethernet cable. The paper also characterises the performance of the SpaceWire GbE Brick and compares the performance to SpaceWire devices with PCI and USB interfaces.
- SpaceVPX-RTG4 Board with SpaceWire or SpaceFibre Backplane 1,015.31 KBSpaceVPX (VITA 78.0) is built on the ruggedized VPX standard. It addresses the need for redundancy in spaceflight systems and focusses on conduction cooled racks. SpaceVPX replaces the VMEbus control-plane of VPX with SpaceWire, while retaining the versatility of a user defined data plane serial interconnect. SpaceVPX-Lite (VITA 78.1) reduces the size and complexity of SpaceVPX. This paper describes a SpaceVPX-Lite board which uses SpaceWire and/or SpaceFibre for its backplane connections. The architecture of board is described along with its configuration options. An example application of the board as a wideband spectrometer is then described.
- SpaceWire Link Analyser Mk3 and SpaceWire Recorder 3.99 MBFor those responsible for testing SpaceWire equipment it is essential to be able to capture and view the traffic on a SpaceWire link in order to help validate the link is operating correctly and debug the link should any unexpected behavior be observed. The SpaceWire Link Analyser Mk3 and SpaceWire Recorder are two items of test equipment capable of transparently capturing large quantities of SpaceWire traffic on up to four links. New software written for these units displays the captured traffic in a variety of views that allow it to be examined in different levels of detail. This paper describes the hardware and software capabilities of the SpaceWire Link Analyser Mk3 and SpaceWire Recorder and provides descriptions and examples of some of the ways these can be used to perform SpaceWire link analysis.
