“The benefit from using SpaceWire is a lower cost for development, a reduction of development time, better reliability, and an increase in the amount of scientific work that can be achieved within a limited budget.” NASA

4Links test equipment, in turn, reduces SpaceWire development cost and time, and increases what can be achieved within a limited budget. It is unmatched in its bug detection, its diagnostics, its instrumentation of time, and its remote-test capability over the Internet.  Like SpaceWire itself, 4Links test equipment scales, from testing a single device up to coordinated testing of tens or hundreds of SpaceWire nodes. Easy upgrades minimise equipment costs over the life of a project. All of these help to solve problems quickly, before they incur cost and delay. Customers using 4Links test equipment have quickly detected — and solved — problems that had long remained undetected or unsolved.

 For customers needing a second opinion on their own designs, or an evaluation of a SpaceWire product that they intend to use, 4Links offer a SpaceWire Validation Service that builds on the unique capabilities of our test equipment and our unique experience of developing with SpaceWire.

For customers wanting easy and robust implementation of SpaceWire, we are preparing a range of SpaceWire IP products, from simple interfaces to complex systems-on-chip, all based on the simple and robust SpaceWire design that has been proven by so many users of our test equipment.

4Links and CEO Paul Walker were in at the birth of SpaceWire and the company possesses a depth of knowledge unrivalled in the industry.
