An Automated Safeto- Mate (ASTM) Tester

Safe-to-mate testing is a common hardware safety practice where impedance measurements are made on unpowered hardware to verify isolation, continuity, or impedance between pins of an interface connector. Performing this on critical flight hardware under test and its associated GSE ensures minimal risk when the hardware is powered. Historically, safe-to-mate measurements are performed manually with data written into paper procedures. This laborious process potentially requires a large amount of time for connectors that could have as many as 104 pins. Risks include human error in performing the measurements on sensitive inputs or in recording the data as well as potential loss of hardcopy data.
