Backplane Testing

The MPT-DMUX distibuted backplane tester uses computer controlled, state-of-the-art modular switching architecture to evaluate and test backplanes for telecommunications, military and avionics applications.

With distributed switching mounted on custom designed paddle cards, the MPT Backplane Tester can test units exceeding 30,000 test points.

Each distributed switching card contains from 256 points of solid state switching. Any number of switching cards can "snap" into a custom designed paddle card. This switching system allows low voltage testing of backplanes where interfacing with traditional radial interface cables is either impossible or very cumbersome. The real strength of the system is very high density connections with low power testing.

The MPT-DMUX solution offers reliable, fast set up times, reduces test cycle time and eliminates the constant trouble shooting required with competitive 'wired' systems.

​Key Features Include:

  • Paddle card and loading station design to reduce load/unload time.

  • Algorithms to quickly identify open/short within high density of test points (>30,000).

  • Extremely fast test speeds of up to 3000 continuity scans per second.

  • Mixed high and low voltage energization for selective HiPot and low voltage testing of power and ground circuits in backplanes.

  • Custom designed paddle cards adapt the MPT to the backplane under test.
