Test Facilities

The electromagnetic compatibility test facility is used for checking the functional deterioration of electronic equipment on board launch vehicles and spacecraft due to electromagnetic interference between the equipment themselves. This facility offers interference emission testing to measure the electromagnetic noise emitted from a test item, and susceptibility testing to verify the normal functions of a test item by providing it with electromagnetic noise.
Tests are performed in a shielded room which isolates a test item from external electromagnetic noise. In interference emission testing, the electromagnetic noise emitted from a test item into the open space is measured with an antenna while that conducted along cables is measured with a current probe. In susceptibility testing, meanwhile, electromagnetic noise which has been either feedback-controlled using an electric-field sensor or generated by a signal generator connected to the cables of a test item is applied to a test item.
Possessing a test system which can handle up to 40 GHz, this facility makes it possible to perform tests with the levels required by the Military Standards and the International Space Station (ISS.)
