A separate, sound-isolated control room houses the data acquisition system and can double as a mechanical room for test articles with noise-emitting support equipment such as gas carts, chillers, compressors, and power supplies. Test operation, data acquisition, and customer control of the test article can be managed from the adjacent hallway.

The ATL provides 120 V AC and 208 V three-phase electrical power service as well as compressed air and chilled water to support the operation of test articles and test support equipment. Customized electrical connections and other specialized accommodations may be arranged.
