Airman 1st Class Dillon Haas, 23d Operations Support Squadron radar, airfield and weather systems technician, uses a voltmeter to check the voltage of a receiver of a digital airport surveillance radar Aug. 27, 2020, at Moody Air Force Base, Georgia. The DASR identifies aircraft and transmits their location to radar approach control, which uses the radar to separate air traffic. RAWS technicians routinely inspect the DASR using test equipment to check signal levels, power supplies and functionality. (U.S. Air Force photo by Senior Airman Hayden Legg)
