The TCI Model ATS-400 is designed to test, display and simulate the output of Altitude Reporting Equipment, which conform to the ICAO Standard for SSR Pressure Altitude Transmission. In accordance with the U.S. National Standards for I.F.F. Mark X (SIF)/Air Traffic Control Radar Beacon System SIF/ATRBS.The ATS-400 utilizes an advanced RISC microprocessor to display the output of these devices in both numeric and binary forms, with an input altitude data range covering the full ICAO code from --1000 to +126,000 feet. The ATS-400 will also display the output of altitude reporting devices that transmit data in a serial format. Serial altitude data i
