DABS (Discrete Address Beacon System) Interrogation Modulator.

Abstract

This report describes the development of a user friendly discrete address beacon system (DABS) interrogation modulator unit. The unit was designed to support an automatic testing program to define the degree of compatibility of the DABS (now Mode S) system with the Mark XII Mode 4 IFF system. The design philosophy, implementation, and software development of this microcomputer-controlled phase and amplitude waveform modulator is reviewed both for users of this equipment and as a guide for those developing similar specialized equipment. This interrogation modulator has proven to be flexible in use in connection with DABS as well as on other IFF programs. Appendix A includes helpful development and debugging aids and some lessons learned. Keywords: Discrete Address Beacon System (DABS/Mode S), IFF system; Test equipment, Microprocessor controlled test equipment.
