Abstract : Azimuth pulse generators and a digital-to-synchro converter were subjected to tests at the National Aviation Facilities Experimental Center to ascertain their compliance with engineering requirements and to determine their performance in supplying antenna azimuth position data to a Radar Video Data Processor (RVDP). The azimuth pulse generators were installed in the antenna pedestal of the experimental airport surveillance radar (ASR-5) facility, and the digital-to-synchro converter was installed at the radar display subsystem. Utilizing digital computer programs, RVDP output messages were tabulated and analyzed to determine precision in reporting antenna azimuth. Test results indicated that the azimuth pulse generators and the digital-to-synchro converter performed satisfactorily, and acceptably provided antenna azimuth position data to the RVDP. Difficulties encountered during the tests were related to the type of coupling between the antenna and the azimuth pulse generators, which resulted in a recommendation to use only a worm-gear method of coupling.
