A 600 Mc/s Pulse telemetry system

This paper is mainly concerned with the ground equipment for a telemetry system employing pulse-position modulation in which the information is conveyed by vaiations of the delay time between a wide datum pulse and up to twenty narrow pulses. In order to explain the nature of the signals with which the ground equipment has to deal, a brief description is given of the airborne equipment. This is followed by a description of the operational ground equipment and of the ancillary equipment for calibration and illustrate some of the problems involved ment and methods used to meet certain testing. Finally, details are given which in the development of the ground equipment design requirements.
