Combining Digital and RF Technology to Design a Telemetry signal Simulator

Abstract

With the rapid increase in technology, telemetry systems today employ a variety of modulation formats, modulation rates and frequency ranges. These telemetry systems will require sophisticated test equipment capable of simulating several types of telemetry data. This paper will discuss how digital and RF technology can be merged to develop a new telemetry signal simulator capable of testing today's sophisticated telemetry systems. The paper will further discuss how digital techniques merged with RF techniques can provide testing capabilities previously unavailable in telemetry signal generators such as diversity fade simulation and Doppler shift simulation with programmable range and rate.
