Ground-air-ground communications are used world wide to control aircraft traffic and require the interconnections of multiple transmitters, receivers, recorders, microphones, antennae, etc. In such complex systems it is highly desirable to have some means of measuring the overall system performance with one simple test so that performance degradation can be constantly monitored. After some experimentation, it was decided that a measurement of the system distortion to a 500 Hz tone was a suitable parameter. It is also important to measure the system overall gain so that the operators can be alerted to any drastic change in levels throughout the system. The equipment described in this report was designed specifically to perform both of these measurements. Author
