The report is concerned with the establishment of a signal density monitoring facility. The facility, which is designed to measure ambient noise and signal densities over the frequency range from 100 Mc to 30 Gc, is described from a block diagram point of view. Two other studies of various parameters and equipment which affect the operation of the facility are included. The first concerns a study of the effect of AGC circuitry on the output of a RF noisemeter when the input signal is not a continuous function of time. The study has both theoretical and experimental aspects. An equivalent circuit for the noisemeter is derived and programmed on an analog computer. The second study is concerned with various noisemeter output circuits and the effect of receiver bandwidth. Author
