Abstract : The Basic Circuit Modules program objective is to produce a design for a modular EMI measurement system. The program was divided into two parts. Phase I, which has been completed, was a study program to produce a design of the entire measurement system. Phase II has been directed toward producing a breadboard model of a portion of the system designed during Phase I. This report describes progress during the third quarter of the Phase II program. Test and evaluation of some of the modules used in the system were performed during this past quarter. The items evaluated included voltage controlled preselectors, portions of the IF module, digital to analog interface circuitry in the control system, a true RMS measurement system, and a phase-locked loop to stabilize the system LO source. Also defined were packaging formats for the control system and an amplitude distribution measurement system described in an earlier report. The remaining part of the program will be directed toward system testing and evaluation. (Author)
