| Abstract: | For the fast prototyping, production, and delivery of commercial radio frequency products/systems, accurate and reliable test systems are necessary. These systems are usually product customized and thus expensive solutions, capable of performing all necessary measurements for a specific product. The purpose of this paper is to present a flexible cost‐effective test solution, capable of realizing all necessary measurement on a high output power amplifier system greater than 500 W, and to generate essential reports. These reports allow the system operator to (i) perform an analysis and a statistical comparison among various products, assuring that the quality is the same for all products; and (ii) retain products that present a performance poorer than other similar products, without a rigorous technical analysis, thus increasing efficiency in factory assembly line.
