With this previous discussion as background, it can be stated that this paper will describe a test set designed and slated to be produced on a "limited edition" basis at C-COR for the express purpose of making the "nuts and bolts" measurement of signal level, noise, and distortion throughout a CATV system. The major economic motivation in our case is the potential improvement in efficiency in our own Systems Engineering Department.
In addition, certain specialized production test units constructed and used by C-COR will be briefly discussed. Some of these represent the forerunner of the circuitry used in the test set; others are shown because they illustrate the similarity between field test and production test or may have some value around a maintenance laboratory.
A review of some of these factory test units, designed and built at C-COR will follow in the succeeding paragraphs.
