Abstract
A SIMPLIFIED portable oscillograph having a number of new optical and electrical features is described in this paper. The optical system, which consists of a combination of cylindrical lenses with axes at right angles, is designed to permit simultaneous viewing and photographing. A continuous time axis for both the viewing screen and film is secured by means of a small, variable speed, revolving mirror.
