The Model CRA is a complete Oscillograph with built-in linear sweep circuit, input amplifiers, and complete power supply for operating the standard 3-inch cathode-ray tube.
The model CRB Cathode-Ray Oscilloscope is identical with the above instrument, with the exception that the linear sweep circuit is not included. This circuit is not required for securing receiver selectivity curves when the model OM Modulated Oscillator is used, as well as in many other applications.
