The usefulness, efficiency and economy of cathode‐ray oscillography are improved by sweeping the spot across several successive lines on the face of the tube. There is presented a circuit which does this, with flexibility as to speed, delay, spacin

A circuit is described comprising an RC oscillator and multivibrator which generate three timing scales suited to calibrate a wide range of sweep speeds. In addition, a square pulse with adjustable duration is provided to calibrate the gain and to re
