New circuits for recurrent surge oscillography

This new transient analyzer, a combined recurrent surge generator and oscillograph, has many new circuits to increase the convenience and accuracy of transient response measurement. A 400-cycle surge generator gives intense images. A vertical-bias system on the cathode-ray tube provides unmetered bias for positioning, metered bias for displacement-type deflection measuring, and astigmatism control for measuring small differences of large voltages. A time-measuring circuit provides two blank spots on the sweep whose positions are adjustable and metered.
