Generator of Linearly Varying Voltage
John Z. Levinson · Review of Scientific Instruments · 1956
An all-electronic generator is described which provides a voltage which varies linearly with time between adjustable positive and negative limits. Such a generator lends itself well to the automatic recording of current-dependent phenomena. Linear variation is obtained on both the rising and falling half-cycles, so that complete reversal of slow processes may be assured. The maximum current provided in either direction is 3 amps. The limit is determined by the number of output tubes connected in parallel. Cycling periods up to 1 min in length are provided.
