A Linear Time Base of Wide Range

Abstract
An oscillograph time base originally developed for work on the electrophysiology of nerves is described. Special features are the flexibility, linearity, and a range of sweep speeds from 0.6 msec. up to 60 sec., very slow speeds being obtained without the use of large condensers or resistors. A sweep voltage of 350 volts is available, which was applied directly to the x-plates of an oscillograph.
