Abstract
A counter chronometer is described which measures time intervals up to 12.75 microseconds by counting the oscillations of a 20 Mc/s free-running oscillator with a scaler. Provision is made for resetting the scaler by a fast pulse if the measurement is not to be recorded. The scaler is based on conventional pentodes and germanium diodes, the high counting speed being attained by limiting voltage changes.
