Circular Sweep Chronograph for Single Millisecond Time Intervals
A. Linz · Review of Scientific Instruments · 1952
A chronograph is described which measures single time intervals up to 1000 microseconds with an accuracy of ±10 millimicroseconds. The instrument consists of a 100-kc counter chronograph with a 10-microsecond circular sweep to interpolate between scaler readings. Suitable pulse sharpening circuits and a five tube, high speed gate circuit in which the pulses defining the timing interval form the edges of the gate are also described. The possibility of extending the precision of the time measurement to ±1 millimicrosecond is indicated.
