Design Features of a Start-Stop Time-to-Amplitude Converter

A time-to-amplitude converter of the start-stop type is described. Automatic suppression of readout in the absence of a timely stop signal and an analog memory, which permits delay of readout to allow independent evaluation of a conversion, are two of its several novel design features. With full scale ranges of 0.1 usec to 30 usec, the instrument provides good linearity, stability and resolution over a wide range of operational conditions.
