Boxcar controller for low-repetition-rate use

Abstract
We present a simple digital circuit which will control a Princeton Applied Research Corporation (model No. 164) boxcar integrator and thereby allow full utilization of the linear sum mode. This provides for improved signal‐to‐noise ratios and shorter data acquisition times for short signals [10–50 ns occuring at moderate repetition rates (1–20 Hz)]. This provides significant data acquisition time savings for low‐repetition‐rate, high‐time‐resolution measurements. It also increases the signal‐to‐noise ratio in many circumstances.
