Boxcar controller for low-repetition-rate use.
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.
