Fast Single-Channel Pulse-Height Analyzer

Abstract

A circuit description and performance evaluation are presented for an analyzer capable of processing pulses with risetimes as fast as 7 nsec and widths as narrow as 10 nsec. An integral nonlinearity of ±0.15% and a differential nonlinearity of ±3.5% were obtained over its dynamic range of 100:1. The maximum input repetition rate for the lower and upper level thresholds was 13 and 5 Mc, respectively, when using a 12 nsec input pulse width. The entire analyzer is mounted on a single‐sided 11.4×17.8 cm printed circuit board.
