The Model DB-2 is a pulse generator which accurately simulates the random and pileup characteristics of pulses from a radiation detector. It provides pulses which are monoenergetic over a broad range of average count rates. Under high count rate conditions, the pulses will pileup. This characteristic is useful in determining pile-up or count-rate effects and in measuring the resolution of high count rate spectroscopy systems.
Besides random pulses, the Model DB-2 also provides monoenergetic repetitive pulses. In this mode, the DB-2 is an excellent general purpose pulser. When the EXT REF input is used, the DB-2 provides sliding pulses to quickly check system or component linearity. Since the DB-2 is a random pulser, a general purpose pulser, and has sliding pulse capabilities, it is one of our most versatile models.
