Ludlum Measurements, Inc. Page 1-1 January 2016
Introduction
he Model 2929 is a dual-channel scaler designed for use with
“Phoswich” and/or proportional detectors. A pulse height
analyzer is employed to provide information to the two
independent counters.
The Model 2929 is powered by a 95 to 250 Vac wall transformer with an
output of 24 Vdc. It has a built-in detector high voltage power supply
with front panel readout, as well as adjustable count time periods
ranging from 0.1 to 990 minutes. It also has a click-per-event audio for
each of the two channels. The unit will operate two printing calculators
(Ludlum Model 264) by way of data connectors located on the rear
chassis. The amplifier circuitry consists of a three-stage amplifier fed
directly to the discriminator circuit. All discriminator controls are
located internally and are easily accessible internally on the right-hand
side of the chassis.
The Model 2929 is generally used in conjunction with a Model 43-10-1
Alpha/Beta Sample Counter.
