Abstract : The article describes a small pulse analyzer, using a new ferrite data recorder, the block diagram of which is shown. Its main parts are the input unit, the data recorder, the control block, and the data readout blocks. The input unit converts the pulse height into a sequential digital code and does not differ essentially from the standard circuits used for the purpose. The new type of data recorder has three main features which increase its operating reliability and reduce the volume of the electronic equipment: (1) A single reading winding is used in the sequential access to the number digits, a single amplifier with discriminator, and an arithmetic unit consisting of a single flipflop only. This increases greatly the operating stability. (2) The possibility of using a half-adder consisting of a single flipflop likewise reduces the data-recorder failure probability. (3) The reliability is also increased through the use of a small number of elements for setting the reading and writing currents and through the absence of an inhibiting current. The data recorder provides for the storage of 128 16-digit numbers, and its construction and operations are briefly described. All the other units are described in some detail. A breadboard of the analyzer was tested and the suitability of the equipment for its purpose is demonstrated. The breadboard measured 362 x 350 x 450 mm and weighed approximately 20 kg. The readout time for a single number is approximately 2 sec and for all the numbers is approximately 4 min. If only half of the channels are filled, the circuitry can be modified so as to reduce the readout time to one-half.
