Abstract:

The object of the invention is a device for measuring current gain of transistors value for the coefficient of amplification in current of semiconductor triodes connected in accordance with a system with a grounded emitter which contains a power supply connected up through a resistance to the base and the collector of the transistor being tested and a measurer joined with it of the value for the current of the base with a given value for the collector current. For the purpose of simplifying the automation of the process of measurements as a power supply of the base circuit, there is used a generator of linearly changing voltage, and as a measurer of the current of the base there are connected into the base and collector circuits of the transistor, comparing currents joined with an electronic commutator connected between the output of a frequency-stabilized generator of AC and the input of the counter of the periods of oscillation.
