PROCEDURE TESTING ELECTRIC PARAMETERS OF AMPLIFIER, AUTOMATED SYSTEM TESTING ELECTRIC PARAMETERS OF AMPLIFIER Russian patent published in 2003 - IPC

FIELD: measurement technology, approval and presentation tests. SUBSTANCE: given procedure consists first of all in setting of tested electric value of amplifier, in formation of train of controlling signals and starting data for its test which are then amplified and converted from digital to analog form, in formation of voltage of key action and specified supply voltage which are simultaneously fed to object of test, in reception of magnitude of tested electric value in the form of output signal of amplifier, in its conversion from analog to digital form. Thereupon digital signal is processed to determine actual magnitude of tested electric value and this magnitude is compared with required magnitude. Automated system testing electric parameters of amplifier includes personal computer, printer, object of test, buffer unit, optron decoupling unit, unit controlling data, unit of address decoder, digital-to-analog converter, unit of control registers, unit of commutator of input signals, unit of commutator of output signals, unit of current pickups, analog-to-digital converter and unit of controlled voltage stabilizer of power supply unit. EFFECT: diminished testing time, enhanced authenticity of test results. 2 cl, 5 dwg
