Equipment and function testing method for a digital converter, analog and - - analog-to-digital converter

摘要

An inspection apparatus function testing method of a digital converter, an analog - - analog-to-digital converter has a function of converting the at least one digital signal to at least one analog signal with a reference voltage of a predetermined first carrying out, the analog - to the inspection apparatus and function testing method for digital converter, the analog - digital converter, can perform the function using a second reference voltage predetermined at least one alternative available The so formed, the analog - analog-to-digital converter, - and and blocked one reference voltage, to prevent the use of the second reference voltage, particularly at least by a digital converter, in the function test, a predetermined I is characterized in that the analog signal has is converted into a digital signal, the digital signal is evaluated.
