Abstract
PURPOSE: To measure various kinds of input voltage without interruption by generating a voltage level by use of a memory of selective information, a voltage level data memory part, and a digital-analog converter.
CONSTITUTION: The voltage level generator 5 which has been connected to the control part 2 of the central processing unit 1 is provided with the momory 12, the memory 13 and the digital-analog converter 11, and its output is connected to the pin electronics. When a test pattern Pn of the word address (n) is being read out from the pattern generation part 4, the contents of the selective information b1Wbm indicated by the word address (n) in the same way are applied to the memory part 12, and the voltage level of the digital-nanlog converter 11 is decided. In this way, it is possible to vary the voltage level of the digital-analog converter 11 by the test pattern in accordance with the selective information b1Wbm.
