Abstract
PURPOSE:To perform high speed measurement reduced in the deterioration of accuracy, by performing the setting of a bias power source and the setting of the measuring range corresponding to the output value of the power source in parallel on the basis of an internally stored corresponding table. CONSTITUTION:A varicap 1 to be measured is energized by a DC bias source 3 through a measuring AC power source 2 and an AC inhibiting apparatus 4 and generates the output corresponding to the applied AC voltage and current of the varicap 1 by a bridge circuit 5. The output is converted to a digital value by an A/D converter 6 and the digital value is subsequently processed by an operation apparatus 7 to calculate a capacity value. The apparatus is controlled by a microprocessor 10 and a memory 11 through a bus 12. The digital signal from the outside is inputted through an interface 13. By this constitution, high speed measurement reduced in the deterioration of accuracy can be performed.
