Summary: | This paper deals with a design and construction of a dual-channel oscilloscope interface which enables concurrent measurement of voltage and current waveforms up to 30 kHz. The operation of the unit is based on a capacitive coupling through and isolation barrier inside a custom integrated circuit. The construction is cheap and easy to be bulit. Two samples of the device were bulit and tested at certain service operations. Based on the experience, several modifications have been proposed. These proposals are included in this paper as well. © 2014 North Atlantic University Union. All rights reserved. |
