Concept and experimental evaluation of a novel DC- 100MHz wireless oscilloscope

Abstract

A wireless oscilloscope featuring 100 MHz analog bandwidth and ultra-high isolated measurement channels is presented in this paper. In order to visualize the benefits of this potential-free measurement system, the paper starts with a revision of commonly utilized isolated voltage and current measurement concepts.With a clear understanding of the benefits given by a high-bandwidth, high-isolated and highly common mode immune measurement system laid down, the details about the wireless oscilloscope and its potential-free input channels are presented. Experimental measurements comparing the state of the art isolated voltage and current measurement concepts with the proposed wireless oscilloscope regarding common mode rejection ratio and signal-to-noise ratio are presented, showing the excellent performance of the introduced measurement system.
