Design of a Low-Cost Handheld Wireless Oscilloscope

Abstract

Most of the available oscilloscopes are difficult to use, bulky, and expensive. Other challenges of using an oscilloscope include its long setup time, messy wired connections, and an unfriendly interface. To address those issues, in this paper, we propose an original solution, Scopen, a penshaped wireless oscilloscope that is accurate and affordable. By transmitting the captured signals wirelessly and displaying the waveform on the software side, Scopen eliminates cables’ requirements to achieve maximum flexibility. Furthermore, the wireless transmission feature allows us to display the waveform on multiple devices and platforms, increasing flexibility and ease of use. This paper presents Scopen's system target specifications, hardware design that includes a custom printed circuit board, and software architecture. Finally, we will discuss the features and performance of our wireless oscilloscope.
