| Teaching alternating currents, ac or sound waves, is incomplete without an introduction to the oscilloscope. An oscilloscope is a tool that graphically displays electrical signals and shows their time dependence. However, due to the pandemic, triggered by the SARS-CoV-2 virus, many students do not have the opportunity to master the use of an oscilloscope. Face-to-face teaching activity has been interrupted in both schools and higher institutions. The sudden change to online teaching created problems among educators, especially for laboratory activities. The central issue is creating laboratory activities without going into the labs for the students to acquire the required skills, especially the basics of how to operate an oscilloscope. In order to create an opportunity and engaging environment, we suggested the use of the web-based and stand-alone oscilloscope. The software consists of a low-frequency (signal) generator (LFG), a direct current power supply, and an oscilloscope. The LFG is capable of producing several types of signal and the software is designed to aid the undergraduate engineering and physics students in learning the operation and functions of a digital storage oscilloscope. It can be used as an alternative to face-to-face laboratory activity for physics experiments. It is free and easy to use. The experiments enable students to develop the experimental and measurement skills related to signal generators and oscilloscopes. Hence it opens the opportunity of doing virtual physics investigations individually at home. 2022 IOP Publishing Ltd. |
