A Digital Storage Oscilloscope stores and analyses every signal digitally rather than using analogue techniques. Oscilloscopes which are currently available in market like Cathode Ray Oscilloscope (CRO) or Digital Storage Oscilloscope (DSO) are expensive, consume more power and are bulky. Many portable devices, such as tablets and smartphones, support the Android Operating System and are capable of composing a Graphical User Interface(GUI) for a DSO, through an application. If a DSO application is designed, the desired waveform can be seen directly on mobile. The Android Operating System (OS) is constantly attaining more interest of developers throughout the globe. Android based DSO presents the design and implementation of a low cost, portable, light weight, low power, single channel DSO. Signals having frequency between 0-100Hz and amplitude 0-10V can be measured. It has 3 modules: Advanced Virtual RISC (AVR) interface, Espruino (ESP) module and Android application. To perform the necessary actions and to understand the actions taken by the user, an intelligent device like a microcontroller, ATMega16L is used. ESP8266 offers a complete and self-contained Wi-Fi networking solution, which sends the samples of data wirelessly to the application on mobile. The application is developed having the same display as that of a DSO. The user will be able to observe the waveforms and also control them by buttons given on the screen. D0epending on the data samples the corresponding waveform is plotted on the GUI. This paper summarizes the implementation of a portable DSO module with a GUI using an Android application.
