A Digital Storage Oscilloscope (DSO) Design and VLSI Implementation

Anyone who designs, manufactures, or repairs electronic equipment needs to have access to oscilloscopes. Because of their precision, portability, high resolution, fast speed, data-holding capabilities, and so on, digital oscilloscopes are frequently utilized these days. Oscilloscopes are essential for overcoming today’s difficult measurement issues since they serve as the engineer’s eyes. However, the cost of an oscilloscope is pretty high. In contrast to standard oscilloscopes, which have vast dimensions, the DSO designed and developed in this project will have smaller dimensions. An oscilloscope’s performance is determined by its capacity to measure accurately, its efficiency, how much it costs, and other factors that may be determined by comparing it to other oscilloscopes currently available on the market. Therefore, this manuscript has explained how to design a low-cost, efficient, portable oscilloscope using an FPGA board named Basys-3 from Digilent. The whole system consists of a FPGA board and a monitor only, as shown in Fig. 1. However, we can determine the sort of signal we are receiving by analyzing the flashing pattern of all 16 LEDs on the Basys-3 board, as well as the peak to peak voltage, maximum voltage, and minimum voltage on the monitor. Depending on how much information we need about a signal, we may choose whether or not to use a monitor. To convert the analog input signal and store the signal or waveform in digital representation, the Basys-3 board’s inbuilt xadc and block RAM were employed. The flexibility of this reasonably priced oscilloscope gadget make it appropriate for use as a resource tool for engineering students of circuital branches.
