Every serious maker out there will surely tell you the importance of having a good oscilloscope. An oscilloscope is something you should have if you really consider yourself a maker, and fortunately enough, the cost of quality oscilloscope has been on the decline for some time now, so you don’t necessarily have to get the big bucker ones to get started.
Small size PC based USB scopes are an excellent alternative, and they do feature a host of capabilities that will give you the performance, accessibility, portability you will need and also cost-effectiveness as a maker. We could possible underestimate the potential of a PC-based USB oscilloscope because of the sheer small size as compared to benchtop versions. But as the processing power available on today’s PCs is increasing, high-end USB PC-based scopes are sprouting out which are increasing rivaling their benchtop partners and even with the advantage of a lower cost.
Not only are PC based scopes significantly easy to use, but the idea of using a PC for the processing means, user can do more with the files, write a custom program to interface with the scope to maximize the full scope potential and many more. In this article, we will mention some lovely USB based scopes (not in any order) for every maker, thinkers, and upcoming electronics engineers.
The Owon VDS1022I is a PC based scope from the Chinese manufacturer Owon that features a 25 MHz bandwidth and maximum 1 GS/s real-time sample rate. The scope is a multi-channel oscilloscope (2+1) channel with a multi-trigger option: Edge, Video, Slope, Pulse, and Alternate. One exciting feature about the scope is that it is capable of displaying two separate waveforms on the same screen.
