Selective averaging in an oscilloscope
Average of specific signal components Sometimes, you only want to analyze those signal components that meet certain criteria or occur at certain times within an acquisition. This is not too difficult for a single acquisition, but what if you want to obtain the average of those selected measurement events? Here is where seemingly unrelated features…
Building a low-cost, precision digital oscilloscope – Part 2
Editor’s Note: In this DI, high school student Tommy Liu modifies a popular low-cost DIY oscilloscope to enhance its input noise rejection and ADC noise with anti-aliasing filtering and IIR filtering. Part 1 introduces the oscilloscope design and simulation. This part (Part 2) shows the experimental results of this oscilloscope. Experimental Results Three experiments were…

Basic oscilloscope operation
Whether you just received a new oscilloscope or just got access to a revered lab instrument that you are unfamiliar with, there is a learning curve associated with using the instrument. Having run a technical support operation for a major oscilloscope supplier, I know that most technical people don’t read manuals. This article (shorter than…
Save, recall, and script oscilloscope settings
Introduction Digital oscilloscopes have a great thing going for them: they are digital. Instrument settings, waveforms, and screen images can be saved as digital files either internally or to external devices. Not only can they be saved, but they can be recalled to the oscilloscope or an offline program to review the data and, in…
IndusScope – Smallest IoT Oscilloscope for Wireless Testing
Ossiliscope is an essential test and measurement device that enables us to analyze AC and DC signals, visualize waves, and determine frequency. However, most traditional oscilloscopes are bulky and large in size, which can be inconvenient when working with microelectronics, designing, and testing small components. Therefore, we have designed InduScope, a portable oscilloscope that offers…
