The Apple II’s CPU clock has jitter or a glitch. This issue is not new—it has been present since its original design in 1977! Bald Engineer uses an oscilloscope to show how often the glitch occurs and how to correlate that jitter to its source—which is useful when you are not testing 40-year-old devices. The device under test (DUT) in this video is the Mega IIe project. It’s a fully compatible Apple IIe built around…

Hands down, no questions asked; the MXO 4 Oscilloscope from R&S is the most impressive scope I have ever used. The main reason I say that is because it is FAST. Over the past 20 years, I have worked for 3 of the 4 top oscilloscope companies (always in technical roles.) So I have used almost every major oscilloscope model for the past two decades. Now, regarding oscilloscopes, “fast” can mean a couple of different…

Electronics Tutorial Video Learning to use a new oscilloscope can be daunting! In this video, I show five measurements you can make using just an Arduino as your DUT. Learn how to offset voltage, set up measurements, enable infinite persistence, save reference waveforms, AND trigger (and decode) serial signals. For this video, Rohde & Schwarz was kind enough to send me an RTM3004. Check out the links below for more. Episode #28 Show Notes and…

In part 3 of the DIY Arduino series, James solders, turns on, and, debugs the Pyramiduino!

https://youtu.be/ocN2oTsYIG8 National Instruments (NI), is probably best known for the LabVIEW software and modular instruments. In the past few years, they have introduced more innovative test and measurement products than any other T&M manufacturer, at least, in our opinion. Their latest box is called the “VirtualBench.” It’s a lab’s worth of equipment in a single box at a reasonable price. It combines a DMM, Oscilloscope, Logic Analyzer, Power Supply, and Function Generator into a single…
