Oscilloscope

The Rohde and Schwarz MXO5 is the fastest-performing oscilloscope on the market–even when all 8 channels are active! Bald Engineer checks out the precise trigger, ridiculously fast update rate, and a serial decode feature he missed with his review MXO4 review. Check out what is new with the MXO5, how it compares to the MXO4, and some new features available on both.

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 the Mega II chip.

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 things. First, it could mean the bandwidth is very high. The MXO 4 is a low-to-mid-range bandwidth instrument with options from 200 MHz to 1.5 GHz. So, that isn’t what I mean by fast. Second, it could mean how quickly it starts up. And even though it is a PC-based instrument, it is ready to make measurements in about 45 seconds. But that isn’t what I mean.

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.
