Recreating Fast Oscilloscopes is a Slow Process

If you want to do something you’ve never done before, there are two broadly-defined ways of approaching it: either you learn everything you can about it and try to do it right the first time, or you get in there and get your hands dirty, and work out the details …read more

Solving The Mysteries Of Grounding While Improving A Power Supply

Grounding problems and unwanted noise in electrical systems can often lead to insanity. It can seem like there’s no method to the madness when an electrical “gremlin” caused by one of these things pops its head out. When looking more closely, however, these issues have a way of becoming more …read more

OWON Oscilloscope Teardown

We sympathize with [learnelectronic’s] statement: “I’m ashamed. I may have bought another oscilloscope.” We get it and we enjoyed watching him tear down the OWON SDS1102. (Video, embedded below.) As you might guess, this is a 100 MHz, two-channel scope, and very similar to many other Chinese scopes you can …read more

How To Design A Low Cost Probe-Oscilloscope

[Mark Omo] sends in his write up on the design of what should hopefully be a sub-$100 oscilloscope in a probe. 

Many problems in engineering can be solved simply by throwing money at the them. It’s really when you start to apply constraints that the real innovation happens. The Probe-Scope …read more

You Don’t Need That Bulky CRT Oscilloscope Anymore

While it might be nice to use a $4,000 oscilloscope in a lab at a university or well-funded corporate environment, a good portion of us won’t have access to that kind of equipment in our own home shops. There are a few ways of getting a working oscilloscope without breaking …read more

glScopeClient: A Permissively-Licensed Remote Oscilloscope Utility

One of the most convenient things about modern digital oscilloscopes is that you can access the recorded data on a computer for later analysis, advanced protocol debugging, or simply the convenience of remote capture. The problem is that the software isn’t always ideal. Vendor-supplied utilities are typically closed-source and they …read more

Repairing And Upgrading A HP 16533A Scope Card

In the world of oscilloscopes, as in the rest of the test equipment world, there’s always some trickery afoot. Companies will often offer different models to the market at different price points, in an effort to gain the widest possible customer base while also making the most profit. Cheaper, less …read more

Grab an Image From Your O-scope The Easy Way

The Rigol DS1054Zed is the oscilloscope you want. If you don’t have an oscilloscope, this is the scope that has the power and features you need, it’s cheap, and the people who do hardware hacks already have one. That means there’s a wealth of hardware hacks for this oscilloscope. One …read more

Talk To Your ‘Scope, And It Will Obey

An oscilloscope is a device that many of us use, and which we often have to use while our hands are occupied with test probes or other tools. [James Wilson] has solved the problem of how to control his ‘scope no-handed, by connecting it to a Raspberry Pi 3 running …read more

Break Your Scope’s Bandwidth Barrier

Oscilloscope bandwidth is a tricky thing. A 100 MHz scope will have a defined attenuation (70%) of a 100 MHz sine wave. That’s not really the whole picture, though, because we aren’t always measuring sine waves. A 100 MHz square wave, for example, will have sine wave components at 100 MHz, 300 MHz, and the other odd harmonics. However, it isn’t that a 100 MHz scope won’t show you something at a higher frequency — it just doesn’t get the y-axis right. [Daniel Bogdanoff] from Keysight decided to think outside of the box and made a video about using scopes …read more
