We all love our cheap digital oscilloscopes, and with good reason. But if there’s one place where analog scopes still shine, it’s anywhere you need X-Y mode. Digitally sampling the …read more Continue reading The Right Equipment Makes a Difference for Digital Oscilloscope Music
When debugging something as involved as kernel scheduler timings, you would typically use one of the software-based debugging mechanisms available. However, in cases when software is close to bare metal, …read more Continue reading How Realtime Is Your Kernel? Scope A GPIO To Find Out
[Bart Schroder] was busy designing high voltage variable speed motor drives and was lamenting the inability of a standard scope to visualise the waveforms around the switch transistors. This is …read more Continue reading Isolated Oscilloscope Design Process Shows How It’s Done
For frantic hacking sessions where seconds count, this forearm mounted oscilloscope with fingertip probes built by [aniketdhole] might be just what you need. Well, maybe. It’s not immediately clear why …read more Continue reading Wearable Scope Lets Your Fingers Do The Probing
There has to be more than one of us who over the years since the launch of systems like the original Game Boy have eyed up these handheld platforms and thought “You could make a really neat little oscilloscope with that!” But the commercial systems are closed-source, locked down, and proprietary, so in many cases there’s little easy prospect of such a device being created.
Fortunately though, there are now very accessible handheld gaming platforms, and [James Bowman], the creator of the Gameduino series of boards, writes in to tell us about an oscilloscope project for the Gameduino 3 created …read more
Have you ever found yourself in the need of a nine channel scope, when all you had was an FPGA evaluation board? Do not despair, [Miguel Angel] has you covered. While trying to make sense of the inner workings of a RAM controller core, he realized that he needed to capture a lot of signals in parallel and whipped up this 9-channel digital oscilloscope.
The scope is remote-controlled via a JavaScript application, and over Ethernet. Graphical output is provided as a VGA signal at full HD, so it is easy to see what is going on. Downloading sampled data to …read more
[Martin Rowe] over at EDN recently put a $200 wireless oscilloscope to the test. The Areoscope 100A is a single channel scope in a probe body that communicates back to an Apple smartphone or tablet via Bluetooth LE. You can see the video from the post, below.
The original prototype of the device had a high bandwidth, but the production model only manages to have a 20 MHz bandwidth at 100 megasamples per second: nothing earth-shattering.
We aren’t above having a single channel scope to throw in a bag, but most of the ones we’ve looked at in the past …read more
I’m always on the lookout for a quality addition to my lab that would respect my strict budget. Recently, I’ve found myself pushing the Hertz barrier with every other project I do and hence desperately wanted a high bandwidth scope. Unfortunately, only recently have 70 MHz to 100 MHz become really affordable, whilst a new quad channel oscilloscope in the 500 MHz to 1 GHz range still costs a fortune to acquire. My only option was to find an absolute miracle in the form of an old high bandwidth scope.
It seemed the Gods of Hand Me Down electronics were …read more
It’s not every day that we have the pleasure of being excited about a new oscilloscope in the market; not only is it affordable but also produced by one of the industry’s big players. To top it all off, all the marketing is carefully crafted towards students and hackers.
Keysight recently released a new line of oscilloscopes called the 1000X series that starts at $448. It’s an entry level, two-channel scope having (officially) 50 MHz, 70 MHz and 100 MHz versions to choose from. It hosts their standard technology such as Megazoom, but also some interesting, albeit optional extra quirks …read more
