IkaScope: a wireless oscilloscope probe

Author: Maurizio Di Paolo Emilio IkaScope is a wireless oscilloscope probe that allows to observe the change of electrical signals over time. The probe is a handheld device, portable and fits perfectly in the hand and pocket. By using high-speed Wi-Fi connection, IkaScope wireless oscilloscope probe communicates with laptop, tablet or smartphone to share the acquired data on the screen. The IkaScope wireles ...

PC-based Oscilloscope Using Arduino

Oscilloscopes are an essential tool for electronics hobbyists and professionals to verify that their designs would work as expected. PC-based oscilloscopes score over standalone oscilloscopes due to their compact size, low cost and ability to do offline analysis. Here we describe how you can make your own oscilloscope at a very low cost using your PC and an Arduino board as the hardware for signal acquisiti ...

Arduino Based Real-Time Oscilloscope

Arduino Based Real-Time Oscilloscope The Oscilloscope is one of the most important tools you will find on the workbench of any electronics engineer or maker. It is primarily used for viewing waveform and determining voltage levels, frequency, noise and other parameters of signals applied at its input that might change over time. It is also used by embedded software developers for code debugging and technici ...

Review: Siglent SDS 2304X oscilloscope

I’ve had a Siglent SDS1102CML two channel 100 MHz bench scope here for the last two years. I demand a lot from my test equipment so had low expectations when it arrived. After all, how good can a $359 unit be? Turns out, quite a good for the price. I reviewed it here. But the screen is smaller than most modern pro scopes with lower resolution than many would like. And 100 MHz just doesn’t cut it for a lot o ...

Project curve tracer – progress update

As the hardware is at the point of initial release, but the firmware and GUI aren't quite there yet, I decided that it would be prudent to split off the firmware and GUI components into their own GIT repositories. Tracking all files in the same repository was convenient through the initial stages of project development, but splitting them allows for more targeted releases and will likely make contributions ...

An almost-GHz active differential oscilloscope probe

I wanted to probe a PCB at work to see how a ~500MHz differential clock was behaving. My trusty 100MHz oscilloscope was no use, it was too slow to see anything and unfortunately I couldn’t quite justify buying a $3k differential probe for my faster scope just for this. There are a bunch of DIY probes to be found on the internet but none that seemed to work really well. But then I thought “how hard can it be ...

Eye Diagram Basics: Reading and applying eye diagrams

Accelerating data rates, greater design complexity, standards requirements, and shorter cycle times put greater demand on design engineers to debug complex signal integrity issues as early as possible. Because today's serial data links operate at gigahertz transmission frequencies, a host of variables can affect the integrity of signals, including transmission-line effects, impedance mismatches, signal rout ...

Rigol DS1000Z & DS2000 Oscilloscope Jitter Problems

Dave investigates two very serious issues with jitter on the Rigol DS1000Z series oscilloscopes, including the DS1104Z and new DS1054Z Some sort of modulated sampling/trigger jitter problem at 5 microsecond intervals (the “5us jitter problem”). And severe jitter with the AC coupled trigger mode, a problem which is also present on the DS2000 series scopes as well.   For more detail: EEVblog #683 – Rigol ...

Wireless Arduino Oscilloscope

In this guide I will explain how to use a Windows 8.1 phone, Arduino Uno board, and HC-05 Bluetooth module to build a wireless oscilloscope. The phone application has the critical functions of an oscilloscope, although the bandwidth is a measly 300 Hz. Still, if you want to see squiggly lines on your phone, it is a fun project. Today's phones have the ability to perform real-time signal processing. The chal ...
