Here’s a teardown & repair of the Siglent SHS810 100MHz 1GS/s portable oscilloscope & multimeter from The Signal Path: In this episode Shahriar examines the failure of a Siglent SHS810 100MHz 1GS/s portable oscilloscope and multimeter. The instrument’s multimeter inputs are functional, however the neither of the oscilloscope inputs display the correct waveform. The displayed […]
D4p0up shared his open source soundcard oscilloscope in the project log forum: Here is a tool that might help some of you in your DIY activities : WaveWatch, a soundcard oscilloscope 100% made with Processing. I’ve just released the 1.3 version, making it a very credible, user friendly and totally open source alternative to existing soundcard […]
Steve Schuler over at Science2.0 published a new build: A laser oscilloscope using Lego, littleBits, Erector set, and the Kano Computer Build a laser oscilloscope using Lego, littleBits, Erector set, and the Kano Computer. In honor of The International Year of Light I’ll demonstrate how use the Kano computer to drive a littleBits motor with an […]
ajoyraman posted a tutorial on how to make a DIY USB-matchbox oscilloscope, an instructable here: In order to economize on the cost of an enclosure while still providing an aesthetic unit the Aj_Scope2 is enclosed in a large size cardboard matchbox enclosure. The USB connection to the PC is on one end while the Audio-Jack […]
Real-time versus equivalent-time sampling (PDF!), an app note from Tek: When a DSO uses equivalent-time sampling, it can acquire any signal up to the analog bandwidth of the scope regardless of the sample rate. In this mode, the scope gathers the necessary number of samples across several triggers. The input signal must be repetitive to generate […]
Bruce Land writes: Turns out that the DMA channels on a PIC32 can move data from the ADC using the ADC done interrupt flag, but without wasting time in an ISR. The ADC can be triggered by a timer interrupt flag, again without software intervention. Doing this means that you can blast ADC into memory […]
Jan Henrik wrote this Instructable detailing the build of his DIY USB oscilloscope with signal generator: In this project I want to show you how to make an easy and cheap USB Oscilloscope. Specifications: Price: 20$ Frequency: 2-20000HZ Resolution: 16 Bit Voltage range: +-7V / with probe +-70V Channels: 2 X-Y Mode Signal generator: Sine, Square, Triangular and Sawtooth […]
Shahriar writes: In this episode Shahriar demos the world’s fastest oscilloscope! The Agilent DSA-X 96204Q offers 160GS/s of conversion rate with a bandwidth of 62GHz on two dedicated ‘RealEdge’ channels. It can also provide 80GS/s conversion rate and 33GHz of bandwidth on four simultaneous channels. The unit demoed in this video is equipped with all […]
Here’s an interesting open source 200MHz logic analyzer project on Kickstarter, the DSLogic by DreamSourceLab: DSLogic consists of DSLogic-Core and extension modules. DSLogic-Core is a re-configurable circuit board based on FPGA technology with maximum 200MHz sampling rate and 64Mbit on-board memory. DSLogic-Core can work alone as a fully functional logic analyzer, along with various extension modules.DSLogic can also […]
Raul from Coding Laboratory has designed a DIY ECG project using an Arduino and Xoscillo: To display the wave I am using XOSCILLO, a very cool and open source tool (which I wrote :P) that converts your Arduino into an oscilloscope.
Mick bought and disassembled a Tektronix 465 oscilloscope. It’s a 100 MHz dual trace, dual timebase analog scope. He points out that most of the transistors are socketed instead of soldered. More pics below. Via the forum.
András Veres-Szentkirályi is part of the H.A.C.K. hackerspace in Hungary. They acquired an affordable, slightly used UNI-T UT2025B digital storage oscilloscope. He wondered what useful information could be gained from sniffing the USB port using Wireshark on a Linux box. Andras writes: I managed to reverse engineer the USB connection of the Chinese digital storage […]
Sqkybeaver let us know Sparkfun now carries a scope similar to the one he reviewed. It is a two channel 100MHz digital scope with 500MSa/s real-time sampling rate. Saving waveforms to a USB flash drive is available, as well as interfacing with the computer over the USB port. The waveforms and menu are displayed over a 5.7″ LCD Screen. Via the forum.
Pong on an oscilloscope. Check out Kevin’s epic original project over at Hack a Day: Want to play Pong on your Oscilloscope? I always have! …The code is a nice mixture of ArduincoreGCCish (I am sorry, still learning), and includes the following demos: Simple low resolution dot drawing A font example A very quickly and […]
hlipka made a logic analyzer with 2 oscilloscope channels that uses a Cypress PSoC chip. It works with SUMP clients like Open Logic Sniffer. Goal of this project is to develop a combination of 2-channel oscilloscope with a 32-channel logic analyzer. Sample speed will be 1 Msps, with a depth of 6k samples (when using […]
Ros.org presents this project tutorial demonstrating that a simple oscilloscope can be implemented using the Arduino. They write: In this tutorial, we will be making a poor man’s oscilloscope using the Arduino’s ADC (analog to digital converter) and rxplot. We will set up a publisher which will forward the analog values from each of the […]
Squonk has some useful links if you want to build your own scope: A nice HDL example of an oscilloscope using a FIFO and trigger A 100 MHz input stage A firmware development/improvement for the DSO “Welec 2000a- series” The (sad) story about the DSO Quad portable scope (why sad?) Thanks Squonk! Via the forum.
bearmos found a multifunction MSO: …it appear to be an MSO, with an OLED display, in a DIP package, for $35 The Xprotolab is the first mixed signal oscilloscope with an arbitrary waveform generator in a DIP module. It measures only 1 x 1.6 inches, and can be mounted directly on a breadboard. The Xprotolab […]
Dangerous DSO is a new logic analyzer/oscilloscope prototype we’ve been using in the lab. It combines a 16 channel logic analyzer with one 50MHz oscilloscope channel with +/-10volt DC range. The combined tool shows what your signal does between 0 and 1, which helps pinpoint noise and other electrical glitches.
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. This week we’re giving away two […]
