Teardown & repair of the Siglent SHS810 100MHz 1GS/s portable oscilloscope & multimeter

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 […]

I’ve just released the 1.3 version, making it a very credible, user friendly and totally open source alternative to existing soundcard […]

LaserOscope project

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 […]

DIY USB-Oscilloscope in a matchbox

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 […]

App note: Real-time versus equivalent-time sampling

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 […]

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 […]

Experiments and demo of an Agilent DSA-X 96204Q 160GS/s 62GHz oscilloscope

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 […]

A new open source 200MHz logic analyer

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 […]

Oscilloscope USB connection reversed

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 […]

Sparkfun has new oscilloscope

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.

SUMP logic analyzer with 2 scope channels

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 […]

Arduino oscilloscope uses ROS code

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 […]

AVR XMEGA oscilloscope and signal generator

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 […]

Maker Faire 2011: Dangerous DSO

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.
