Headless Connected Oscilloscope based on Cubieboard or Beaglebone

Warsaw ELHEP (Electronics for High Eenergy Physics Experiments) Group is currently working on MMS (Mobile Measurement System) Project. This project features what I would call a “headless connected oscilloscope”, which can be detected on the network via SSDP, send the data via Websocket, and display it on iOS, Android, or Windows Phone devices. This oscilloscope does not feature any screen, and receives/transmits data via Ethernet, Wi-Fi, or Bluetooth. The original hardware is based on three main boards: CTI-VMAX – ARM9 with Wi-Fi, Bluetooth, and Ethernet connectivity. ARM SCOPE v1.0.1 with  8 channel ADC. ARM SCOPE v1.0.2 with 4 high speed ADC (100MSPS). The ELHEP researchers have been looking at replacing CTI-VMAX with low cost boards, and after considering several options, they chose to design two versions of their oscilloscope: one based on Cubieboard, and the other on the Beaglebone. So they designed expansions boards for the Cubieboard and Beaglebone in […]

199 USD Seeed Studio DSO Quad Open Source Oscilloscope

The DSO (Digital Storage Oscilloscope) Quad is a pocket size 4 channel digital oscilloscope for common electronic engineering tasks based on STM32F103VCT6 ARM cortex M3 MCU with a 3″ display. It can provide 72MS/s sampling rate with integrated FPGA and high speed ADC and an internal 2MB USB disk can be used to store waveform captures, user applications and to upgrade firmware. SeeedStudio DSO Quad is not exactly a new product (June 2011), but I was not aware of this type of low cost oscilloscopes until I come across a review today. Here are the key features of this tiny oscilloscope: Pocket size and light weight Two 72MS/s analog channels, plus two digital channels Signal Generator Auto Measurement Various Triggering Option Easy waveform storage Firmware upgrade User applications Open source and technical specifications: 2x Analog channel: [CH A]  [CH B] 2x Digital channel :   [CH C]  [CH D] Vertical […]
