DSO Quad – Aluminum Alloy now is available at Seeed Studio. A new, rigid, elegant aluminum alloy shell makes the Quad even better. This is the coolest tool you should have on your worktable!

DSO Quad is a pocket size 4 channel digital oscilloscope for common electronic engineering tasks. It's based on ARM cortex M3 (STM32F103VCT6) 32 bits platform, providing 72MS/s sampling rate with integrated FPGA and high speed ADC. Internal 2MB USB disk could be used to store waveform, user application and upgrade firmware.

Note: Due to the metal conductive shell of DSO Quad, its operating voltage should be controlled under 60V during working in case of any damage to the Quad itself or human.

  1. Product Quality
    The device is working, Started the calibration procedure and discovered that it is already calibrated! Good job.
    It would be nice if you put somewhere the firmware files of the current version - to have them at hand in case of emergency.
