DSO QUAD is forming, make a WISH?

By ESP 14 years ago

Seeed Studio and Bure (aka Chai Xiaoguang, the designer of DSO Nano) never stopped improving our oscilloscopes. Now we can introduce you the new model, DSO QUAD.


Comparing to portable easy DSO Nano, QUAD is an intermediate version with more powerful performance and functionality. Target features as below:

  • A first prototype has been made earlier, defining basic structure and functionalities like below
  • 2 Analog channel, 20mV to 10V/div, h36Msps sampling rate, approximate 30Mhz bandwidth, AC/DC coupling.
  • 2 Digital channel, ext. trigger source. Simple AD measurement of 0-5V, DC coupling.
  • 1 Analog signal generator output 10hz~20kHz customizable waveform via DAC.
  • 1 Digital signal generator output 10hz~8MHz square wave.
  • Interface for Bee series/FILM and Electronic Brick Sensors.
  • Internal 2Mb USB storage
  • Designed for hacking, over-clocking, re-purposing, mutants
  • Open source platform with APP store (building)
  • Still compact, wearable(or not), rugged,

This is still an early review of the product, mass production still need at least 2-3 months, target price >150$, trimmed version might be available too. More project info and community comments will be collected on our WISH platform, please feel free to vote, comment or publish your ideas! Participation will be converted to credits on Seeed Depot.

  1. It would be nice if it went up to 15 volts per division. A lot of people do automotive stuff and I can see that being very usefull.

  6. @Adrian the ADC could be clocked on alternate edges, even at current DSO nano.

    The Audio Jack is the best solutions we have found, cheap and portable, shielding is possible. But we are open to any options. 🙂

  7. I would agree with Robokaren – no audio jacks, please. But I think MCX are too fragile and need special fixturing to make, I would prefer SMB.

    Is it possible to clock the ADCs on alternate clock edges ? Then if the same signal were supplied to both, it would be possible to acquire at 72Mhz, giving about 15Mhz useful input bandwidth.

    I don’t care much about signal generators – that’s more useful in a separate instrument. Might come in handy occasionally but if it saves space or cost, I’d gladly lose that feature.

  8. This is great. Some wishes:

    * MCX connectors for the probes instead of audio mini-jacks. Or at least something that is locking and better shielded.

    * Ability to do realtime monitoring via USB.

    * Easier flash upgrading. I’d love to just put an UPDATE.BIN file on the SD card and have the unit flash itself.

    * SDHC card support! 🙂

  9. It would be nice to have a SD card slot and a “take picture” function/button

    I would also like 2mV/div in the lower end of the scale (like the low end Rigol scopes)

  12. Hope to have an UART Scope.
    1.UART input(3.3V or 5V)
    2.Run in terminal mode (show the uart output)
    3.Run in scope mode (Display up to 4 channel of data) (data log from uart use simple cvs format)

  15. Will it still depend on a IAR toolchain? It would be awesome if the source code could be compiled with an open gcc toolchain and a makefile.
