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 (in progress)
  • Still compact, wearable

    Wait…so, is this http://www.sparkfun.com/products/10388 the DSO Quad on this page?

    So much want for this right now… I’m actually considering holding out on getting a DSO Nano v2 and waiting for this to finally be available. The dual channel really sets it.

    I’d totally buy one of these! It would be nice is the actual analog bandwidth instead of just sample rate were listed, a lot of people are confused and reselling these (pre-order of course) with the wrong stats- check ebay; dso quad

    Looks really good so far.

    Can’t wait to get the beta device. Which FPGA will be used?

    Would be pretty neat to combine it with something like the bus pirate does for digital signals and decode them. The probe interface looks new and I hope it means we can use some more standard probes. The DSO nano probes are pretty weak. Also, you might want to hire Ben on to help out with the coding for the release, I’m sure he’d be happy to help out for the cost of product.

    When will it be out selling?

    Can the USB handle the full sampling rate of all four channels at full bandwidth? If it can then a streaming mode might make sense. If it can not keep up then the current reliable code BenF did is sufficient. Half of the time I am using a OLS I am only looking at a few signals. (If I really need to look at a wide bus I fire up the old HP analyzer I have that can handle 64 plus pins.)

    For view i2c/spi, serial, or analog inputs and a control signal or two this would do nicely if it could stream and have a deeper memory than the OLS.

    You may consider implement RS232 reading. for example, enter in RS232 function, and connect it to any RS232 source, and display in the screen the characters received.

    It would be nice for testing PC interfaces

    Add link to a PC for more advanced processing and/or larger display area.
