A few wrap-up on the DSO Nano v2 open source fruits!

Free open tool chain

Now Jerry have finished migrating from IAR to GNU tool chain, there is no longer 32Kb code limitation or commercial license concerns! Please join the discussion and try the new compiler from our forum: http://www.seeedstudio.com/forum/viewtopic.php?f=12&t=1262 . Thanks to the help from everybody, especially tormod for providing the new dfuse tool working natively under linux!

Improvements:

  • Proper three phase sampling (pre-fetch, trigger-fetch, post-fetch) guaranteed never to miss infrequent events
    More efficient screen update (10-100 times faster than version 2.5e)
    Eliminate all flickering and stuck pixels
    Code is re-written to allow full compile time optimization (much faster and compact code all over)
    A bug in Vrms calculation is fixed (Vrms is incorrect in 2.5e)
    A number of overflow bugs have been fixed (calculations for large time/div settings)
    Scan has been replaced with a proper continues real-time scan mode
    Configuration profiles can be saved to /restored from SD card or flash (default power on settings).
    Wave data (reference signals) can be saved/restored from SD cards
    Screen capture can be saved to SD bitmap files
    A number of issues with incorrect SD card support and file handling in 2.5e have been fixed
    FIT mode is implemented as a function
    The full captured signal buffer (3000+ points) can be panned left right for further analysis
    A more relevant collection of data is selected for display on screen
    A more relevant selection of measurements
    Simultaneous view of all measurements
    Use proper ISO abbreviations (e.g. milliseconds is “ms” not “mS”)
    A completely redesigned user interface (no annoying blinking or color abuse)
    Support two step calibration (offset and range)

Finally, some new updates of DSO QUAD!

We have finished mold design and moving to trial batch now! They might be ready late this month or early Dec. A few beta units will be open for pre-order. Check out the infant photos of the prototype. The final product will be using different material, expect something neat .

Looks great. Any idea to when it'll be available and its pricing?

3

First batch will available in about 1 month, and i am sure it's price will be very affordable.

Looks and sounds great! Will the sampling speed increase, or is it still at the same level as the current pocket DSO? Also - what about a function generator?

One of these days I plan to buy one of these; it might be useful for field work...

Specs for the quad

  • 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,

Specification:

Bandwidth 36M +36M
4 Channels (2 Digital & 2 Analog)
Waveform output channel (sine wave,triangle waves)
Inside 2M USB flash disk
