PRODUCT DETAILS

The Open Workbench Logic Sniffer is an open source logic analyzer with a USB interface. The hardware is designed for the SUMP open source logic analyzer client and toolchain. This project is a collaboration between the Gadget Factory and Dangerous Prototypes.


Features

  • Capture 50MHz+ waveforms on 32 channels

    • 200Msps captures up to 100MHz waveforms on 16 channels

    • 100Msps captures up to 50MHz waveforms on 32 channels


  • 16 buffered channels, 5volt tolerant


  • 216K Block RAM supports following memory configurations*

    • 8 channels with 24K sample depth

    • 16 channels with 12K sample depth

    • 32 channels with 6K sample depth


  • External clock and trigger input

    • Allows interfacing with external test equipment and daisy chaining OLS's for additional channels.


  • Internal clock and trigger output

  • 16bit wing expansion header

  • USB interface, USB powered

  • USB upgradable everything

  • Designed for the SUMP logic analyzer client

  • Open source

  • Low price


Memory depth is the maximum supported by the hardware, the current firmware implements the following memory depths:

  • 8 channels with 16K sample depth

  • 16 channels with 8K sample depth

  • 32 channels with 4K sample depth


Future firmware upgrades will support the maximum memory configurations.

    Sadly obsolete :-( Excellent quality design and manufacture, but sadly this version is now obsolete, there are better solutions out there with far larger capture buffers.

    What were they thinking ? I am still waiting for a wing board. what were the designers thinking when they thought they would save a few pence on a buffer so the end user has to obtain that, some connectors then assemble it into something sensible that doesn't fall apart ?

    Some important signals are only available in the middle of the board.

    Sadly useless I had hoped this would work but I can't get it to be useful at all.
    The hardware appears OK but the software is worthless.
    There are 3 programs that are supposed to work with this:
    1) SUMP - supposedly designed for this board. Has not been worked on since 2008. Needs RXTX that is not compatable with x64 systems. Replacements for RXTX not known to work.
    2) sigrok's PulseView - frequently gives "generic unspecified error" - anyone who writes code that generates messages like that should give up programming.
    3) Open Bench Logic sniffer version 3.08 - ish-works but few decoders. Even then, the sample time is uselessly small.
    I strongly caution against buying this unless you can be sure of finding functional software for it.
