TravelLogic 4000 series is an upgrade version of TL2000/TL3000. It has improved the memory size and channel counts. And it contains Logic Analyzer Mode and Protocol Analyzer Mode for bus analysis and decodes.

  • Logic Analyzer(LA) Mode
    Capture digital waveforms and support bus decodes. Able to stack with a DSO to form as an MSO.

    LA Storage Mode:

    Storage mode
    Long Time Record: Transitional Storage VS Compressed Storage
    For signal capture and analysis, usually require to record the signal for a long time. If the data is stored in a compressed way, it will cause your software to lag or even stop functioning when decompressing the data after it is sent back to the computer. Because PC memory size might insufficient for decompressed data size. To satisfy the requirement of smooth software operation and long-term recording without missing any data, the storage method adopted by the Acute analyzer is transitional storage rather than compression. After returning to the PC software, it doesn't need to do the decompression. The decoded results can be displayed while the analysis is finished.
