TravelBus 3000 series is usually for Vehicle & Automation Industry measurement. It not only supports the common protocols such as I2C etc. but also supports measuring differential signals such as RS485(EIA485)、RS422、CAN2.0、CAN FD、DP-AUX etc. directly. In addition, the TB3000 series is a 2-in-1 analyzer( Logic Analyzer Mode & Protocol Analyzer Mode )

  • 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:

    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.
