TL4134B Logic Analyzer

TravelLogic Logic Analyzer

  • PC-based, USB 3.0 interface/powered
  • 800 MHz timing/ 200 MHz state analysis
  • Digital channels : 16 (Data), 1 (Clock), 2 (I²C/DP_Aux)
  • Memory : PC RAM
  • Dedicated interface support: I2C/ DP_Aux, CAN2.0/CAN-FD, RS485
Description

The TravelLogic 4000 series is an upgraded version of TL2000/TL3000, featuring improved memory size and channel counts. It includes both Logic Analyzer Mode and Protocol Analyzer Mode for bus analysis and decoding. This enables TL4134B to support various communication protocols, such as MIPI RFFE and MIPI SPMI.

TL4134B supports MIPI RFFE (Radio Frequency Front-End Interface) and MIPI SPMI (System Power Management Interface); MIPI RFFE is used for data transmission and communication management between radio frequency chips and radio frequency front-end devices. MIPI SPMI, on the other hand, is used for communication between the main control chip and the Power Management Integrated Circuit (PMIC), effectively managing system power.

MIPI RFFE (LA Mode):

Logic Analyzer (LA) Mode
  • Capture digital waveforms and support bus decodes. Able to stack with a DSO to form as an MSO.
  • Provides multiple storage modes, users could select to have long time recording or precision acquisition.

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.
