TL4234B Logic Analyzer
TravelLogic Logic Analyzer
• PC-based
• USB3.0 interface
• 34 channels
• 2 GHz Timing / 250MHz State Analysis
• 8Gb Memory
• Stacks with Acute or another DSO to form as an MSO
• If you need to perform voltage measurements on SVID or SVI3 simultaneously, you can refer to the MSO3124V
TL4234B combines efficient memory, multi-channel support, and various signal trigger decoding capabilities, including eSPI, SVID, and Ethernet (MII/RMII/RGMII). It is particularly suitable for engineers and technicians in the Intel platform and Ethernet application domains.
TL4234B supports Intel-related signals:
• eSPI: Integrates three bus functions, including SMbus, LPC (used for CPU control of the motherboard”s southbridge), and SerialFlash (used for reading BIOS data).
• SVID: Used for power management.
Additionally, it also supports Ethernet (MII/RMII/RGMII) protocols for data protocol analysis.

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.

Protocol Analyzer (PA) Mode
It is hardware decoding, may log protocol data very long time if without waveforms. Application timing: Preliminary protocol debug.
Protocol Analyzer
Show real-time protocol data. Application timing: massive protocol data with some idles in between.

Protocol Logger
Like data logger, save massive data into SSD hard drive. Application timing: massive protocol data.

Protocol Monitor
Like dash cameras, record protocol data by the device’s memory only. Application timing: trigger event only happens in very long time.
