The LA4000 series offers superior performance in both timing analysis and state analysis compared to the LA3000+. The LA4000 model achieves a frequency of 4 GHz in timing analysis and an impressive 400 MHz in state analysis, making it an ideal choice for logic analysis in high-speed data transmission, communication protocol analysis, and handling complex signal structures.

The LA4064B logic analyzer is a versatile tool, providing comprehensive support with its 68 channels. It addresses various application scenarios, from analyzing signal structures to decoding and debugging communication protocol buses. Commonly used in the development and debugging of ADC and FPGA chips, it provides robust support for signal analysis, communication protocol decoding, and bus analysis.

The LA4000 series also supports stacking measurements with various oscilloscopes through the MCX to BNC cable, facilitating seamless connections with oscilloscopes from other brands such as Keysight, R&S, Tektronix, Acute TravelScope, and more.

Whether in applications requiring high-speed timing analysis or dealing with complex state analysis, the LA4000 series proves to be a reliable partner, offering robust support and versatile applications for your measurement tasks.

• 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.
