Overview
Acute Technology LA4000 Series Logic Analyzer
The Acute Technology LA4000 Series is a PC-based logic analyzer designed for demanding signal analysis and protocol debugging applications. With up to 136 channels and sample rates reaching 4 GHz timing and 400 MHz state analysis, it meets the requirements of complex digital designs, including FPGAs, ADCs, and advanced communication interfaces. The series offers models such as LA4068B/E and LA4136B/E, providing both 68 and 136 channel options tailored to your application's needs. A 32 GB memory depth supports extensive data capture for long or critical events, and the device connects via USB 3.0 for reliable, high-speed data transfers.
Engineers benefit from wide protocol support, enabling analysis and decoding of over 100 protocols like I²C, SPI, CAN, UART, and newer standards including eSPI and MIPI I3C. Unique trigger and storage options, such as parallel clause triggers and real-time protocol monitoring, facilitate fast troubleshooting and deep debug insight. The LA4000 can stack with oscilloscopes from leading brands, expanding it into a powerful mixed-signal verification tool.
For those looking for performance above rivals like Saleae, Tektronix, and Agilent/Keysight, the LA4000 stands out with higher channel count, broader memory and robust voltage range—making it ideal for capturing rare, high-speed faults across large embedded systems. Compatible with LA3000+ probes, it eases upgrades and preserves your hardware investment.

Questions and Answers
-
What Is the Acute Technology LA3000 Plus Series Logic Analyser?
The LA3000 Plus is a PC-based logic analyser from Acute Technology Inc. for analysing digital signals and protocols in electronic systems. Its features include:
- 68/136 channels
- USB 3.0 interface
- 2.4GHz timing analysis and 300MHz state analysis
- 32Gb memory
- active probe
- logic, state and protocol triggers
- over 100 bus decodes
It runs on Windows 7, Windows 8, Windows 10 (64-bit) and Windows 11. The PC needs a USB 3.0 port and at least 8GB RAM (16GB recommended).
-
How Many Channels Does the LA3000 Plus Have?
The LA3000 Plus logic analyser has 68 or 136 channels, depending on the model (LA3068: 68, LA3136: 136).
-
Can I Set a Trigger on a Bus Protocol State?
Yes. The LA3000 Plus supports Bus Trigger I (I²C, MIPI I3C 1.1, SPI, UART (RS232), USB PD 3 and others) and, on B+ models, Bus Trigger II (eMMC 5.0, eSPI, NAND Flash, SD 3.0, Serial Flash, SVID and others), so you can capture specific events or conditions on the bus.
-
Which Communication Protocols Does the LA4000 Support?
The LA4000 series decodes over 100 protocols. These include I²C, SPI, CAN 2.0B/CAN FD and USB PD 3, plus high-speed protocols such as eMMC 5.1 and NAND Flash. For custom or proprietary protocols, Acute offers a Protocol Decode SDK for writing your own decoder DLLs.
-
Can the LA4000 Be Integrated with Other Test Instruments?
Yes. The LA4000 series stacks with oscilloscopes from Acute, GW Instek, Tektronix, Keysight/Agilent, LeCroy, HAMEG and R&S.
Link the trigger ports with the BNC-MCX cable and connect the oscilloscope to the PC over USB or LAN; the pair then works as a mixed-signal oscilloscope (MSO) with synchronised digital and analogue signals.
-
What Are the PC System Requirements for the LA4000?
The LA4000 needs a PC with:
- Windows 7, 8, 10 or 11 (64-bit versions only)
- a USB 3.0 port
- at least 8GB RAM (16GB recommended)
