LA4000 Series

Q: Can I get a demo or evaluation unit of the LA4000 Series?

Yes. Contact our engineering team at support@acutena.com or call +1 (415) 409-8771 to discuss evaluation options for your application.

High-performance 68–136 channel logic analyzers with 4 GHz timing, 400 MHz state analysis, and 32 Gb memory. Supports multi-unit cascading and optional LVDS differential input.

The LA4000 series is built for high-channel-count applications — IC validation, FPGA I/O testing, and multi-bus system debug. Available in 68 and 136-channel configurations with 4 GHz timing analysis and 32 Gb memory. Tier I and Tier II models offer progressively deeper protocol trigger support for storage, computing, and power interfaces.

68 or 136 channels per unit with 4 GHz timing
Multi-unit cascading for expanded channel count
Optional LVDS input pod for high-speed differential signals
Windows 10/11 + native Linux app (beta)

Key Capabilities

Device Cascading

Cascade up to 16 Acute instruments for 64+ synchronized channels of logic analysis — scale your channel count to match your design complexity.

Third-Party DSO Stacking

Stack Acute logic analyzers with popular third-party oscilloscopes for time-correlated analog and digital capture in a single view.

Streaming Mode

Capture continuous protocol data to your PC's storage — monitor buses for hours or days without missing a transaction.

Power Sequence Validation

Validate power-up and power-down rail sequencing across 16 to 128 channels simultaneously — critical for multi-rail FPGA and SoC designs.
