Acute LA4000 Logic Analyzers Add Stacking, Scaling to 256 Channels

Multi-unit stacking delivers a flexible, cost-effective path to large-scale digital measurement for SoC validation and embedded system debugging

New Taipei City, Taiwan — July 14, 2026 — Acute Technology Inc., a Taiwan-based test and measurement instrument manufacturer, today announced stacking support for its LA4000 series logic analyzers. By stacking multiple LA4136 series units, engineers can now expand their measurement setup to a maximum of 256 channels with a top sampling rate of 250MS/s in stacked mode, delivering a flexible and cost-effective solution for SoC validation, embedded system debugging, and large-scale digital circuit measurement.

As electronic designs grow increasingly complex, engineers frequently run into the limits of single-unit channel counts. The LA4000 series offers 68 or 136 channels per unit; with the new stacking capability, users can scale their channel count as projects grow — without replacing existing equipment — protecting their instrument investment.

LA4000 Stacking — Key Specifications:

• Maximum sampling rate: 250MS/s (stacked mode)
• Maximum channel count: 256 channels
• Acquisition mode: Asynchronous (timing) mode
• Trigger modes: Free Run, Single Level, External
• Cross-model stacking: Mixed stacking supported within the LA4136 series (e.g., LA4136E stacked with LA4136B)

Notably, stacking works across different models within the LA4136 series, so users can freely combine existing LA4136E and LA4136B units rather than being locked into a single model — significantly improving equipment utilization. Combined with the LA4000 series" existing capabilities — 4GHz timing analysis and 400MHz state analysis in single-unit operation, USB 3.0 connectivity, more than 100 protocol decoders, and mixed-signal measurement through oscilloscope stacking with instruments from Keysight, R&S, Tektronix, and others — the LA4000 series now offers a complete measurement platform from bench-level debugging to large-scale system validation.

The LA4000 stacking feature is available now. For detailed specifications and software downloads, visit www.acute.com.tw or contact your regional distributor.
