High-Channel Logic Analyzers
LA4000 vs Saleae Logic Pro 16
Compare the Acute LA4000 68-136 channel logic analyzer with the Saleae Logic Pro 16. Enterprise-grade channel count and cascading vs portable simplicity.
The LA4000 is Acute's high-end logic analyzer platform, offering 68 to 136 channels — an order of magnitude more than the Saleae Logic Pro 16's 16 channels. The LA4000 supports multi-unit cascading, LVDS differential input, and 32 Gb of capture memory. It's designed for ASIC validation, high-pin-count FPGA debug, and system-level analysis where the Saleae simply cannot scale.
