Tektronix TLA6404 136-channel Logic Analyzer Module,

The Tektronix TLA6404 is a 136-channel logic analyzer module that captures and analyzes digital signals across embedded systems, digital hardware designs, and software-hardware integration tasks. It delivers timing resolution to 40 ps via MagniVu™ technology alongside state acquisition at 333 MHz standard, supported by up to 64 Mb of expandable memory. The module combines deep acquisition capability with flexible triggering and signal integrity analysis to isolate complex timing and behavioral issues in digital systems.
