Breakthrough Solutions for Real-time Digital Systems Analysis

Today's digital design engineers face daily pressures to speed new products to the marketplace. The TLA7N4 logic analyzer module answers the need with breakthrough solutions for the entire design team, providing the ability to quickly monitor, capture and analyze real-time digital system operation in order to debug, verify, optimize, and validate digital systems.

Hardware developers, hardware/software integrators, and embedded software developers will appreciate the range of capabilities of the TLA7N4 logic analyzer module. Its broad feature set includes capturing and correlating elusive hardware and software faults; providing simultaneous state and high-speed timing analysis through the same probe; using deep state acquisition to find the cause of complex problems; real-time, nonintrusive software execution tracing that correlates to source code and to hardware events; and nonintrusive probing.

The TLA7N4 logic analyzer module offers Tektronix' breakthrough MagniVu™ technology for providing high-speed sampling (up to 2 GHz) that dramatically changes the way logic analyzers work and enables them to provide startling new measurement capabilities.

The TLA7N4 module offers high-speed state synchronous capture and high-speed timing capture through the same set of probes. It capitalizes on MagniVu technology to offer 500 ps timing on all channels, glitch and setup/hold triggering and display, and time stamp that is always on at up to 500 ps resolution.

The TLA7000 Series logic analyzer modules are ideal for timing analysis, multiprocessor/bus applications, and embedded software analysis.
