Breakthrough Solutions for Real-time Digital Systems Analysis

The TLA7NAx Logic Analyzer Module speeds debug and verification of fast buses and complex embedded systems with an industry-leading combination of acquisition, triggering and analysis capabilities. Quickly debug fast buses like DDR memory and PCI-X, using long record length to capture intermittent events over a wide time window and MagniVu high-speed timing to simultaneously capture glitches as small as 125 ps. The TLA7NAx module’s advanced triggering capabilities allow you to trigger on microprocessor operation failures, which speeds troubleshooting of embedded systems incorporating microprocessors such as the PowerQUICCIII. Additional tools like source code and protocol analysis and listing view make monitoring and debugging processor operation faster and easier.



Number of Channels (all channels are acquired including clocks) - TLA7NA1: 34 channels (2 are clock channels).

TLA7NA2: 68 channels (4 are clock channels).

TLA7NA3: 102 channels (4 are clock and 2 are qualifier channels).

TLA7NA4: 136 channels (4 are clock and 4 are qualifier channels).

Channel Grouping: No limit to number of groups or number of channels per group (all channels can be reused in multiple groups).

Module "Merging" - Up to five 102 channel or 136 channel modules can be "merged" to make up to a 680 channel module. Merged modules exhibit the same depth and state speed as the lesser of the five individual modules. Word/setup-and-hold/glitch/transition recognizers span all five modules. Range recognizers limited to three module merge. Only one set of clock connections is required.
