Features & Benefits

  • Performance and Ease of Use to Debug, Validate, and Optimize Digital Systems
    • 40 ps Resolution MagniVu™ Acquisition to Accurately See Signal Relationships in Your System
    • State Speed – Sample your fastest synchronous buses with clock rates up to 667 MHz and data rates up to 1333 Mb/s
    • 15 in. Display, with Optional Touch Screen to See More of Your Data and Navigate Efficiently through Your Data
    • 4 Models with 34/68/102/136 Channels and Up to 64 Mb Record Length offer Flexible Solutions to Fit Any Budget
    • Drag-and-Drop Triggering – Simply drag any one of eight different trigger types from a table onto the waveform and the TLA will automatically set up the trigger conditions. Eliminates errors, improves repeatability, and saves time
    • Drag-and-Drop Measurements – Simply drag an icon from the measurement toolbar and drop it on your signal of interest and get a table of results. Saves time, removes complexity, and reduces measurement uncertainty
  • Comprehensive Set of Signal Integrity Tools that Allow You to Quickly Isolate, Identify, and Debug Complex Signal Integrity Issues
    • Glitch Trigger and Storage – Allows you to trigger on and highlight potential signal integrity problems. Not only can the TLA6400 Series trigger on the problem, but by highlighting suspected problems in red, you will be able to easily determine which signals you need to investigate further
    • iCapture – Route the suspected signal to the analog output of the TLA6400 Series using the exclusive Tektronix iCapture feature. This eliminates the need to double-probe with an oscilloscope probe, reducing time to debug
    • iView – Time-correlated view of both logic analyzer and oscilloscope data to trace the SI problem across the digital and analog domain


  • Digital Hardware Validation and Debug
  • Monitoring, Measurement, and Optimization of Digital Hardware Performance
  • Embedded Software Integration, Debug, and Verification

Efficiently Debug and Validate Your Digital System at a Price You Will Like!

The affordable TLA6400 Series of logic analyzers offer the performance needed to debug, validate, and optimize the functionality of your digital system. The TLA6400 Series also provides a comprehensive set of signal integrity debug tools that allow you quickly isolate, identify, and characterize elusive and hard-to-find problems. Add a broad range of support for today’s applications, and you have the ideal tool to help you meet all of the debug challenges of today’s digital designs.

The TLA6400 Series allows you to effectively validate and debug the functionality of your digital designs:

  • Use the patented 25 GHz MagniVu technology to accurately measure timing relationships. The single, integrated acquisition architecture of the TLA6400 Series eliminates the timing skew problems inherent in other logic analyzer architectures
  • Capture on buses with clock rates up to 667 MHz and data rates up to 1333 Mb/s
  • Buy the capability you need now and upgrade as your measurement needs grow
  • Quickly isolate events through a simple and intuitive drag-and-drop trigger setup
  • Easily summarize your design’s performance with sophisticated drag-and-drop measurements such as frequency, period, pulse width, duty cycle, and edge count
  • View data in a variety of time-correlated formats including waveform, listing, graph, disassembly, source code, or compare

Find Tough Signal Integrity Problems

Today’s logic analyzers not only need to help troubleshoot functional issues in your design, but also need to help find signal integrity problems caused by crosstalk, termination mismatches, ground bounce, and other issues. To help debug these problems, the TLA6400 Series includes a comprehensive suite of signal debug tools.

These tools allow you to:

  • Use glitch trigger to monitor selected signals in your design and trigger when a signal integrity problem is found on any one of these signals
  • Automatically tag any found signal integrity problems, allowing you to quickly identify the signals of interest
  • Gain more insight into the problem using the exclusive iCapture functionality to view both digital and analog data through a single probe
  • Use iView to see time-correlated digital and analog displays of your data, letting you track the signal integrity problem across both analog and digital domains
