Features

  • Fully integrated data converter test solution
  • Sample rates from DC up to 200MHz

  • Coherent measuring by default
  • Flexible and versatile digital IO
  • Extended Analysis software included
  • Static, Dynamic and Histogram testing
  • Lua script for easy user test implementation

The ATX-Express is a fully integrated solution for testing ADCs, DACs and other Analog functions. It features the same signal quality and versatility as the ATX7006, but is limited to 5 slots. The ATX-Express is ideal for test labs that don't have a wide range of converters to test and therefore can settle with less slots. The ATX-Express is a single instrument for testing data converters. This saves the investment in various high end rack and stack instruments and writing proprietary software to control them.

This means you can concentrate on testing your converters rather than fine-tuning the test set-up. The ATX-Express is capable of testing converters from 4 to 24-bit. Its versatile digital I/O makes interfacing to the DUT easy, even for embedded converters. The Single Reference Architecture improves the stability and reduces calibration effort. The backplane distributed clock ensures coherent measuring.

The ATX-Express can also be used as an add-on upgrade for ATE systems. Please see the ATX7006 documentation for more details.
