The NI PXI-6551 is a 50 MHz digital stimulus-response digital waveform generator/analyzer. It features 20 channels with programmable voltage levels and per-clock cycle, per-channel direction control. The module contains deep onboard memory with triggering and pattern sequencing. The latest version of the NI-HSDIO driver software adds the ability to perform on-the-fly comparisons of expected data with acquired response data. With these module features, you can implement a wide range of digital stimulus-response applications, such as functional testing of memory chips and bidirectional communication.
The NI Digital Waveform Editor is an interactive software tool that you can use with NI 6551 devices to quickly and easily create, edit, and import digital waveforms. NI includes the Digital Waveform Editor free of charge with the 8 and 64 Mb/channel models.
For more information on the new ATE features of the high-speed waveform generator/analyzer, read the white paper under the Resources tab.
