Using the NI 655x for Logic Analyzer Applications

During the process of debugging and validating a digital system, a common task is the acquisition of digital waveforms. A logic analyzer is a tool that allows numerous digital waveforms to be acquired simultaneously. The acquisition can be clocked internally, or the System Under Test (SUT) can provide the sample clock. A logic analyzer also supports multiple triggering schemes to determine when data is acquired. The NI 655x has many features that make it ideal for digital waveform acquisitions. These include flexible memory sizes, voltage levels, and input impedances, advanced acquisition timing options, diverse acquisition triggering choices, powerful data visualization programming features, and extensive expansion and integration capabilities.
