Low-cost USB digitisers from National Instruments provide basic oscilloscope functionality for cost-sensitive applications. They are affordable enough for student use, yet powerful enough for more sophisticated measurement tasks, making them ideal for portable, bench top and OEM applications. The NI USB-5132/33 ships with a soft front panel and ready-to-run software - including NI LabVIEW SignalExpress LE, an interactive measurement workbench for taking and logging measurements with no programming, and the NI-SCOPE driver, for integrating with programming tools.
