The LeCroy WaveRunner series of digital oscilloscopes offer powerful tools at reasonable prices. WaveRunner oscilloscopes feature a user interface that is simple to learn and use, making it easy to take advantage of the scope's unique capabilities. SMART Trigger and SMART Memory let you capture signals while maintaining the maximum resolution and accuracy. The large, crisp 8.4" TFT flat display with analog and color-graded persistence makes it easy to view and measure signals, as well as locate rare signal problems. All models include automatic measurements, waveform math functions, and analysis capabilities so you can average sweeps, enhance vertical resolution, and use FFT to view a signal's frequency spectrum.
