The LeCroy LA354 is a 4-channel analog oscilloscope delivering 500 MHz bandwidth across all channels for detailed signal analysis and waveform characterization. Built around a 2-inch scan converter tube with CCD imaging (approximately 450 × 700 pixels), this instrument excels at capturing infrequent and irregular signals using variable persistence display technology—a critical advantage for glitch detection, single-event analysis, and video signal examination. The 5.5-inch color TFT-LCD with electronic 8 × 10 division graticule provides real-time waveform visualization with persistence, enabling engineers to observe noise, jitter, and transient behavior that can escape traditional digital oscilloscopes.
