The LeCroy LC574AM is a 1 GHz, four-channel digital oscilloscope engineered for high-resolution signal capture and detailed waveform analysis. It delivers up to 4 GS/s sampling rate in single-channel mode and 8 million points of total acquisition memory, enabling engineers to resolve fast transients and capture extended signal sequences. The instrument combines flexible triggering—including Glitch, Runt, Slew-Rate, and Width modes with 600 ps glitch detection—with dual input impedance options (10 MΩ or 50 Ω) and vertical sensitivity ranging from 2 mV/div to 10 V/div, making it suitable for mixed-signal debug, high-speed design verification, and complex waveform characterization across analog and digital domains.
