The LeCroy LC684DL is a 1.5 GHz digital oscilloscope built for signal acquisition, waveform characterization, and complex electronic testing. Its four channels deliver 8 GS/s sampling rate with up to 24 million points per channel, enabling detailed capture of fast transients and intricate signal behavior. The instrument combines flexible triggering modes—including edge, pulse width, logic, video, pattern, runt, glitch, and setup/hold triggers—with over 100 automatic measurements and advanced math functions including FFT analysis. Selectable vertical resolution (8-bit or 10-bit enhanced), bandwidth limiters (20 MHz to full 1.5 GHz), and noise reduction features support both general-purpose and specialized measurement tasks across multiple channels simultaneously.
