The LeCroy LC684DM is a 1.5 GHz digital oscilloscope built for high-speed signal capture and analysis. Four channels operating at 8 GS/s deliver precision waveform acquisition across transient events and complex signal integrity investigations. With trigger jitter below 1 ps RMS, comprehensive triggering modes including edge, pulse width, logic, pattern, and video detection, and an 8-bit vertical resolution, this instrument supports demanding verification and development workflows.
