The LeCroy WaveRunner 640ZI is a 4-channel digital oscilloscope built for signal integrity analysis and high-speed circuit validation. It delivers 4 GHz bandwidth with 20 GS/s sampling across all four channels, capturing complex transient events with 16 Mpts per channel standard memory. The instrument combines precision analog measurement with advanced digital processing, making it suitable for engineers debugging high-speed designs, validating mixed-signal circuits, and performing detailed protocol and jitter analysis.
