LeCroy SDA806ZI-B Oscilloscope, 6 GHz, 40 GS/s, 4 Channel

The LeCroy SDA806ZI-B is a 6 GHz benchtop oscilloscope purpose-built for serial data analysis and compliance testing. It delivers 40 GS/s sampling across four analog channels, with 64 Mpts/channel standard memory and expansion to 256 Mpts/channel. The instrument combines high-speed acquisition with integrated serial protocol triggering and advanced jitter analysis, making it suitable for characterizing high-speed digital signals and multi-lane serial interfaces.
