The LeCroy SDA-816Zi-A is a 16 GHz realtime serial data analyzer built on the WaveMaster 8 Zi Series platform, engineered for high-speed digital interface characterization and debugging. It delivers 40 GS/s single-shot sampling across 4 channels with expandable memory up to 256 Mpts/channel, enabling capture of complex transient events and long data sequences. The instrument combines true hardware serial pattern triggering at 6.5 Gb/s (upgradeable to 14.1 Gb/s), 80-bit NRZ pattern recognition, and 8b/10b symbol-level triggering to isolate protocol violations and rare events. Deep segmentation—up to 15,000 segments with 1 µs intersegment time—supports efficient acquisition of intermittent faults. Advanced features include four-stage Cascade triggering, TriggerScan automated pattern search, and 10 SMART trigger types for comprehensive protocol analysis across PCIe, LVDS, USB, SAS, and proprietary serial buses.
