The LeCroy WavePro 740Zi is a 4-channel digital oscilloscope delivering 4 GHz bandwidth and 20 GSa/s sampling across all channels, with capability to reach 40 GSa/s in interleaved mode. Built on the X-Stream II architecture, it combines deep memory acquisition (up to 10 Mpts/channel standard, expandable to 256 Mpts/channel with optional upgrades) with fast processing for signal analysis, debugging, and compliance validation in complex electronic designs.
