The LeCroy WaveMaster 8420A is a 4-channel digital oscilloscope engineered for demanding digital and communications applications requiring high bandwidth and fast acquisition. Operating at 4.0 GHz bandwidth with 20 GSa/s sampling across all channels, it delivers the speed and memory depth needed for complex signal analysis. X-Stream technology accelerates data transfer and processing by 10–100 times compared to conventional oscilloscopes, enabling rapid WaveShape Analysis and reducing test cycle times.
