Teledyne LeCroy WaveRunner 9404 – 4GHz, 20 GS/s, 4 Channel Oscilloscope

The Teledyne LeCroy WaveRunner 9404 is a 4 GHz, 4-channel digital oscilloscope built for high-speed signal acquisition and analysis in laboratory and field environments. It combines 20 GS/s analog sampling with 16 digital channels at 1.25 GS/s, enabling simultaneous analog, digital, and serial protocol debugging on a single instrument. The MAUI with OneTouch interface leverages a 15.4″ capacitive touch screen for rapid setup and intuitive gesture-based control.
