The LeCroy 9354AM is a four-channel digital oscilloscope delivering 500 MHz bandwidth with independent digitizers per channel and sampling rates up to 2 GS/s across combined channels. Built for signal acquisition in design, test, and research environments, it combines high-speed sampling with deep memory and sophisticated triggering to capture fast transients and complex waveforms without data loss.
