LeCroy 9310AM Dual 400MHz Oscilloscope, 100MS/s

The LeCroy 9310AM is a dual-channel digital oscilloscope engineered for high-speed signal acquisition and waveform analysis. Operating at 400 MHz bandwidth with simultaneous 100 MS/s sampling across both channels, it captures up to 200k points per channel for detailed signal characterization. The instrument delivers 8-bit vertical resolution, ±2% DC accuracy, and flexible sensitivity from 2 mV/div to 5 V/div across dual independent digitizers.
