LeCroy 44MXS-A Digital Oscilloscope 400MHz, 4 Channel

The LeCroy 44MXS-A is a 4-channel digital oscilloscope delivering 400 MHz bandwidth and 2.5 GS/s sample rate per channel for efficient signal debugging and analysis. The instrument features a 10.4-inch color touch screen, 10 Mpts/channel standard memory, and 875 ps rise time with 8-bit vertical resolution. Its flexible input architecture supports both 1 MΩ and 50 Ω impedance paths, with vertical sensitivity from 2 mV/div to 10 V/div on high impedance or 1 V/div on 50 Ω inputs.

Vertical DC gain accuracy reaches ±1.0% of full scale.
