LeCroy SDA-725Zi Digital Oscilloscope, 100GHz, 4 Channel, 1MSa/sec

The Teledyne LeCroy WavePro 725Zi is a 4-channel benchtop digital oscilloscope built on the X-Stream II architecture for high-speed data acquisition and analysis. It delivers 2.5 GHz analog bandwidth at 50 Ω input with a 150 ps typical rise time, 40 GS/s maximum sample rate, and up to 256 Mpts of acquisition memory. The instrument features a 15.3" widescreen color touchscreen display and supports multiple input impedance options: 50 Ω, 1 MΩ, and 10 MΩ with supplied probe.
