LeCroy 42Xs Digital Oscilloscope 400MHz, 2 Channel

The LeCroy 42Xs is a 400 MHz, 2-channel digital oscilloscope built for circuit testing, debugging, and signal analysis on the bench. Its 10.4-inch color touchscreen display and compact 152 mm depth make it equally suited to lab benches and tight spaces. The instrument captures signals at up to 5 GS/s per channel with 5 Mpts standard memory per channel, expandable to 25 Mpts interleaved, delivering the sample depth needed for complex transient capture and long-duration measurements.
