The LeCroy LC534AL is a 500 MHz color digital oscilloscope engineered for signal analysis, troubleshooting, and event capture across extended time intervals. Its 9-inch color CRT display combines analog persistence, color-graded persistence, and customizable color schemes to reveal signal behavior and transient phenomena with high resolution. The instrument acquires 8 million points at 2 GS/s in single-shot mode, supporting time-base settings from 10 ns/div to 1,000 s/div through multiple acquisition modes including Random Interleaved Sampling (RIS), Peak Detect, Sequence, and Roll mode.
