LeCroy LC584AL Digital Oscilloscope, 1GHz, 2GS/s, 4 Channel

The LeCroy LC584AL is a 1 GHz digital oscilloscope built for high-speed signal capture and detailed waveform analysis across four channels. With a maximum single-channel sampling rate of 8 GS/s and multi-channel operation at 2 GS/s, it delivers accurate characterization of complex electronic signals. The instrument features 8-bit vertical resolution, variable sensitivity from 2 mV/div to 10 V/div, and up to 4 M words of record memory per channel.

Advanced triggering modes - including runt, slew rate, exclusion, qualified, and TV triggering - enable capture of intermittent faults and video signals. Time/div settings span 1 ns/div to 1000 s/div with Random Interleaved Sampling for repetitive signals and Sequence Mode for time-stamped event capture. The 9-inch color CRT display (640 × 480 pixels) and four zoom traces support efficient multi-parameter analysis.
