MS-500

The Teledyne LeCroy MS-500 is a high-performance Mixed Signal Oscilloscope (MSO) module that adds 36 digital channels to compatible LeCroy oscilloscopes, including the WaveRunner Xi and WaveSurfer Xs series. Designed to capture long records of fast digital signals, it offers a maximum input frequency of 500 MHz, up to 2 GS/s sampling, and a deep memory of up to 50 Mpts/Ch. This module enables embedded system designers to view and analyze analog, digital, and serial data signals simultaneously with precise time correlation.
