LeCroy 104Xs WaveSurfer Digital Oscilloscope 1 GHz, 4 Channel

The LeCroy 104Xs WaveSurfer is a 1 GHz, 4-channel digital oscilloscope engineered for signal integrity testing, debugging, and design verification. Its 10.4-inch color touch-screen display and compact 6-inch depth integrate into lab and field environments. The instrument delivers 2.5 GS/s single-shot sampling, scaling to 5 GS/s interleaved and 50 GS/s in RIS mode, with standard 5 Mpts/channel record length and optional 10 Mpts/channel memory expansion. Advanced triggering modes—edge, glitch, width, logic pattern, and TV—isolate specific events with 1 ns sensitivity (500 ps for width and glitch). Vertical resolution reaches 8-bits across four channels with sensitivities from 2 mV/div to 10 V/div (1 MΩ input) or 2 mV/div to 1 V/div (50 Ω input). Bandwidth limiting filters at 20 MHz and 200 MHz reduce noise. Time-base accuracy of ≤5 ppm @ 25 °C enables precise horizontal measurements from 200 ps/div to 1000 s/div. Capture windows extend to 1 ms at full sample rate on all four channels, 2 ms on the 104Xs-A variant, or 400 ms with standard memory. The oscilloscope provides up to six simultaneous parameter measurements including amplitude, frequency, rise/fall times, duty cycle, and phase. Standard math functions include sum, difference, product, ratio, and FFT (up to 25 kpts) with power spectrum output and multiple windows. Optional Extended Math Software Package adds absolute value, averaging, derivative, envelope, enhanced resolution to 11-bits, integral, and function chaining. Vertical gain accuracy is ±1.0% of full scale typical, ±1.5% of full scale warranted at ≥10 mV/div.
