The LeCroy MS-250 is a mixed-signal acquisition module that expands compatible Teledyne LeCroy oscilloscopes with 18 digital channels and advanced triggering capabilities. It enables simultaneous capture and analysis of analog, digital, and serial signals in embedded systems and microcontroller designs. The module connects via USB 2.0 and LeCroy Bus Cable to WaveRunner MXi and WaveSurfer MXs series oscilloscopes, providing a unified platform for real-time signal debugging and protocol analysis.
Technical Specifications
• Bandwidth: 250 MHz
• Digital Channels: 18 (D0–D17)

• Weight: 775 g
– Key Features
• Configurable logic thresholds supporting TTL, ECL, CMOS (2.5 V, 3.3 V, 5 V), PECL, and LVDS families with user-defined options
• Per-bank hysteresis configuration for threshold customization
• Digital group management enabling bus creation and hexadecimal value reading via cursors
• Edge, Width, Pattern, Glitch, Interval, and Dropout triggering modes
• Automatic measurements including period, frequency, and duty cycle on digital lines
• Statistics and histicon support for detailed signal characterization
• Digital signals displayable as single-line or collapsed bus traces with standard oscilloscope analysis tools
– Typical Applications
Ideal for 8-bit microcontroller systems and slower digital signal analysis. Supports embedded system debugging, digital protocol capture, and mixed-signal correlation where simultaneous analog and digital acquisition accelerates problem identification.
– Compatibility & Integration
Requires Teledyne LeCroy WaveRunner MXi or WaveSurfer MXs series host oscilloscope. Analog channel count and sampling rates depend on host oscilloscope configuration (up to 4 analog channels and 10 GS/s on MXi/MXs platforms).
