The LeCroy 9314CL is a four-channel digital oscilloscope from the 9300C series delivering 400 MHz bandwidth with 100 MS/s simultaneous sampling across all channels. Built on a 22.86 cm CRT monochrome display, this instrument combines high-speed acquisition with flexible memory configurations to support demanding measurement tasks in digital circuit validation, signal integrity analysis, and embedded systems development.

– Key Features
• Four independent digitizers enable true simultaneous multi-channel capture
• Configurable memory depth balances acquisition length against sample rate requirements
• Flexible triggering with window mode and event-based holdoff for complex signal protocols
• DC to 400 MHz bandwidth supports both low-speed control signals and high-frequency digital edges
• Persistent display modes reveal intermittent or low-probability events
– Typical Applications
• Digital logic and timing analysis
• Power supply transient characterization
• Signal integrity verification in embedded designs
• Protocol-level trigger and decode workflows with external interfaces
– Compatibility & Integration
USB and LAN connectivity enable remote operation and data transfer. GPIB is available as an optional interface for legacy test automation environments. Input impedance options (1 MΩ || 14 pF or 50 Ω) accommodate both high-impedance probed circuits and RF/transmission-line measurements.
