The LeCroy 9361 is a dual-channel, 300 MHz digital oscilloscope engineered for precise signal capture and analysis of single-shot events. Operating at 2.5 GSa/s simultaneous sampling per channel with a 25,000-point record length, the instrument delivers 1.16 ns rise time and 1 ns minimum glitch trigger capability. Its 9-inch CRT display renders waveforms at 810 × 696 pixel resolution, while SMART Trigger modes—Glitch, Window, and Dropout—enable deterministic event capture. The 9361 accepts input from 2 mV/div to 5 V/div, supports dual input impedance configurations (1 MΩ || 15 pF or 50 Ω ± 1%), and handles up to ±250 V (1 MΩ input) or ±5 V (50 Ω input). Timebase ranges span 1 ns/div to 1000 s/div with ±0.07% accuracy. Pre-trigger recording adjusts from 0 to 100% of full scale in 1% increments; post-trigger delay extends to 10,000 divisions. Trigger sources include CH1, CH2, Line, External, and External/10, with sensitivity as low as 0.1 mV and bandwidth up to 500 MHz. Advanced waveform processing performs signal manipulation without corrupting source data. Display modes include Normal, Persistence, and X/Y; persistence options support Normal and Infinite modes. Zoom functions reach 200× horizontal and 5× vertical expansion. Data archival uses floppy disk and PCMCIA card media, enabling transfer of waveforms, screen graphics, and test configurations to external systems.
