Lecroy LA303

The Teledyne LeCroy LA303 is a 200 MHz analog oscilloscope engineered for digital circuit debugging, signal validation, and real-time waveform analysis. This three-channel instrument (2 + 1) delivers 1 GS/s single-shot sampling and 500 MS/s repetitive sampling with a 10,000-point record length per channel, making it suitable for bench troubleshooting, design verification, and production test environments.
