LeCroy WaveJet 312A Digital Oscilloscope 100MHz, 2 Channel

The LeCroy WaveJet 312A is a 100 MHz, 2-channel digital oscilloscope engineered for signal analysis, debugging, and transient event capture. Its 7.5-inch color TFT-LCD display (640 × 480 VGA) delivers clear waveform visualization in field and bench environments. The instrument combines flexible sampling architecture - 1 GS/s single-shot, 2 GS/s interleaved, or 100 GS/s RIS mode - with 500 kpts per-channel memory and 1 ns peak-detect resolution for fast transient isolation.

Vertical sensitivity spans 2 mV/div to 10 V/div across 8-bit resolution, with ±1.5% DC gain accuracy. Horizontal timebase ranges from 500 ps/div to 50 s/div, with 10 ppm typical accuracy. The oscilloscope supports multiple trigger types - edge, glitch, period, pulse count, and TV - and includes Replay Mode to review up to 1024 historical acquisitions for anomaly isolation.
