LeCroy WaveJet 312 Digital Oscilloscope 100MHz, 2 Channel

The LeCroy WaveJet 312 is a 100 MHz, 2-channel digital oscilloscope engineered for circuit testing, design verification, and signal debugging. It delivers 1 GS/s real-time sampling with equivalent-time capability up to 100 GS/s, 500 kpts memory depth per channel, and 8-bit vertical resolution across a 2 mV/div to 10 V/div sensitivity range. The instrument combines portable form factor with benchtop performance, offering 26 automatic measurements, advanced triggering modes including edge, pulse width, period, and TV triggers, plus waveform math and FFT analysis.

A 7.5" color TFT display (640 × 480 VGA) provides clear signal visualization. Peak Detect mode captures transients as narrow as 1 ns. Timebase spans 5 ns/div to 50 s/div with 50 ppm accuracy.

Multiple acquisition modes

Peak Detect, Equivalent-time Sampling, Roll Mode, and averaging up to 256 runs - adapt to diverse measurement scenarios. Input coupling options include GND, DC 1 MΩ, AC 1 MΩ, and DC 50 Ω with 400 V CAT I maximum input rating. The BNC probe interface features Probe Sense Ring technology for automatic probe attenuation detection.

Includes one PP010 probe per channel. Vertical DC gain accuracy is ±(1.5% + 0.5% of full scale). A 6-digit frequency counter displays continuously.
