The LeCroy 222 Wave Ace is a 2-channel digital oscilloscope delivering 200 MHz bandwidth and 2 GS/s maximum sample rate for signal acquisition and analysis across electronic testing and measurement applications. With 1.75 ns rise time and peak detect capability at 2.5 ns, it captures fast transients and subtle signal details. The instrument provides 9 kpts per channel waveform memory, expandable to 18 kpts interleaved, plus a 50 GS/s RIS sample rate for enhanced time-domain resolution.
Edge, pulse width, video, and slope triggering modes enable precise event detection. A 5.7-inch color display (320 x 240 resolution) presents real-time waveforms with intuitive control. The vertical axis spans 2 mV/div to 5 V/div across 8-bit resolution, while the timebase ranges from 2.5 ns/div to 50 s/div. A 20 MHz bandwidth limiting filter reduces noise when needed.
Analysis capabilities include 32 automatic measurements covering rise time, fall time, frequency, duty cycle, RMS, peak-peak voltage, and phase. Four math functions—Add, Subtract, Multiply, Divide—plus FFT (up to 1 kpts with selectable windows) support advanced signal processing. The waveform sequence recorder captures up to 2500 frames for trend analysis. Pass/Fail testing and value averaging (up to 256 runs) accelerate production validation.
