LeCroy 332A Digital Oscilloscope 350MHz, 2 Channel

The LeCroy 332A is a 350 MHz, 2-channel digital oscilloscope engineered for signal analysis, debugging, and electronic testing. It delivers 2 GS/s interleaved or 1 GS/s all-channels real-time sampling, with equivalent time sampling to 100 GS/s and 500 kpts/channel waveform memory. Advanced triggering - edge, pulse width, period, pulse count, and TV types - supports auto, normal, single, and stop modes across any channel, external, or line sources.

The instrument captures glitches as small as 1 ns via peak detect and provides 26 automatic measurement parameters, FFT and waveform math functions, and a 6-digit frequency counter. Its 7.5" color VGA display renders waveforms, measurements, and menus without grid clutter. Dual USB ports enable front-panel peripherals and rear PC control; optional GPIB and Ethernet interfaces support remote operation via LeCroy ScopeExplorer and ActiveDSO utilities.

Replay mode archives up to 1,024 consecutive waveforms for anomaly isolation. Save waveforms in binary, ASCII, or Mathcad formats and screen images to USB media. Multi-language support includes English, Chinese, French, German, Italian, Japanese, Korean, Russian, and Spanish.

Compact at 190 mm H × 285 mm W × 102 mm D and 3.2 kg, with sub-3-second power-up. Each channel includes one PP006A passive probe.
