LeCroy 334A Digital Oscilloscope 350MHz, 4 Channel

The LeCroy 334A is a four-channel, 350 MHz digital oscilloscope engineered for signal analysis, electronics testing, and complex waveform diagnostics. It delivers real-time capture and detailed characterization of fast transient events through a 2 GS/s single-channel sampling rate, 500 kpts/ch memory depth, and advanced triggering across all four inputs. The instrument combines a 7.5" color TFT-LCD display, 26 automatic measurements, FFT analysis, and multiple acquisition modes - including Peak Detect and Equivalent-Time Sampling up to 100 GS/s - to support both immediate troubleshooting and post-acquisition review of up to 1,024 consecutive waveforms.
