The LeCroy WaveRunner LT344 is a 500 MHz, 4-channel digital oscilloscope engineered for signal analysis, waveform capture, and debugging in laboratory and field environments. It delivers 500 MS/s single-shot sampling, up to 25 GS/s repetitive sampling, and 250 kpts/channel acquisition memory. The instrument combines flexible triggering—including edge, pulse width, and glitch detection down to 2 ns—with dual impedance inputs (50 Ω and 1 MΩ), adjustable bandwidth limiting (25 MHz or 200 MHz per channel), and analog persistence to accelerate fault isolation and signal characterization.
