LeCroy LT344 Waverunner Digital Storage Oscilloscope, 500MHz, 500MS/s, 4 Channel

The LeCroy LT344 Waverunner is a 4-channel digital storage oscilloscope delivering 500 MHz bandwidth and 500 MS/s sample rate for high-frequency signal acquisition and analysis. The instrument captures up to 250 kpts per channel with 16-bit vertical resolution, enabling detailed waveform characterization across DC to 500 MHz signals. An 8.4-inch color TFT-LCD display (640 × 480 VGA resolution) presents waveforms, measurements, and analysis results with Analog Persistence visualization and color-graded persistence modes.
