The LeCroy WaveRunner 44Xi-A is a 400 MHz, 4-channel digital oscilloscope engineered for signal analysis, debugging, and multi-domain waveform capture. Operating at 5 GSa/sec with 12.5 Mpts/channel memory depth, it delivers the acquisition speed and storage capacity required for complex transient characterization. The instrument supports advanced triggering—including edge, pulse width, runt, timeout, window, logic, setup/hold, rise/fall time, pattern, state, delay, and video triggers, plus SMART Triggers and serial protocol pattern recognition across I2C, SPI, UART, RS-232, LIN, CAN, and FlexRay. An 8-bit vertical resolution and <875 ps rise time ensure signal fidelity across a 1 mV/div to 10 V/div input range, with ±400 V (DC + AC peak) overvoltage protection.
