The LeCroy 44MXS-B is a 400 MHz, 4-channel digital oscilloscope engineered for high-performance signal acquisition and waveform analysis. It captures analog signals at up to 5 GS/s with 16 Mpts memory per channel, or 32 Mpts when operating two channels in interleaved mode. The 10.4-inch capacitive touchscreen display provides intuitive access to advanced measurement and processing tools, enabling engineers to analyze long memory records without performance degradation.

– Key Features
WaveStream™ Fast Viewing Mode delivers intensity-graded display (256 levels) with rapid update rates, exposing jitter and anomalous events typical of analog phosphor trace operation.
WaveScan™ isolates faults across analog and digital channels using over 20 search criteria. Scan extended periods for rare events or parallel bus pattern detection on multiple digital lines.
Sequence Mode captures up to 5,000 triggered events as timestamped segments with <1 μs dead-time between triggers—ideal for infrequent or time-separated signal acquisition.
Math Functions: 18 total, including FFT, averaging, derivative, envelope, enhanced resolution, integral, and standard arithmetic operations.
Measurement Parameters: 23 automated parameters including rise/fall time (10%-90%, 20%-80%), frequency, duty cycle, phase, skew, RMS, overshoot, and peak-peak amplitude.
LabNotebook streamlines documentation by saving waveforms, instrument settings, and screen captures for direct report generation.
