The Teledyne LeCroy WaveRunner 9404M-MS is a 4-channel mixed-signal oscilloscope built for complex signal analysis in design validation and debugging workflows. It delivers 4 GHz analog bandwidth with 40 GS/s sampling across four analog channels, paired with 16 digital channels operating at 1.25 GS/s. The combination provides unified analog-digital visibility in a single instrument, eliminating the need for separate test equipment.
The 15.4-inch WXGA capacitive touchscreen runs MAUI with OneTouch interface, enabling gesture control and drag-and-drop cursor management, source selection, and measurement adjustments. Memory depth reaches 128 Mpts per channel on standard M models.

– Key Features
Signal analysis leverages 50+ waveform tools with spectral capability. Math tracing supports up to 8 functions (F1–F8) with chaining, including averaging, difference, product, ratio, reciprocal, and sum operations. FFT analysis offers power spectrum, magnitude, phase, power density, real, imaginary, and magnitude-squared modes across five window types: Rectangular, VonHann, Hamming, FlatTop, and Blackman Harris. Vertical resolution extends to 11 bits with cubic, quadratic, and sinx/x interpolation.
Triggering options span edge, runts, edge rates (dV/dt slope), intervals, dropout, and measurement parameter types. Cascade triggering allows conditional triggering across inputs with selectable delay.
Serial data analysis covers up to 29 standards with decoders, jitter decomposition (Tj, Rj, Dj), eye diagrams, and compliance packages. Automotive protocol support includes CAN, CAN FD, LIN, FlexRay, SENT, and MOST with dedicated measure, graph, and eye diagram packages.
– Connectivity & Integration
External display connections: HDMI 1.4 (1 port) and DisplayPort 1.2 (1 port).
