WaveScope 4C Pro is a professional 4-channel automotive oscilloscope engineered for modern vehicles. With 100 MHz bandwidth, 1 GSa/s real-time sampling, and 50 Mpts memory depth, it captures fast transients, high-resolution crank/cam correlation, injector current ramps, CAN/LIN/FlexRay frames, and charging system ripple with lab-grade accuracy. Pair it with our Android app for guided tests and mobile portability in the bay or on the road.
Why technicians choose WaveScope 4C Pro
- 4 isolated BNC channels for multi-sensor correlation (crank, cam, primary/secondary ignition, injector, fuel pump, MAF/MAP, throttle, O2/AFR, ABS).
- Fast acquisition: up to 1 GSa/s sampling, ≤ 3.5 ns rise time, and deep 50 Mpts capture for long recordings without decimation.
- Automotive-ready triggers: Edge & Pulse with Automatic/Normal/Single modes for intermittent faults and glitch hunting.
- Built-in auto measurements: frequency, period, duty cycle (positive/negative), pulse widths, rise/fall time, phase, peak-to-peak, RMS, min/max/avg, cycle RMS/mean.
- Guided test library for Circuits, Sensors, Actuators, Ignition, Networks, and Combination tests—ideal for repeatable diagnostics and training.
- Mobile workflow: Android application (Android 7.0+) with Type-C connectivity for ultimate portability in the field.
- Rugged enclosure with cable support, calibration square-wave output, and compact footprint for cart or passenger seat use.
Typical Automotive Use Cases
- Engine management: crankshaft/camshaft sync, VVT control, ignition primary/secondary, injector voltage & current ramp, coil-on-plug (COP) analysis.
- Charging/starting: starter current, 12 V/24 V cranking voltage drop, alternator ripple, diode faults.
- Actuators: PWM fans, EGR/Evap solenoids, electronic throttle control, fuel pump command/feedback.
- Sensors: MAF/MAP, TPS, Hall/inductive, knock, oxygen/AFR, wheel speed/ABS, pressure and temperature transducers.
- Networks: CAN Low/High, CAN FD, LIN, FlexRay, K-Line—frame integrity, wake-up, line bias, and noise checks.
- Combination tests: multi-channel correlation (e.g., crank + cam + injector + ignition) to pinpoint timing or synchronization faults.

Designed for Professional Diagnostics
- High-resolution captures with deep memory for long crank/no-start recordings without losing timing detail.
- Noise-robust inputs with proper 1 MΩ/14 pF impedance for accurate sensor signal loading.
- Single-shot triggering to catch one-time misfires, dropout events, network wake-ups, and injector anomalies.
- Comprehensive guided library to standardize test hookup, scaling, and waveform interpretation.
What you can diagnose with WaveScope 4C Pro
Misfires, no-starts, cam/crank sync errors, stretched timing chains, weak coils, saturated injectors, shorted solenoids, alternator diode ripple, PWM control issues, network wiring faults (short-to-ground/short-to-VBAT), and intermittent harness/connectivity problems.
Included Calibration & Safety
- Front-panel calibration square-wave source for probe compensation and channel verification.
- Guided notes for safe connection using piercing probes and alligator clips.
What this scope replaces
4-channel handheld lab scope, DSO for automotive, CAN bus oscilloscope, ignition scope, injector current probe scope, engine analyzer, and network analyzer for CAN/LIN/FlexRay diagnostics.
