The 1200X is a compact 2-channel scope well-suited for education and basic bench work. The 4000X is a professional-grade instrument with a 12.1-inch capacitive touch display — the largest in the InfiniiVision lineup — and InfiniiScan automated anomaly detection. The 4000X delivers 20× the waveform update rate (1M vs 50k wfms/s), 4 channels, and up to 1.5 GHz bandwidth. The two scopes are designed for different user profiles: the 1200X for budget-conscious and educational use, the 4000X for design validation and multi-channel professional measurement.
