Measuring 230 VAC directly on a scope, without the right interface, is either dangerous or useless. That’s what this probe is for.
It provides full galvanic isolation between the measurement side and the oscilloscope input — which is usually earth-referenced. It preserves enough signal fidelity for meaningful waveform analysis while staying robust enough for repeated bench use.
Everything is packaged inside a dedicated enclosure, making it a real lab instrument rather than a bare circuit on a desk. It’s the kind of tool you build once and use on every project involving mains: switching power supplies, protection circuits, sensing stages, anything that has to survive and behave correctly at 230 VAC. Worth every hour spent building it.
