A differential probe, a device for measuring the voltage between two points in a circuit rather than the voltage between a point and ground, it an extremely useful addition to any electronics bench.

[Petteri Aimonen] presents for us a modular differential probe, as his entry into the 2021 Hackaday Prize. This project shows a simple and well polished implementation of a differential-to-single ...

Isolated differential probes are galvanically isolated and reject common-mode voltages, enabling power electronics engineers to measure floating circuits accurately and safely in high-voltage ...

Keysight Technologies recently unveiled an advanced family of optically isolated differential probes tailored for GaN and SiC semiconductors, gaining industry attention at the APEC 2025.
