Dedicated differential probes are carefully designed with matched inputs, shielding, and circuitry that reject common-mode noise and interference. In contrast, the A–B math method relies on two ...

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.

With digital scopes that offer 6-GHz bandwidth suddenly almost commonplace and with industry participants now recognizing differential signaling as all but essential for sending multigigahertz signals ...
