In short, [Christer] needed a high-frequency active differential oscilloscope probe, and they’re not cheap. So he built one himself. With some minor tweaking on the input damping resistors ...

This requirement is particularly acute in the power electronics industry, where the increase in applications for and production of next-generation power devices utilising SiC technology necessitates ...

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.

Saelig Company, Inc. has introduced the Sensepeek SQG-series of passive high-frequency hands-free oscilloscope probes, designed for both AC and DC GHz applications.
