Oscilloscope probes are handy tools for making measurements, but they have limitations. For example, they have rather limited bandwidth and that ground clip can create a loop that can pick up noise.

Consider measuring a signal from a 75 Ω source like a video camera. The camera is designed to work into a 75 Ω load. In order to ensure a proper impedance match between the source and the oscilloscope ...

Texas instruments has revealed a buffer amplifier developed especially for oscilloscope inputs from dc to GHz. Texas instruments has revealed a buffer amplifier developed especially for oscilloscope ...

Probing is critical to making quality oscilloscope measurements, and often the probe is the first link in the oscilloscope measurement chain. If probe performance is not adequate for your application, ...

The oscilloscope is probably the most versatile piece of test equipment you can have on your electronics bench, offering a multitude of possibilities for measuring timing, frequency and voltage as ...

[jgpeiro] is no slouch when it comes to building small, affordable oscilloscopes out of common microcontrollers. His most recent, based on an RP2040 with two channels that ran at 100 MSps, put it on ...
