After [Frank] made a simple signal generator with a few parts he had lying around, he needed a probe. Not wanting to deal with poking loose wires around his circuits, he decided to modify a scope ...

In a pair of columns recently, Probing pointers and Probing Pointers: Take 2, I discussed some of the issues that arise in using scope probes as frequencies increase. Alas, too few engineers do a real ...

This uses the mains signal powering the scope to trigger the measurements which is quite handy for this particular exercise. But when I went to probe the rectified waveform I was met with a surprise.
