Digital Probe using a 12f675

This is a simple program to display digital signals on the PC. It can be used as a digital probe to analyze low frequency data.

RF Probe

allows RF to be measured in the presence of d.c.

Sniffer probe locates sources of EMI

this miniature special probe and an oscilloscope can help to locate and identify magnetic-field sources of EMI

Scope probe measures high frequencies

measuring clocks and critical signals accurately is often inconvenient and hard to do accurately with normal 10× probes, this article describes 100× probe that is easy to make and use, has a high bandwidth, and has a small (less than 1 pF) input capacitan

Modified oscilloscope probe tests surface-mount assemblies

small sizes and pad areas of surface-mount components make them difficult to probe but this simple tip helps it.
