From the project
Modular differential probe (DEDP-100)
Modular differential probe (DEDP-100) =====================================
This repository contains the design files of a 100 MHz differential probe for use with oscilloscopes. The design is modular and consists of a base amplifier unit with exchangeable probe tip accessories. The accessory can be chosen to fit the desired voltage range and connection type.
Currently this project is still in development. While the prototype revisions work well, they are still being redesigned for improvements.
