Frequency! It’s an important thing to measure, which is why [Jacques Pelletier] built a frequency counter some time ago. The four-function unit is humble, capable, and also an entry into our 2025 One ...

The great thing about building with gates is the crazy speeds you can achieve by using hardware directly (as opposed to working with simple microcontrollers). This 100 MHz frequency counter is a great ...

The project aims to build a simple and easily-reproducible RF/Microwave frequency counter that is based around a PIC16F876A microcontroller. This particular frequency counter has three inputs ...

The Model 1856C frequency counter is capable of measuring from 5 Hz to 2.4 GHz and features a special 50½-terminated input for use in with VHF, UHF, microwave, and cellular telephone systems. A ...

I was recently working on an experiment for a new design and was using a function generator. Although new function generators have pretty good frequency tolerance specs, I needed something with more ...
