Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

If you have a modern function generator on your bench it is quite likely to contain a direct-digital synthesis circuit that creates arbitrary waveforms using a microprocessor controlled DAC. If you ...

When you buy the do-it-yourself kit, it requires a little solder work, and you will get everything needed to complete the project. The packet also includes a pretty good transparent acrylic enclosure, ...

Most of my Blog posts involve short 3-4 hour projects/hacks that I just build up for learning and fun. I thought it was time to develop something a bit more involved and share my design process in a ...

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables, and other ...

The Rigol oscilloscopes have a long history of modifications and hacks, and this latest from [Matthias] is an impressive addition; he’s been working on adding a function generator to the DHO800 line ...
