I take a detailed look at a cheap $100 function generator that came out recently, from JunCe Instruments.
Measuring amplitudes, checking harmonic distortion, making some funky waveforms, and seeing what's inside!
Looking at the 25MHz model in this review.
There are a few things I'd still like to test (PC connectivity and measurement capability for example)
I have posted some high-resolution images of the teardown over at the EEVBLOG forum here: https://www.eevblog.com/forum/testgear/anybody-know-anything-about-this-signal-generator/
(As well as some additional tests)
Repeated here for convenience:
