Web links: Key points about Function Generators - Basics - Serving Applications

[Kiriakos GR]

Personally I got a true worthy function generator in May 2012,  as expansion regarding professional grade testing capabilities at ITTSB.

But the truth is that I have built my first basic frequency generator, due a electronics KIT, when I was just a kid in the age of 17 years old.
For audio and RF/FM band gear testing.

This link includes some good but very basic info, for understanding what is a function generator, what can it be used for, and how it works.

About my own analogue monster you can see some pictures here.
