Roopal Bansal : It is very well explained! Thanks a lot :)
James Lacy Kamuf : I have a very fundamental understanding of RF (even though I got a B.S. in E.E,. more than 20 years ago); that said, I thought this was an excellent presentation in order to help me understand the basic difference between analog, and vector signal generators; keep up the great work.
Sudeep Shetty : Thanks for the presentation on signal generator.
Sudeep Shetty : How signal generators are protected from high return power cases ? Is there any tips to identify the signal generator conditions(safe operation or critical) during run time?
Dunamis Crisostomo : What is/are the resources of this presentation? Can i have it?

In this episode of DIY or Buy we will have a short look at commercial function/waveform generators in order to determine what features are important for a DIY version. Afterwards I will then show you how to create a simple function generator, the analog and digital way. At the end I will then present you a DIY DDS function generator design which can (kind of) hold up to the commercial versions. Let's get started!

Zonia : I've been wanting to build my own function generator for a while now. Thanks for posting this.
Settwi : I really like your content, and I appreciate how clear you are with your whole process, especially the analysis of data sheets and circuit diagramming. Thank you!
Alen Asenie : -"it did't result in an explosion, perfect"

Electroboom disaproves
Bill Kerr : Awesome! This goes on my (already long) project list.
Krystian Waga : nice project ,you could use AD9851 or AD9850 for higher frequency ,btw it should be possible to modulate signal eg. AM or FM ,it may be useful

Instrument Basics: Function Generator - Workbench Wednesdays

Generating signals with a waveform, function, or arbitrary generator lets you test all kinds of circuits. Learn how to get a function generator to output a signal, the 3 types of waveforms you can create, and which controls matter. James, the Bald Engineer, explains the difference between analog and digital generators:

Roadtest and Reviews:
Rudy : I haven't used a function generator but I have seen the sweep function used when testing audio amplifier circuits. 20hz to 20khz sine wave, to see if amplification is close to linear throughout the range.
AMERICANREBEL ! : Thank you for the info, I'm 57 and just now learning, ultimately I want to repair flat screen TV. Thank you Element 14!
Ramiro Suarez : I loved the explanation, and the reference to the graphing calculators.
Gerasimos Melissaratos : I'll suggest this video to the students. They will learn something and enjoy your presentation.
john swilley : Succinct and informative, I liked your presentation so much that I subscribed. Best wishes!
