Why compare a commercially available top of the line function generator with a hobby project?
Because as soon as you do, you start to realize that you can get quite a ways with commodity hardware. Hence, why I started this project. The research I've done on the frontend of this on what's available in the market suggests to me that there's a niche for something that's a little cheaper, and a little easier to use. I also have a hunch that portability is a nice feature for most folks as well.
(Hi Jacques!)
- jacquesm 7y agoThere is a whole branch of Chinese manufactured pc peripherals aimed squarely at this space, digital scopes, spectrum analyzers and so on, don't they make a function generator?
- cushychicken 7y agoThey do, but the usability leaves something to be desired.
- aDfbrtVt 7y agoPlease don't take the comments I wrote above as overt criticism, I was trying to point out some of the potential pitfalls in DIY function generators. As I said your project seems really interesting, especially if the software interface is polished.
- cushychicken 7y agoNot at all! They're all things I'm learning myself. Some were lessons I knew I was going to have to learn, but there have been a few I didn't really expect to learn about. That HP manual was a great link. I've been studying it over the last few days. Thanks for sending it. :) The only one I'm really kicking myself over is not including an antialiasing filter at the DAC output. Seems like a bushleague mistake considering I paid all that money to get this EE degree.
- aDfbrtVt 7y agoI can definitely sympathize, but anytime you take on a new project like this for the first time you're bound to at least make some stupid mistakes. I'll be following the project closely, hopefully you manage to overcome all the difficulties!
