function generator build one or buy one

Hi Dave,

I think it is time to introduce us your lab function, and show us the extent of difference between when using a cheapy one and an expensive when testing a circuit or product

If you just need a sine wave generator, how about this DDS kit?

About $50 for a kit that can do 60Mhz.  You still have to
interface it to a micro of some sort.

With a high speed comparator, you could also generate square
waves pretty easily.  You can use one of the circuits here:
