cool, I'd be interested to see the rise time of the function generator on a square wave. Most modern ones aren't great that I've seen (compared to say a beta22 specifications), and it would be nice to have another alternative. I can very much recommend the Tek CFG280, that's what I have and it's very solid unit. It has the advantage of being able to apply a DC offset to the waveform, which means you can do things like bias devices. It's a very handy feature in fact. It does other cool things as well, but this is my favorite feature so far.
