I'm using a 2206B scope and I'm very pleased with it!
I would prefer the AWG interface to be available as a toolbar option along top or side rather than a dialog covering part of the waveform display area.
That's because I typically make lots of adjustments to the AWG output while observing the same A B input channels (e.g. switching from sine to square to white noise to sweep etc. to evaluate responses).
I can't find any way to change the dialog to a toolbar so I'm guessing the option doesn't exist at present.
Best regards
Ian
