Using SCPI commands, I was able to play around with the features of the DS2000-S waveform generator 'inside' of the new firmware on the DS2000: setting the frequencies, voltage levels, phase, etc. of the two source channels. I also located (but haven't tested yet) the command to download waveforms to the AWG.
Of course, without any external outputs on my model (and not having it open), it was impossible to know if anything other than variable settings inside memory were being affected (probably not of course). I haven't been able to make the DSO show anything (including the new menus or screen icons associated with the AWG - as shown in the image), so I'm wondering if those things are tied to having the model number with the "-S" in non-volatile memory (just like the bandwidth, 2ns timebase, and 100MHz filter seem to be tied to the model number inside the DS2XXX).
