Thanks for that great write-up of the AD9106 AWG boards. It's helped clarify a few things for me, thanks.
I have a couple of follow-up questions which I hope you can help me with...
Q1: you have an example of "SRAM factory waveform 0 AM modulation of 1MHz sine wave", which is a feature I'm interested in. Do you know if you can configure the device to do this continuously without pauses?
Q2: have you seen any references to "CH1_ADD" or "CH2_ADD" register bits in the interface? (They are part of the AD9106 register file but I don't know if the module supports them.)
