Subject: ITMX DAC noise 

I don't agree about this. Doesn;t this ignore the noise of the noisemon circuit (analog readout noise + ADC noise) ? I think you must have a model for than noise in order to infer the DAC noise. Or maybe my pringle suggestion has better SNR?

This is how we calculate the DAC noise spectrum. The unit is V/rtHz.

drive\times\sqrt{1-coherence}
