  1. Configure the main registers of the SMURF board (to be detailed)
  2. Set the bias of the cryogenic amplifiers. The bias are provided by the manufacturer. 
  3. Find the resonator frequencies - 
    1. Each multiplexed line must be scanned in frequency. The resonators are situated where the amplitude of the signal drops and there is a phase discontinuity. The phase discontinuity is used to determine the most precise frequency of the resonators. If 2 resonators are too close, one needs to be turned off to avoid crosstalk.
  4. SetupNotches - Find the transformation η(I,Q) = (I', Q') where η is a complex tranformationtransformation. We want to move the operation point so that we are at the (I', Q') = (1,0) point and that all variations maximized their projection on Q'. Image Added
  5. Setup the flux ramp  
    1. Flux amplitude
    2. Ramp amplitude
