After some work to optimize gain settings the FSS_FAST_GAIN has been set to 0.2 and FSS_COMMON_GAIN to 0.8. The gain slider on the MEDM screens is not accurate - a change of 0.1 dB on the slider is actually a change of 3 dB.
A new DBB measurement was created and is attached. A snapshot of the open loop transfer function and the error signal are attached as well.
