SR3 transfer functions, cleared for doors

I took the SR3 transfer functions this afternoon. I took SUS_SR3 to damped then reengaged the test filter outputs and set gains to 1, and turned off the damping filter outputs and set the M1 coil driver state from 2 to 1.

While taking the V TF Rahul and I noticed the shapes looked weird, from this we noticed that the T1 analog dewhitening coil driver wasn't switching on and off which led to the investigations in alog79419.
