SR Prep Tasks - To Be Scheduled
Tunnel
- Retrieve BNC-Lemo cable from Nakano-kun.

- Install, cable SR3 PI yaw stepper.
- Correct flipped connections in SR2 PI LVDTs.
- Correct flipped connections in SRM PI LVDTs.
- Grab and configure a picomotor driver as SR2_BF 10.68.150.25.
- Get independent power supply for SR3 so SR2 can be powered back up.
- Check SR2, SR3 TM coil gains for magnet polarity compensation.
- Calibrate last six IM OSEMs.
- Rebuild filter in PI #1.
- Install clamps on PI #1.
- Install geophone plates on PI #3.
- Install geophone plates on PI #1.
- Install correct IP in PI #2.
- Rebuild filter in PI #2.

- Install LBB blade units on PI #2.
- Install geophone plates on PI #2.
- Replace chipped magnets (12x12x12 mm) in SR3 IP, H1 and H2.
Mitaka or remotely
- Write generic Type B Guardian; make BS and SR3 inherit from it; make analog WD optional for now (all suspensions will get them eventually).
- Create software stepper drivers for SR3 and SRM and link to them from STEP_MASTER.adl screen.
- Make three in-air stepper splitter cables for SR2, SR3 and SRM. [done?]
- (Continue to) soak the sapphire prisms off the dummy BS for reuse on the SRM metal mass.
- Set up SR2 Guardian.
- Install damping filters for SR2.
- Review DAC channel requests.
- Set up SR2 Guardian.
- Install damping filters for SR2.
- Split SRx real-time models?
