In preparation for some analog analysis of CARM and DARM, we set up and got some PSDs of REFL A 9 I (which is actually REFL A 9 Q at the racks due to our arbitrary delay).

Daniel helped us to used the patch panel in the CER to route analog DARM to the PSL racks.  

There hasn't been an obvious effect on DARM from our setup so far, so we will leave it like this for tonight.

Pictures are of the SR785 setup at the PSL racks,
the CER patch panel BNC we used a BNC to connect U2 patch 5 which goes to the PSL racks to U5 patch 6 which goes to the HAM6 racks,
our connection to the OMC DCPD Whitening Chassis (OMC DCPD A+ slot),
and our connection to the HAM6 patch panel.
