Tested and Installed New CNS II GPS Clocks in EX and EY
Filiberto, Jim, Dave

Installed one new CNS Clock II in each end station in receiving, directly above the Timing IRIG-B Module in each rack. We tested each unit to make sure it successfully locks to a GPS signal.

Filiberto ran an extension cable for the GPS antenna from VEA into receiving in both end stations in order to provide signal for the new CNS II as well as a BNC cable from receiving to CER to deliver the CNS II 1PPS signal to the third time difference port of the Timing Comparator located there. The cable lengths for the 1PPS signals are the same to within an inch.
