LIGO Document E050262-v1
- The following Test Procedure describes the test of proper operation of the Timing Slave board (LIGO-D070071, thereafter, Slave). Slaves provide 1PPS/UTC synchronous timing and diagnostic signals to external devices that are needed to be synchronized in different, possibly distant parts of the detector. The Slave receives 1PPS/UTC synchronous timing signal from a FanOut or Master upstream (LIGO-D070011) that it synchronizes to.
