aLIGO Timing System's Accuracy during O2

Document #:

LIGO-T1700297-v2

Document type:

T - Technical notes

Abstract:

We measured the time delay between aLIGO Timing Distribution System 1PPS and the Timing Diagnostic System’s CNS Clock II GPS clock’s and and a GPS-backed NTP server’s 1PPS signals for aLIGO's second observation run (O2). The Timing Distribution System performance was proper.
