ALMA Memo #298

Timing and Synchronization


Larry R. D'Addario
13 March 2000

This report describes the current design of the timing distribution subsystem for the ALMA telescope, including facilities for synchronizing everything from the highest frequency local oscillators to the slowest switching cycles. Also considered is the need to maintain accurate knowledge of the relationship of the telescope's internal measure of time ("array time") to external measures like international atomic time.
