(1)
t
phase
Maximum phase difference between signals. (This speciîž’cation is not affected by
any of the other speciîž’cations).
(2)
t
start
Maximum delay between start of recording of each mainframe.
(3)
t
stop
Maximum delay between stop of recording of each mainframe.
(4)
t
trigger
Maximum delay to transfer a trigger from a mainframe to all other mainframes.
(5) Note on trigger exchange
Trigger exchange is included in the Master/Sync connection cable. All other synchronization
modes require that the mainframes are connected from each External Trigger Out to each
External Trigger In on all mainframes in order to exchange triggers.
