6.6 L-SYNC
L-SYNC refers to a function whereby, in a redundant system, the primary and backup
instruments, synchronized with the same analog sync signal, can be synchronized in time with
each other.
The following explains how to use it, considering the following system as an example.
Figure 6-3 | L-SYNC
1. Connect the L-SYNC connectors of the LT4670s with an L-SYNC cable.
For the L-SYNC cable, use the LC2186 (sold separately).
2. Apply an analog sync signal to one of the GENLOCK/CW IN connectors of each of the
LT4670 (primary) and the LT4670 (backup).
Apply the same analog sync signal to the primary and backup instruments. Terminate the
unused connector of each of the primary and backup instruments at 75 Ω.
