The factory default setting is this mode.
An external reference signal received through
GENLOCK IN on the rear panel is used.
If the external reference signal is lost during operation,
the frequency immediately before the signal is lost is
maintained. (Stay-in-sync function)
During stay-in-sync operation, even if the external
reference signal returns, the LT 4600A will not lock back
on to the external reference signal until the LT 4600A is
instructed to do so from the front panel.

When genlock is complete, EXTERNAL appears under LT4600A LOCK STATU S, and
EXT under REF lights in green.
In genlock mode, use the LT 4600A in this condition.
If an error occurs in the external reference signal in the EXTERNAL state, the frequency
that was in use immediately before the error occurred is maintained (stay-in-sync
function).
Under LT4600A LOCK STATU S, STAY-IN-SYNC appears, and EXT under REF blinks in
red.
In the STAY-IN-SYNC status, even if the reference signal returns, the LT 4600A will not
