6.2 Signal Input (Genlock Operation)
Genlock refers to the act of establishing synchronization using a reference signal. Here, the
operation in the following five modes is explained according to the following flow of steps.
Internal mode: Mode in which an internal signal is used as a reference signal
(factory default value)
Genlock mode: Mode in which an external analog sync signal is used as a
reference signal
CW mode: Mode in which an external 10MHz CW signal is used as a
reference signal
GNSS mode (SER01): Mode in which an external GNSS signal is used as a reference
signal
PTP mode (SER03): Mode in which a PTP signal is used as a reference signal
1. Setting
2. Input of a reference signal
3. Lock
4. An error occurs in the reference signal
5. The reference signal is restored
6. Relock
The operation performed when the reference signal is restored differs depending on RECOVERY
MODE on the REFERENCE CONFIG menu. When RECOVERY MODE is set to AUTO, relock is
automatically performed. When it is set to MANUAL, relock is not performed. Here, the
operation performed when the mode is AUTO, in which relock is automatically performed, is
explained.
