| Operation Modes |
| INTERNAL |
Internal reference signal is used for operation. (INT mode) |
| AUTO (GO INTERNAL) |
| The EXT is automatically selected when the external reference signal is applied
to the GENLOCK input. The INT mode is automatically selected when the external
reference signal is removed. |
| MANUAL (GO INT) |
| The EXT mode is automatically selected when the external reference signal with
the same format specified to the GENLOCK input is applied after power is
turned on. The INT mode is automatically selected when no external reference
signal is applied to the GENLOCK input or signal format does not match the
specified format. |
| AUTO (STAYinSYNC) |
| The EXT mode is automatically selected when the external reference signal is
applied to the GENLOCK input after power is turned on.
If the external reference signal is accidentally removed during operation, the
instrument continues operation under the conditions immediately before the signal
is removed since STAYinSYNC mode is provided.
After the external reference signal is recovered, the system is automatically
locked. |
| MANUAL (STAYinSYNC) |
| The EXT mode is automatically selected when the external reference signal with
the same format specified to the GENLOCK input is applied after power is turned
on. If the external reference signal is accidentally removed during operation, the
instrument continues operation under the conditions immediately before the signal
is removed since STAYinSYNC mode is provided.
The STAYinSYNC mode will be held until the reset operation is performed via the
front panel even after the external reference signal is recovered. |
