Synchronizing Sources
You can use synchronization to simultaneously perform operations
(for example, wavelength adjustments) on many IQS-2400 WDM Laser
Source modules. The sources can be synchronized with a signal coming
from an external instrument or from an other IQS-2400 WDM Laser Source.
To synchronize your source module with another instrument:
1. Connect a BNC cable from
³
the external device to the Sync. In TTL port of the first source
module.
OR
³
the Sync. Out port of the synchronizing IQS-2400 WDM Laser
Source to the Sync. In TTL port of the sources to be synchronized.
2. Use a BNC-T connector between each Sync. In port if more than one
source needs to be synchronized.
