To enable external digital modulation:
1 Move to the Tunable Laser channel and press [Details].
2 Move to [Mod Src] and press Enter.
3 Move to <External Digital> by using the cursor key, and press Enter. The text
ExtD appears in the Tunable Laser channel.
External Analog Modulation
External analog modulation uses a signal of up to 5 V
causes 15% modulation of the power of the optical signal. Apply this signal
to the input BNC connector on the front panel of your Tunable Laser
module.
There are two BNC connectors on the front panel of the Agilent 81480B,
Agilent 81482B, Agilent 81672B, Agilent 81680B, Agilent 81682B,
Agilent 81640B and Agilent 81642B - a BNC input connector and a BNC
output connector.
There is one BNC connector on the front panel of the Agilent 81689A - a
BNC input connector.
An absolute maximum of ±6 V can be applied as an external voltage to any
BNC connector.
