Adjusting the Power Monitor

Adjusting the Power Monitor
Perform this procedure when the system is first installed; it does not need to
be performed before each individual measurement. In the following proce-
dure, you'll need an optical power meter.
1 On the System menu, confirm that the Wavelength Meter command is checked.
The check mark can be toggled on and off by clicking the command.
2 Connect a short "through" fiber-optic cable between the front-panel SOURCE
OUTPUT to RECEIVER INPUT connectors.
3 Click the Modulator Bias button.
The modulator is automatically biased to the optimum (quadrature) perfor-
mance condition. Bias adjustment is performed at the beginning of a measure-
ment session. It does not need to be performed before each individual
measurement. Bias adjustment can be set to occur automatically when a nor-
malization is performed.
4 On the Service menu, click Power Monitor Settings.
For dual band systems, enter high band values in the following steps. If you
have a single band system, perform these steps to enter the values for the sin-
gle available band.
