9.3.2 Performing Real-time Adjustments to the Output Power
Subject The following procedure explains how to adjust the output power of the module in real-
time (within the accuracy determined by the smallest decimal-digit of the power value).
The starting power is the value defined in the
Set Power menu.
Before Starting Enable the optical output of the module (see section Enabling/Disabling the Light Source
of the Module, p. 103 ).
Procedure 1. Access the ECL Unit Setup menu (see section Accessing an OSICS Module Setup
Menu, p. 33 ).
2. Turn the rotary knob to put the cursor before the Adjust Power menu and press the
knob.
The
Adjust Power menu appears and displays the current power setting, with the
first digit highlighted.

3. Adjust the power value as follows:
a. Turn the knob clockwise to increase the digit value or anticlockwise to decrease it
and press the knob to validate the selected digit.
Rotating the knob increments or decrements the digit above the cursor. Going
above "9" increases the next significant digit; going below "0" decreases the next
significant digit.
b. Perform steps a. and b. again with the other digits to modify.
The module output power is updated in real time when you change the value in this
menu.
4. Press one of the following control buttons:
• ESCAPE : to validate the displayed value and go back to the ECL Unit Setup
menu.
• EXIT : to display the System Status screen.
The optical power value of the module is now modified (according to the module
power limits).
