14.4.2 Step-adjusting the Wavelength/Frequency Value of the Module
Subject The following procedure explains how to modify the wavelength/frequency of the
module step by step using the increment defined in the Set Step sub-menu.
The starting wavelength is the value originally defined in the Set
λ
/f menu (see section
Specifying the Optical Emission Wavelength/Frequency, p. 210 ).
Procedure 1. Access the TLS-50 Unit Setup menu (see section Accessing an OSICS Module Setup
Menu, p. 33 ).
2. Expand the Step menu and enter the Set Step sub-menu.
The Set Step sub-menu appears and displays the current value of the channel step
and the corresponding step in GHz.

3. Modify the step value as follows:
a. Turn the rotary knob to put the cursor under the digit you want to modify and
press the knob to highlight it.
b. Turn the knob clockwise to increase the value or anticlockwise to decrease it and
press the knob to validate the selected digit.
c. Perform steps a. and b. again with the other digits to modify.
d. Press the
ENTER control button to go back to the Unit Setup menu.
The Unit Setup menu is automatically displayed.
4. To increase or decrease the wavelength/frequency value defined in the Set
λ
/f menu
(see section Specifying the Optical Emission Wavelength/Frequency, p. 210 ) step by
step, expand the Step menu and put the cursor before the Step + or Step - sub-
menus and press the knob to step-adjust the value.
While the module is updating the wavelength/frequency, the message
Moving…
appears along with the new wavelength/frequency value after step-change.
5. Repeat step 4. until the wanted wavelength/frequency is reached.
