Setting a Predefined Increment/Decrement Step
Subject
The following procedure explains how to change the wavelength increment (STEP) value.
Procedure
1.
In the MODE area, press the
STEP
key.
2.
Using the numeric keypad, enter the wanted wavelength or frequency step.
Example for wavelength (nm): 0.5
3.
Make sure the value you entered is valid, as specified in section
.
The required output power may not be reached even at the maximum allowable
current. If this occurs, the TUNICS T100S-HP automatically limits the current to its
maximum value and the message
"Lim"
appears
4.
In the SETUP area, press the
ENTER
key.
5.
Increase or decrease the wavelength by pressing the
←
or
→
arrow keys in the SETUP
area
.
4.3
Using the Fine Scanning Mode (Fine Tuning)
Subject
The Fine Scanning Mode performs a complete and virtually continuous sweep of the
wavelength on a ±2 GHz range. It enables you to fine tune wavelength with a 0.1 pm
resolution. You first need to set the desired emission wavelength (resolution 1 pm) and
then adjust the value with the FSC function key (0.1 pm resolution), as described below.
Procedure
1.
To enable the Fine Scanning mode: in the MODE area, press the
FSC
function key
.
2.
Adjust the wavelength with the rotary knob over a limited range of about ±20 pm.
The wavelength offset selected with the rotary knob is displayed in the DATA area in
nm (d
λ
) or GHz (df).
3.
To exit the Fine Scanning mode, press the
FSC
function key again.
