Tunable Laser Source 31

Setting the Sweep Step

You can set the size of the step (in nm or THz) for your step-by-step sweep.

Your tunable laser source unit was designed to give a constant step value

using nm as units. When steps are given in THz, the selected step value

represents the average value of the steps during the sweep, since an

interval in nm does not always have the save equivalent value in THz

according to the wavelength bandwidth you have selected.

To set the step:

1. Make sure you have selected the step-by-step sweeping mode (as seen

in Selecting the Sweep Mode on page 30).

2. Press Sweep.

3. Turn the selection dial clockwise until STEP is displayed.

4. Press ENTER. The Edit marker starts blinking in the lower part of the

display.

5. Turn the selection dial clockwise or counterclockwise to select the

desired size for the step.
