How to Set the Maximum Power for the Sweep Range
Pressing [Pmax/Swp] sets the power to the maximum for the selected
sweep range. Alternatively, you can set a power level in the way described
in How to Set the Output Power of a CW Signal on page 134. Pressing
[Pmax/Swp] ensures the power will be constant for the whole sweep.
How to Perform a Sweep
There are three sweep modes:
• <
Stepped >, which dwells at wavelengths that are separated by a
certain step size,
• < Continuous >, which sweeps continually at the speed you set, and
• < Manual >, which you can run each step manually.
How to Execute a Stepped Sweep
To execute a stepped wavelength sweep over the range 1510 nm to 1570
nm, three times, sweeping two ways, in 1 nm steps, stopping for half a
second at each wavelength step:
1 Move to the Tunable Laser channel and press [Details].
2 Move to [
Sweep Mode ] and press Enter .
3 Move to the < Stepped > sweep mode and press Enter .
4 Move to
[

5 Enter 1510.000 and press Enter .
6 Move to

Stop ] and press Enter .
7 Enter 1570.000, press Enter .
8 Move to [ Cycles ] and press Enter .
9 Enter 3 and press Enter .
10 Move to [ Repeat Mode ] and press Enter .
11 Move to < Twoway >, by using the cursor key, and press Enter .
12 Move to
[
Step ] and press Enter .
13 Enter 1.000 and press Enter .
NOTE
You cannot turn the laser off by pressing the Active hardkey on the
Tunable Laser front panel, while a wavelength sweep is running.
You can press [Stop] and, then, press the
Active hardkey on the Tunable
Laser front panel, to turn off the laser.
