the power will be less than or equal to the maximum power possible
for the chosen Tunable Laser module across the chosen wavelength
range.
15 Move to [
Method
], press
Enter
, and move to one of the following sweep
modes:
•
<
Stepped
>, which dwells at wavelengths that are separated by a
certain step size, or
•
<
Continuous
>, which sweeps continually at the speed you set.
•
Press
Enter
.
[Dynamic]
The [
Dynamic
] parameter, which is only relevant for <
Continuous
> sweep
mode, allows you to achieve a higher dynamic range than is possible using
one wavelength sweep. Depending on the menu item you choose, the
Tunable Laser will be swept once, twice, or three times and the chosen
Power Meters will be set to different power ranges for each wavelength
sweep. The sweeps are combined using a "stitching" process to generate
the final results.
This feature is useful when you wish to measure the transmission
characteristics of a component that transmits or absorbs specific
wavelengths selectively, for example, a Fiber Bragg Grating.
16 Move to [
Dynamic
], press
Enter
, and move to one of the following:
•
<
Low
>, the wavelength is swept once, achieving a lower dynamic
range but sweeping more quickly,
•
<
Medium
>, the wavelength is swept twice, achieving a medium
dynamic range and medium speed, and
•
<
High
>, the wavelength is swept three times, achieving a higher
dynamic range but sweeping less quickly.

17 If your Tunable Laser module has two optical outputs perform the step
below.
Move to [

Enter
. Use the Modify Knob to move to

NOTE
Continuous sweep mode is not available for the 81609A, 81689A,
81949A, 81950A, 81989A Tunable Laser module.
