N O TE Continuous sweep mode is not available for the Agilent 81689A Tunable Laser
module.
[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.
17 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 once, achieving a higher dynamic range
but sweeping less quickly.
Press Enter.
18 If your Tunable Laser module has two optical outputs perform the step below.
Move to [Optical Output] and press Enter. Use the Modify Knob to move to
one of the following:
– <High Power (2)>, a high power optical output, for example, for use in
tesing Erbium Doped Fiber Amplifiers (EDFAs), you see a screen similar to
Figure 65,
– <Low SSE (1)>, a lower power optical output with low Source Spontaneous
Emission (SSE), for example, for use in passive component test, you see a
screen similar to Figure 66,
– <Both (master:2)>, where both optical outputs can be enabled but only the
output of the high power optical output can be regulated, and
– <Both (master:1)>, where both optical outputs can be enabled but only the
output of the low SSE optical output can be regulated.
Press Enter.
