Operating Basics
Overview
To perform optical compensations
Control elements and resources
Run the
dark-level
compensation
4.
Click the
Dark Level
button under Compensation.
Follow the on-screen instructions.
5.
Repeat steps 2 through 4 for any additional optical
channels that you want to compensate.
If any of the following settings or conditions change after
performing a dark level compensation, perform another
compensation to maintain the speci
fi
ed accuracy.
Trigger rate setting
Vertical offset setting
Filter or bandwidth setting
Ambient temperature change of more than 1 °C
Run the user
wavelength
gain
compensation
You can optionally use a custom input signal to compensate
an optical channel:
6.
In the Vert Setup dialog box, click the
User
Wavelength Gain
button under Compensation. Follow
the instructions on screen.
In the User Wavelength Gain Compensation dialog
box, set the wavelength and power of the signal to
be applied to the channel.
7.
You must connect an optical signal to the module input
with a precisely known amount of optical power. Use
an independently calibrated average optical power
meter to precisely measure this power. Then connect
the signal to the module using the same
fi
ber cables.
8.
Click the
OK
button to execute the compensation.
9.
Repeat steps 2, 6, and 7 for any additional optical
channels that you want to compensate.
