Optical Sampling Modules
Setup
1.
Install the 80C0X Optical Sampling Module into Channel 1 of the instrument.
Figure 29: Minimum optical bandwidth and reference receiver frequency response setup
2.
Connect the 10 dB optical attenuator to the output of the optical impulse
generator.
3.
Connect a
fi
ber-optic cable between the 10 dB optical attenuator and the input
of the OA5002 variable optical attenuator.
4.
Connect a
fi
ber-optic cable between the output of the variable optical
attenuator and the OPTICAL INPUT of the optical sampling module.
5.
Connect a 50
Ω
coaxial cable from the rear trigger (SYN) on the optical
impulse generator to the TRIGGER DIRECT input on the instrument.
6.
Start with about 30 dB of attenuation on the variable attenuator.
NOTE.
To avoid dispersing the narrow optical impulse signal, keep all
fi
ber
lengths as short as possible. Lengths that are 2 to 3 meters long are acceptable.
7.
Push the
SELECT ON/OFF
button on the 80C0X Optical Sampling Module
so that the adjacent indicator lights. This turns on Channel 1 (C1) on the
80C0X-CR Optical Sampling Module.
8.
In the Setup menu, select Acquire and make the following changes in the
Acq Setup dialog box:
a.
Select
Average
as the acquisition mode.
b.
Set the number of samples to
64
Samples.
