N4374B Lightwave Component Analyzer, User’s Guide
Verifying the Optical Connections and Optical CW Operation
Passing these tests ensures that the transmitter and receiver are
within expected optical CW performance.
1. Follow the steps in the sections “Preparation ” on page 30
and “Network analyzer settings and electrical calibration” on
page 30.
2. If you have option -021:
Making sure the angled connector connects to the optical test
set, connect the two straight-angled optical patchcords
(N4373B-87907) to the optical output and input 1 (“+7 dBm”)
or input 2 (“+17 dBm”).
Use the FC/PC adapter (1005-0256) to connect the straight
ends of the optical patchcords together.
If you have option -022:
Making sure the angled connector connects to the optical test
set, connect the angled-angled optical patchcords (N4373B-
87906) to the optical output and input 1 (“+7 dBm”) or input
2 (“+17 dBm”).
Use the FC/APC adapter (1005-1027) to connect the angled
ends of the optical patchcords together.
3. Press the [Macro Setup] key on the front panel of the network
analyszer, then select , to see .
4. Press to start the LCA measurement setup.
5. Select the OO measurement tab.
6. Set the following parameters:
• If you have option 102 (Dual wavelength 1310nm,
1550nm), set Wavelength to the wavelength at which you
are testing your DUTs (1310nm or 1550nm).
