N4374B Lightwave Component Analyzer, User’s Guide 37
Verifying the Electrical Connection and Electro-optical Operation
Passing these tests ensures that the internal transmitter and
receiver of the Lightwave Component Analyzer are within
expected electro-optical performance.
1. Follow the steps in the sections “Preparation ” on page 30
and “Network analyzer settings and electrical calibration” on
page 30.
2. On the network analyzer make the following settings:
• IF bandwidth: 300Hz
• Select “Reduce IF BW at Low Frequencies”.
3. 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.
4. Connect the two type-N Flexible Cables for Test Ports (8120-
8862) supplied to the electrical ports of the N4374B
Lightwave Component Analyzer.
5. Press the [Macro Setup] key on the front panel of the network
analyszer, then select , to see .
6. Press to start the LCA measurement setup.
