N4373D Lightwave Component Analyzer, User’s Guide 45
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 38
and “Network analyzer settings and electrical calibration” on
page 38.
2. On the network analyzer make the following settings:
• IF bandwidth: 100Hz
• 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 1.85 mm (N4697-60200) or 2.4mm (85133-
60017) Flexible Cables for Test Ports supplied to the
electrical ports of the N4373D Lightwave Component
Analyzer.
5. Press the [Macro/Local utility button until you see .
6. Press to start the LCA measurement setup.
