Performance Tests
The procedures in this section test the Agilent 83400-series performance
using the specifications listed in
Chapter 3, “Specifications and Regulatory
Information” as the performance standard. None of these tests require access
to the interior of the instrument. Before beginning any tests, be sure to
observe the following points:
• Use an optical cable with a Diamond HMS-10 connector. Other connector types
may have greater return loss or may cause reflections resulting in measure-
ment errors.
• Be sure that all optical connections are clean. Refer to “Cleaning Connections
for Accurate Measurements” on page 2-11 .
• Allow the source or receiver to warm up for 1 hour before doing any of the per-
formance tests.
W A R N I N G Do NOT, under any circumstances, look into the optical output or any
fiber/device attached to the output while the laser is in operation.
Calibration cycle
Agilent Technologies warrants instrument specifications over the recom-
mended calibration interval. To maintain specifications, periodic recalibrations
are necessary. We recommend that Agilent 83411C/D receivers be calibrated
at an Agilent Technologies service facility every 24 months. We recommend
that all other sources and receivers be calibrated every 12 months.
