2 Performance Tests
Performance Tests
The procedures in this chapter test the performance of
the Agilent 86121A using the specifications listed in
Chapter 7, “Specifications and Regulatory Information”
as the performance standard. All of the tests are done
manually without the aid of a computer. None of these
tests require access to the interior of the instrument.
Test 1. Absolute Wavelength Accuracy 6-4
Test 2. Sensitivity 6-5
Test 3. Polarization Dependence 6-7
Test 4. Optical Input Return Loss 6-8
Test 5. Amplitude Accuracy and Linearity 6-11
Allow the 86121A to warm up for 15 minutes before
doing any of the performance tests.
Calibration Cycle
This instrument requires periodic verification of perfor-
mance. The instrument should have a complete verifi-
cation of specifications at least once every year.
Connector Cleaning
Accurate and repeatable measurements require clean
connections. Follow the connector cleaning procedure,
refer to “Cleaning Connections for Accurate Measure-
ments” on page 8-11
, before proceeding with the per-
formance verification.
