Optional Performance Tests Performance Tests
Agilent 81600B Tunable Laser Source Family, Fourth Edition 135
Dynamic Wavelength Accuracy
Introduction
The procedures in this section test the wavelength accuracy of the Agilent
81600B Tunable Laser Source Family during a continuous sweep. The test
setup and the measurement phases are common to absolute and relative
wavelength accuracy, as well as wavelength repeatability; but the
computations are different. This is reflected in the structure of this
description.
Required Equipment
This test requires the 81637B Fast Power Meter and the Wavelength
Reference Unit (Fabry-Perot etalon). In addition, PnP drivers of version 3.5
or higher are required.
Test Overview
A short overview of the test procedure is shown as a flow chart in
Figure 41. The sections that follow provide more detailed explanation.
Software control required The performance verification of dynamic
parameters is extremely complex and needs to be done within a short time frame
under software control. The following describes the steps to be taken in detail and
gives hints to the calculations that need to be done by user defined software.
Due to the complexity of this test, it is strongly recommended to have the related
performance verification done in a dedicated Agilent service center
