You can select the desired calibration data set by right-clicking on thepolarimeter (you may have to click on the ”Objects” button in the toolbarto show the object browser) and clicking on ”Properties”.Go to the tab ”Calibration” and select the appropriate calibration dataset.6.6 Application: Continuous ScramblingUse this application to scramble the polarization state using an A3xxxinstrument or an A2000.The LiNbO3 waveplates are controlled in a way that creates a continuousmovement of the output polarization state.After activating this application, you can start and stop the scramblingprocess. The parameter scanrate defines the scrambling speed. An esti-mation of the resulting scrambling speed is given in the status field.The scanrate settings 1-8 correspond approximately to the scanrate set-tings of the Agilent 11896 polarization controller.See also Automation: Continuous Scrambling (section 11.11)6.7 Using Multiple Laser SourcesIt is supported by the software to connect several laser sources to theGPIB port of the computer or the instrument (configure these lasersources to different GPIB adresses). However, the applications can onlycontrol one laser source at a time. Therefore, you can add the same ap-plication twice to the browser window and associate the two applicationswith two laser sources.Use, for example, the following steps to configure the PDL/PMD-Application (section 6.2) for two laser sources:• Run the wizard to perform the automatic configuration. Your twolaser sources should be listed under Misc.Instruments.• Double-click on the PDL/PMD-Application (section 6.2) . You willbe asked for the laser source you want to use together with thisapplication. This configuration will also be used for the next timeyou start the application.• Exit the application.• Rename the application by right-clicking and selecting Rename orby clicking on the entry once again. Choose a name describing thelaser source (e.g. ”C-Band”)• Add the same application again by right-clicking in the browserwindow and choosing Add. Choose adaptif PHOTONICS SweptPDL/PMD Test.• Double-click on the new application and choose the other lasersource.• Exit the application.• Rename the application.Note: Once the link to an instrument is stored, it can only be changedby deleting the application and re-adding it again.A1XXX/A2XXX/A3XXX User Guide 57
