If the polarization is maintained, the total return power and the polarization power will lie within the specified optimized range (the default value is ±20%). In this case, âOptimization Indicator LEDâ becomes green. Otherwise, it start blinking and the information panel indicates: âPolarization is not maintained: Optimization is required.â A user can change the threshold from the box labeled âAuto Trigger Marginâ (see Figures 3.7 and 3.8). If the power difference is greater than 20%, the polarization state is found not to be maintained, therefore, the user will be prompted with a dialog window giving an opportunity to initiates the optimization process or skip the optimization by choosing âNo.â

<brp>The âStopâ button stops the application. To close (kill) the [[NeoScan]] window click on exit button [[Image:icon_Exit.png]] on the top far right in the LabView user interface. To re-start running the program press the start button [[Image:icon_Start.png]] located on the top left in the LabView window as shown in Figure 3.10. During the run, the start button will disappear. Keep [[NeoScan]] Optical Bench Manager program running until the end of the measurement. </p>
