8.5 Polarization Controller VIsThe following VIs can be used to control the polarization controller (ap-plicable to A2xxx and A3xxx) in your application, i.e. to set all importantcontrol parameters and to start and stop the different scrambling modes.8.5.1 MIP PolConSettingsThis is the central VI to control the different modes of the polarizationcontroller. All necessary parameters to start the polarization controllercan be specified according to the following list:Input parameters: Device descriptor, scrambling mode, time-base, synchronization, sequence starttrig-ger, repetition rate, divider, holdoff de-lay,sequence lengthOutput parameters: Device descriptor, error codescrambling mode• Off (turns off all scrambling modes)• Random (scrambling with a pseudo random sequence)• Sequence (scrambling with user definable sequence)timebase• Internal Timer (uses polarization controller timer)• Polarimeter Clock (uses polarimeter timer for synchronization pur-pose, only valid on A2000 and A3300)• External Trig-In (uses external trigger input #1)synchronization• Auto Repeat (scrambling sequence is processed repeatedly)• OneShot (scrambling sequence is processed just once. The polar-ization controller remains on the last table entry)sequence starttrigger• Auto (scrambling sequence is untriggered and started by software)64 A1XXX/A2XXX/A3XXX User Guide
