TB8100 Calibration Kit User’s Manual Calibrating the Exciter 17Calibrating the ReciterThe reciter is fully calibrated in the factory, but if the reciter is serviced you mayneed to perform the following procedures: Calibrating the Exciter Calibrating the RSSI Audio Calibration Calibrating the TCXOThese procedures can be done independently of each other, although it isrecommended that you tune the receiver before you calibrate the RSSI.Important: It is recommended that only accredited service centersand Tait engineers perform these procedures.AdvancedTroubleshootingAll the commands sent and received by TB8100 Calibration Kit are saved in afile called “CCTM.log”. The date, time, command number, and parameters areall stored in this file, which may be helpful when troubleshooting.The file is saved in the Logfiles folder (..\Program Files\Tait ProgrammingApplications\TB8100 Service Kit\LogFiles), and stores up to 1000 of the mostrecent logged items.Calibrating the ExciterYou will need to calibrate the exciter if you have made component-level repairsto it. There are three steps:1. Auto-tune the FCL2. Calibrate the FCL modulation3. Calibrate the VCO modulationAutomatically Tune the Frequency Control Loop (FCL)This is step one of calibrating the exciter.Low frequencies (CTCSS and DCS) are modulated using the FCL (frequencycontrol loop). The FCL forms a loop that allows the reference frequency to bemodulated.To automatically tune the FCL1. Ensure you are already connected to the reciter.2. Select the Reciter Calibration tab, and double-click FCL Auto Tuning.The FCL Auto Tuning Wizard appears.3. Click Calibrate to automatically tune the FCL.The icon on the Reciter Calibration tab indicates that this task is complete.You will now need to calibrate the FCL modulation.Calibrating the FCL ModulationThis is step two of calibrating the exciter. Once you have auto-tuned the FCL,you should calibrate the FCL modulation.Equipment Tuning tool |
