Abstract (English)

THE CONSTRUCTION OF THE IDT PROTOTYPE II HAS BEEN CONCLUDED.TO ENHANCE THE EMC, TWO ELECTRONIC BOARDS REPLACING THE ELECTRONIC CIRCUIT UNIT, HAVE BEEN MOUNTED AND TESTED BY DELTA. THE FIRST PCB, THE EMITTER DRIVER BOARD, IS INTEGRATED IN THE TEST CHAMBER BETWEEN THE LONG RANGE- AND NORMAL RANGE EMITTER POSITION. THE OTHER PCB IS INCLUDED IN ONE OF THE TWO BOXES WHICH HAVE BEEN ADDED TO THE ENDS OF THE CHAMBER. THE TWO BOXES ON EACH END OF THE MEASURING CHAMBER GUARANTEE THE CORRECT FUNCTIONING OF THE MEASURING SYSTEM. INDICATORS HAVE BEEN REDESIGNED TO SHOW OVERLOAD AND A TOTAL SUPPLY VOLTAGE INDICATION.AFTER A CORRECTION WITH SHIELDING IN SOME COMMERCIAL CABLES THE REMAINING EMC MEASUREMENTS SHOW GOOD RESULTS. IN THE WORK WITH THE REDESIGN OF THE SOFTWARE, SOME WEAK POINTS IN THE OLD ROUTINES HAVE BEEN REVEALED AND IMPROVED. NICE DETAILS LIKE ESTIMATION OF THE ELAPSED TIME FOR THE MEASUREMENT BEFORE YOU DESIDE THE SET UP OF THE MEASUREMENT, AND A ONGOING ADJUSTMENT OF THE TIME BAR SHOWING THE RESIDUAL MEASUREMENT TIME FOR THE CHOSEN MEASUREMENT PARAMETERS ARE INCLUDED.NOW THE IDT PROTOTYPE II IS READY FOR THE 'ROUND ROBIN' TEST BY THE PROJECT-PARTNERS LIKE THE MANUFACTURERS AND THE TEST-LABORATORIES.
