1 Far Fild Estimations and Simulation Modl Cration from Cabl Bundl Scans D. Rinas, S. Nidzwidz, S. Fri Dortmund Univrsity of Tchnology Dortmund, Grmany Abstract Th mission lvl of automotiv systms is oftn govrnd by th cabl harnss, it is oftn th dominant radiating structur and dtrmins th position of rsonancs. Th stablishd fild masurmnt mthods according CISPR 5 for valuation of missions suffr from th nd to us larg anchoic chambrs. Furthrmor masurmnt data can not b usd for simulation modl cration in ordr to comput th ovrall filds radiatd from a car. In this papr a simpl mthod to dtrmin th far-filds and a simulation modl of a radiating cabl bundl from nar-fild masurmnts is proposd. Th mthod masurs th lctromagntic filds at svral points nar to a cabl bundl. Masurmnts ar don in tim domain in ordr to gt phas information, to rduc masurmnt tim, and to corrlat diffrnt masurmnt data sts. From th fild masurmnt data an quivalnt currnt distribution in a cabl bundl can b computd. With this information a simulation modl of th stup can b gnratd, far-fild stimations can b don. I. INTRODUCTION Elctromagntic Compatibility plays an important rol in th dvlopmnt of automotiv lctronic systms. Th intgratd Elctronic Control Units (ECUs and spcially th mainly usd unshildd cabl bundls ar sourcs for lctromagntic missions. Standardizd componnt fild masurmnt mthods, lik th ASE antnna mthod providd in CISPR 5 [] for valuation of lctro-magntic missions from automotiv systms, suffr from th nd of larg and xpnsiv anchoic chambrs. Also a singl fild strngths valu is oftn not sufficint to charactriz th EMI bhavior of a complx systm. Furthrmor it is not possibl to us th masurmnt data for bhavioral modl cration for simulation. Having simulation modls, a statmnt about th radiating lctromagntic filds can alrady b mad in arly phass of dvlopmnt. Basically th lctromagntic mission must b distinguishd in th mission from circuit boards and thir housing and th mission from th conncting cabl bundls. To b abl to dtrmin th radiatd far filds it is ncssary to transfr th radiating ECU structur and th attachd cabls into an quivalnt bhavioral modl with rducd complxity. Knowing th filds in an indfinitly xtndd plan abov th tst objct all information is availabl to calculat any fild vctor abov this plan []. From thortical point of viw this would b sufficint to calculat th far filds. Thr ar svral problms with such an approach. E.g. accuracy of masurmnts is limitd and accuracy of fild calculation can b low. It is bttr to try to solv th invrs problm and thus to idntify by th masurd fild important proprtis of th tst objct. This approach is discussd in [3], [4], [5] and []. Focus is placd mainly on PCBs. Howvr, considring th small structur siz of most automotiv PCB and housings and compar it with th wavlngths in th frquncy rang blow MHz, radiation from cabls is oftn th dominant mission factor. To charactriz complx cabl bundls with standard voltag and currnt masurmnts on ach singl cabl is oftn not fasibl. This papr prsnts a spcial mthod for stimating th missions from cabl bundls. Th lctromagntic nar-fild at svral points nar a cabl bundl is masurd. With masurd dat an quivalnt currnt distribution in th bundl is calculatd and a simulation modl can b cratd. Th gnratd modl nabls diffrnt typs of post-procssing.g. far fild stimations. Th mthod can b combind with scans of th PCB and th nclosur structur, in ordr to dtrmin th full systm bhavior and to crat bhavioral modls for larg systm simulations. Accurat sourc idntification rquirs phas information [], most groups working on scanning mthods don t discuss this problm. In [3] an approach basd on frquncy domain masurmnts is prsntd. Disadvantags of th mthod ar th high complxity and masurmnt tim. In this papr a tim domain approach with a standard oscilloscop is prsntd. Advantags ar, th dirct availability of th phas information, th possibility to masur 4 fild componnts simultanously, i.. synchronizd, and th fastr simulation tim. II. SCANNING METHOD FOR SYSTEM CHARACTERIATION Typical automotiv systms consist of on or mor ECUs and thir conncting cabl bundls (Figur. Ida of th prsntd approach is to stimat th lctro-magntic filds of an automotiv cabl bundl by crating a bhavioral modl basd on scannr-masurmnt data. Th ECUs ar considrd hr as black boxs, using a linar bhavioral modl approach. As th voltag amplituds of RF-disturbancs ar oftn not big,

2 small signal approachs ar valid and linar modls can approximat th mission bhavior of th lctronic systm. In th approach prsntd hr, ECUs ar considrd as non radiating lumpd circuits. An xtnsion with radiating structurs is possibl, but not discussd in this papr. ECU Figur. Systm to invstigat For crating th bhavioral modl th currnt distribution on cabl bundl must b approximatd. Complx nar fild data is collctd at svral points on lins paralll to th bundl. Thrfor th masurmnts ar don in Tim Domain, followd by a transformation in Frquncy Domain for furthr procssing. With H ( z I ( z πd π (h + d th corrlation btwn th magntic fild and currnt distribution is givn for a long homognous cabl placd clos abov a ground plan. Whr d is th distanc from bundl to masurd fild point and h is th hight of th cabl bundl abov th ground plan. Th closr to th cabl th filds ar masurd th highr is th accuracy of (. Th hight h is also assumd to b small. Th modl cration procss is prsntd in Figur.

Tim Domain - Frquncy Domain Transformation Tim domain masurmnts hav svral advantags discussd abov. For th following post-procssing I z is transformd in th frquncy domain. For obtaining th Frquncy Domain information of a masurd Tim Domain signal th Fourir-Transformation is usd. This transformation provids th complx information in a continuous Frquncy Domain, from which spctrum and phas information can asily b drivd. Furthrmor th Fourir-Transformation is fully rvrsibl. F jωt x( t dt { x( t } X ( ω As th continuous Fourir-Transformation rquirs continuous Tim Domain data it is not usabl in cas of digital signal procssing. Thrfor th Tim Domain data is discrtizd at fixd tim stps according to a chosn sampling frquncy that should b idntical to th scop sampling frquncy. t f S Additionally, th chosn sampling frquncy spcifis th maximum frquncy dtctabl by th Fourir-Transformation, which is limitd by th Nyquist-Thorm. f max Hnc all frquncy componnts highr than f max should b supprssd by a low-pass filtr to avoid problms originating from Alias-Effct. In this cas th transformation is known as Discrt Fourir Transformation (DFT F d { } s( n S( k f s( n t f S N kn jπ N Th DFT is working on a fixd lngth data squnc s(n that is assumd to b rpating priodically. Th lngth N of th sampling squnc hrby dfins th discrt frquncy rsolution of th DFT. f S f N N t smi-rigid coxial cabl (5 Ω SMA connctor (4 (5 (6 (7 (8 For achiving good rsults th frquncy rsolution should b chosn as an intgr dividr of th most intrsting frquncy, but in gnral th frquncy componnts of a signal ar not known prior to th masurmnt. An fficint ralization of th DFT is achivd by th Fast Fourir Transformation (FFT, which taks advantag of symmtris along roots of unity usd in th calculation. Diffrnt algorithms for th FFT xist, which mainly diffr in thir fficincy concrning diffrnt input squnc lngths N. Anothr aspct in th usag of th DFT is th windowing of th original squnc in Tim Domain. Th input squnc s(n itslf can b undrstood as part of th original masurmnt data windowd by a rctangular function of lngth N. s( n x( n w ( n Th multiplication of th data squnc with a window function in Tim Domain corrsponds to a convolution of th transformd data squnc with th transformd window function in Frquncy Domain. N { x( n } F{ w( } S( k F n (9 ( This causs a crtain distortion in th Frquncy-Domain rsult dpnding on th usd window function which is also known as akag-effct. To obtain th ncssary prcision of th frquncy data usd in this work, without wasting computing tim, masuring tim and mmory, th frquncy rsolution f is carfully chosn btwn. and. tims of th dsird minimum frquncy. To furthr optimiz ths fficincis critria th sampling frquncy f S is chosn in rlation to th dsird maximum frquncy. In Figur 6 masurmnt rsults of a pulsd input signal into a singl cabl mad with a tst rcivr can b sn. Hr th puls has an amplitud V V, a fundamntal frquncy of f MHz, a puls/paus ratio t h /t l. and a rising and falling dg of t r,f.5 ns. In comparison th rsults from th FFT basd on a Tim Domain masurmnt ar shown in Figur 7. Hnc, th FFT rsults ar vry accurat. Th main diffrncs btwn both mthods ar th nois floor lvls causd by th masuring dvic and th spctrum shap around th paks causd by rsolution bandwidth (RBW and window shap. As xplaind abov th dynamics of th FFT-mthod mainly dpnd on th usd sampling frquncy and th duration of th masurmnt. Thortically any frquncy rsolution blow th Nyquist-frquncy (6 can b achivd. Th signal s shap and frquncy do not hav considrabl ffcts on th rsult in gnral. A physically limiting factor to th rsults is st by th usd masurmnt dvics, mor prcis its nois floor lvls and attnuations. Th diffrnc in th amplitud valus, which is quit constant along th spctrum, is xplaind with th masurmnt mthod itslf. Th tst rcivr masurs th ffctiv valu, whras th usd FFT calculats th pak valus of th Fourir componnts of a givn signal.

Equivalnt Transmission in Modl To approximat th cabl bundl bhavior a singl transmission lin modl with quivalnt currnt distribution is gnratd.

Basd on ths input paramtrs th trminating impdanc (Figur can b calculatd as V I (3 whr V and I ar voltag and currnt at th nd of th transmission lin.
