1. Unganquma kanjani uhlobo lwesixhumi
Okufanele uxhumeke futhi kuphi ukusetshenziswa kwalezi zindaba yizo ezocatshangelwa kuqala, okunquma uhlobo isixhumi sezimboni ezikhethiwe. Ikheli lapho kusetshenziswa khona isixhumi (yasendlini, ngaphandle, indawo ebolayo, njll.) lizothinta ukuthi kuthuthukiswe ukucinana kwepulaki yendiza noma ukumboza igobolondo ngaphandle komzimba wokushisa. Uhlobo lwesixhumi lunquma ukuthi iyiphi itheminali okufanele uyikhethe nokuthi mangaki amatheminali okuqhuba okufanele ahlelwe.

2. Izidingo zemvelo
Izinga lokushisa, umswakama kanye nezinye izimo zemvelo kunqunywa indawo yesixhumi sikagesi, ngakho indawo nendawo elindelekile kufanele kucatshangelwe. Sithini isikhathi esisebenzayo kanye nolwazi lwezinye izimo zesitoreji ezifanele. Incazelo yendawo ezungezile kufanele futhi ihlanganise izidingo zokushaqeka kanye nomuzwa, kuhlanganise nalezo ezisuka ezithuthweni zasolwandle, kanye nezidingo zokukhiqiza izimo zemvelo ezifana nezinga lokushisa lokushisela kanye nobude besikhathi somjikelezo wokushisela. Umkhiqizi wesixhumi ubonisa ukuthi indawo ezungeze imanje eguqukayo eqhubekayo esekelwa isixhumi indawo lapho izinga lokushisa elingu-Z lenzeka khona.
3. Izidingo zikagesi
Lapho ukhetha isixhumi sikagesi, izidingo zikagesi zomkhiqizo zizocatshangelwa. Yiziphi izidingo ze-voltage nezamanje zomkhiqizo, nokuthi isixhumi singasetshenziswa kahle yini kulezo zakhiwo zikagesi? Le mibuzo emayelana nezidingo zikagesi idinga ukucatshangelwa. Ukwengeza, sidinga futhi ukucabangela ezinye izimo zikagesi: ukumelana, ukushintshwa okuvumelekile kokumelana, ukwehla kwe-millivolt, inani lamanje elikhulu elingu-Z, inani elikhulu lamandla kagesi elingu-Z, inani lamanje le-inrush, i- characteristic impedance, (isilinganiso se-voltage esima igagasi), ukusebenza kahle kokuxhuma kokulahlekelwa kokuxhuma.
