Ngaba uyayazi ngenene malunga neeSkena zeDijithali?

NjengeNkangeleko yoVavanyo lweNdlela eqhelekileyo, iSikena seDijithali sibonakalisa ngokwenene iNdawo engenacingo yoMmandla woVavanyo.Isetyenziswa kwi-CW (i-Wave eqhubekayo) yoVavanyo lweSignali, uVavanyo lweNdlela yokuPhucula iNethiwekhi, kunye nomsebenzi woPhuculo lweNethiwekhi kwiiNkqubo zoSasazo lweGumbi.

Makhe sijonge kwiiParameters eziqhelekileyo kunye neMigaqo yeXesha kunye neCandelo leSikena seDijithali ukuphazamisa uPhando.

IiParameters ezibalulekileyo zeSkena seDijithali ziquka iSetingi ze-Attenuator yangaphakathi, i-RBW (i-Resolution Bandwidth) imimiselo, i-Frequency Band size Settings, njl.

Umgaqo woSeto lwe-RF ye-Attenuator yangaphakathi ngulo:

(1) Xa Kuyimfuneko Ukukhangela Iimpawu ezincinci, iXabiso lokuNxibelela kufuneka libekwe ngokuphantsi kangangoko kunokwenzeka, ngaphandle koko iSignali ekujoliswe kuyo ePhandiweyo iya kuginywa yingxolo engezantsi ye-Frequency Scanner kwaye ayinakubonwa;

(2) Xa Kuyimfuneko Ukuchongwa kweMiqondiso Eyomeleleyo, Ixabiso Lokuthotyelwa kufuneka Libekwe phezulu kangangoko kunokwenzeka, kungenjalo liya kubangela ukugqwetheka okungahambelaniyo kwiSekethe yeSkena, ibonise iMiqondiso yobuxoki, kwaye Nokonakala inkangeleko;

Imigaqo yokuSeta i-RBW yile:

(1) Xa Ukukhangela Iimpawu ezincinci ze-Narrowband, ixabiso le-RBW kufuneka libekwe ngokuphantsi kangangoko kunokwenzeka, ngaphandle koko iSiginali yokuJonga iTarget iya kudibaniswa kwaye ayinakuhlukaniswa, kwaye iphinde iginywe ngumsindo we-scanner kwaye ingabonakali ngokupheleleyo;Kodwa ukuba ixabiso le-RBW liphantsi kakhulu, ixesha lokutshayela liya kuba lide kakhulu kwaye amandla okuvavanya ayakuchaphazeleka;

(2) Ithathela ingqalelo into yokuba iBandwidth yeRB enye ye-GSM Signal, iPHS Signal kunye neTD-LTE ikufuphi ne-200K, kunye namandla ovavanyo ngokubanzi, kuyacetyiswa ukuba i-RBW yesikena imiselwe ukuya kuma-200KHz.

UmGaqo wokuSeta ubungakanani bebhendi yefrikhwensi ngulo:

(1) Ngokusebenzisa iNtsebenziswano yoHluzo, Misela i-Frequency Band Scale kwi-LTE System Bandwidth Scale ukuPhanda i-In-Band Interference Conditions, ezifana ne-F-Band TDS In-Band Interference, i-GSM Second Harmonic Interference, kunye ne-DCS Intermodulation Interference.Kuyacetyiswa ukuba uQhagamshele isihluzo se-Frequency Band xa utshayela iFrequency.Umzekelo, uPhando lwe-F-Band Scrambling lumiselwe ku-1880-1900MHz.Xa Utshayela i-Frequency, naliphi na izibuko le-eriyali linokungadityaniswa kwi-RRU, iQhagamshele isihluzi, kunye nokuQhagamshela iSibuko sokuPhumayo seSihluzi kunye neSikena seFrequency Scanner;

(2) Tshayela iBand yeFrequency ePhezulu naPhantsi kweNdawo ekuJoliswe kuyo ukuPhonononga ukuba ingaba kukho imiSebenzi yeMiqondiso yeNkqubo eyahluka-hlukileyoUmzekelo, xa uPhanda uphazamiseko lwe-F-Band, unokuseta isikali sebhendi yokutshayela 1805MHz-1920MHz, kwaye uPhande i-1805-1920MHz ngokwahlukileyo.NgokoMqondiso kunye nobunzulu be-1830MHz, 1830-1850MHz, 1850-1880MHz, kunye ne-1900-1920MHz yeebhendi zokuphindaphinda, Phanda Amandla oMqondiso we-DCS ngokoKuphazamiseka kweWaveform ukuNcedisa ukufumanisa ukuba kunokubakho ukuphazamiseka okugcweleyo kunye ne-DCS egcweleyo;

Ukudibanisa i-In-Band Interference Conditions kunye ne-Off-Off-Band Interference Conditions of the High and Lower Insurance frequencyncies in the above two steps , Isenokwenzeka ukuhlalutya Ubunzima obuhlukeneyo bokuphazamiseka kwi-Chaotic Scene apho uPhakamiso oluninzi lubekwe phezulu.
