Njengokubukeka Kokuhlolwa Komgwaqo Okuvamile, Iskena Sedijithali Sibonisa Ngempela Imvelo Engenazintambo Yendawo Yokuhlola.Isetshenziswa Ekuhloleni Izignali ze-CW (Igagasi Eliqhubekayo), Ukuhlola Umgwaqo Wokuthuthukisa Inethiwekhi, Kanye Nomsebenzi Wokuthuthukisa Inethiwekhi Ezinhlelweni Zokusabalalisa Amakamelo.
Ake Sibheke Amapharamitha Ajwayelekile Nezimiso Zesikhathi Nokwahlukaniswa Kweskena Sedijithali Ukuphazamisa Uphenyo.
Amapharamitha Abalulekile Weskena Sedijithali Ahlanganisa Izilungiselelo Zesibaliseli Sangaphakathi, Izilungiselelo ze-RBW (Umkhawulokudonsa wokuxazulula), Izilungiselelo Zosayizi Webhendi, Njll.
Umgomo Wokusethwa Kwe-RF Attenuator Yangaphakathi Ngu:
(1) Lapho Kudingeka Ukusesha Amasignali Amancane, Inani Lokunciphisa Kufanele Libekwe Liphansi Ngangokunokwenzeka, Ngaphandle kwalokho Isignali Eqondiwe Eseshiwe Izogwinywa Umsindo Ongezansi Weskena Sefrikhwensi Futhi Ingabonwa;
(2) Lapho Kudingeka Ukuthola Izimpawu Eziqinile, Inani Lokunciphisa Kufanele Libekwe Liphezulu Ngangokunokwenzeka, Ngaphandle kwalokho Lizobangela Ukuhlanekezelwa Okungaqondile Esekeleni Seskena, Kubonise Izimpawu Zamanga, Futhi Nokulimaza Ukubukeka;
Izimiso Zokusetha ze-RBW yilezi:
(1) Lapho Usesha Izimpawu Ezincane Ze-Narrowband, Inani Le-RBW Kufanele Libekwe Liphansi Ngangokunokwenzeka, Ngaphandle kwalokho Isignali Yethagethi Yosesho Izohlanganiswa Futhi Ingakwazi Ukuhlukaniswa, Futhi Igwinywe Ngomsindo Weskena Futhi Ingabonakali Ngokuphelele;Kodwa Uma I-RBW Value Iphansi Kakhulu, Isikhathi Sokushanela Sizoba Yinde Kakhulu Futhi Amandla Okuhlola Azothinteka;
(2) Ngokucabangela Ukuthi Umkhawulokudonsa We-RB Eyodwa Yesiginali ye-GSM, Isignali ye-PHS kanye ne-TD-LTE Isondele Ku-200K, Futhi Amandla Okuhlola Aphelele, Kuyanconywa Ukuthi I-RBW Yeskena Isethelwe Ku-200KHz.
Isimiso Sokusetha Usayizi Webhendi Ithi:
(1) Ngokubambisana Kwesihlungi, Setha Isikali Sebhendi Yefrikhwensi Esikalini Somkhawulokudonsa Wesistimu ye-LTE Ukuze Uphenye Izimo Zokugxambukela Kwebhendi, Njengokugxambukela kwe-F-Band TDS In-Band, I-GSM Second Harmonic Interference, Kanye Nokuphazamiseka Kwe-DCS Kokuphazanyiswa.Kuyatuseka Ukuxhuma Isihlungi Sebhendi Evumelanayo Lapho Ushanela Imvamisa.Isibonelo, Uphenyo Lwe-F-Band Scrambling Lusethelwe Ku-1880-1900MHz.Lapho Ushanela I-Frequency, Noma Iyiphi Imbobo Ye-antenna Inganqanyulwa E-RRU, Ixhuma Isihlungi, Futhi Ixhume Imbobo Yokuphuma Kwesihlungi Neskena Sefrikhwensi;
(2) Shanela Amabhendi Emvamisa Aseduze Aphezulu Naphansi Ebhendi Yefrikhwensi Eqondiwe Ukuze Uphenye Ukuthi Ingabe Kukhona Imisebenzi Yesiginali Ehlukile Yesistimu Kumabhande Angaphansi Ahlukene.Isibonelo, Lapho Uphenya Ukugxambukela Kwe-F-Band, Ungasetha I-Sweep Frequency Band Scale 1805MHz-1920MHz, Futhi Uphenye 1805-1920MHz Ngokuhlukana.Ngokuya Ngesiginali Nokuqina Kwe-1830MHz, 1830-1850MHz, 1850-1880MHz, Futhi 1900-1920MHz Amabhendi Emvamisa, Phenya Amandla Esiginali We-DCS Ngokuhambisana Nokuphazamiseka Kwe-Waveform Ukuze Usize Ukunquma Ukuthi Kungase Kube Nokuphazamiseka Okugcwele Kwe-DCS;
Ukuhlanganisa Izimo Zokuphazanyiswa Kwangaphakathi Kwebhendi Kanye Nezimo Zokuphazanyiswa Kwangaphandle Kwebhendi Zemvamisa Eseduze Engaphezulu Nangaphansi Ezinyathelweni Ezimbili Ezingenhla, Kuyenzeka Ukuhlaziya Izisindo Zokuphazanyiswa Ezahlukene Esigcawini Esinesiphithiphithi Lapho Ukuphazamiseka Okuningi Kwenziwa Khona.
