Ngabe Uyazi Ngempela Ngezikena Zedijithali?

Njengendlela Ejwayelekile Yokuhlolwa Komgwaqo, I-Digital Scanner Ikhombisa Ngempela Imvelo Engenantambo Yendawo Yokuhlola. Isetshenziswa Ekuhlolweni Kwamasignali e-CW (Continuous Wave), Ukuhlolwa Kwezindlela Zokusebenzisa Inethiwekhi, Nomsebenzi Wokusetshenziswa Kwezinethiwekhi Kwamasistimu Okusabalalisa Amagumbi.

Ake sibheke imingcele ejwayelekile nezimiso zesikhathi kanye nokuhlukaniswa kwesithwebuli sedijithali ukuphazamisa uphenyo.

Amapharamitha Abalulekile Esithwebuli Sedijithali Afaka Amasethingi Wangaphakathi We-Attenuator, Amasethingi e-RBW (Resolution Bandwidth), Amasethingi Obukhulu Be-Frequency Band, Njll.

Isimiso Sokusetha Kwangaphakathi kwe-RF Attenuator Is:

(1) Uma Kudingekile Ukufuna Izimpawu Ezincane, Inani Lokuncishiswa Kwenani Kufanele Libekwe Phansi Ngokungenzeka, Ngaphandle kwalokho Isiginali Esihlosiwe Esizosetshenzwa Sizogwinywa Umsindo Ophansi We-Frequency Scanner Futhi Awunakubonwa;

(2) Uma Kudingekile Ukuthola Izimpawu Eziqinile, Inani Lokuncishiswa Kwenani Kufanele Libekwe Phakeme Ngokungenzeka, Ngaphandle kwalokho Lizodala Ukuhlanekezela Okungahambisani Nesikhathi Esikhungweni Se-Scanner, Khombisa Izimpawu Zamanga, Futhi Ngisho Nokulimaza Ukubukeka;

 

Izimiso Zokubeka ze-RBW yilezi:

(1) Lapho Ufuna Izimpawu Ezincane ze-Narrowband, Ivelu ye-RBW Kufanele Ibekwe Phansi Ngokungenzeka, Kungenjalo Isiginali Esizobhekiswa Kuyo Sizohlanganiswa Futhi Ayikwazi Ukuhlukaniswa, Futhi Singagwinywa Umsindo Wesithwebuli Futhi Singabonakali Ngokuphelele; Kepha Uma Inani Le-RBW Liphansi Kakhulu, Isikhathi Sokushanela Sizoba Side Kakhulu Futhi Amandla Wokuhlola Azothinteka;

(2) Uma Ubheka Ukuthi Ububanzi Bomkhawulo We-RB Eyodwa Ye-GSM Signal, i-PHS Signal Ne-TD-LTE Isondele Ku-200K, Namandla Okuhlola Sekukonke, Kunconywa Ukuthi i-RBW Yesithwebuli Ibekwe Ku-200KHz.

Isimiso Sokusethwa Kwebhande Le-Frequency Is:

(1) Ngokusebenzisana Kwesihlungi, Setha Isikali Se-Frequency Band Ku-LTE System Bandwidth Scale Yokuphenya Izimo Zokuthikanyezeka ze-In-Band, Njengokuthikanyezwa kwe-F-Band TDS In-Band, Ukuphazamiseka Kwesibili kwe-Harmonic, ne-DCS Intermodulation Interference. Kuyancomeka Ukuxhuma Isihambeli Esihambisanayo Se-Frequency Band Lapho Ushanela Imvamisa. Isibonelo, Uphenyo Lwe-F-Band Olubekiwe Lubekwe Ku-1880-1900MHz. Lapho Ishanela Imvamisa, Noma Yikuphi I-Port Of The Antenna Inganqanyulwa E-RRU, Ixhuma Isihlungi, Futhi Ixhume Isihlungi Lokukhipha Port Nge-Frequency Scanner;

(2) Shanela Amabhendi Wemvamisa Ephezulu Naphansi Asezingeni Eliphakeme Le-Target Frequency Band Ukuze Uphenye Ukuthi Kunemisebenzi Ehlukile Yesiginali Yezimpawu Ku-Sub-Bands Ehlukene. Isibonelo, Lapho Uphenya Ukuphazamiseka Kwe-F-Band, Ungasetha I-Sweep Frequency Band Scale 1805MHz-1920MHz, Futhi Phenya i-1805-1920MHz Ngokwehlukana. Ngokuya Kwisiginali Nokuqina Kuka-1830MHz, 1830-1850MHz, 1850-1880MHz, Nango-1900-1920MHz Frequency Bands, Phenya Amandla Esiginali E-DCS Ngokuya Ngokwe-Waveform Yokuphazanyiswa Ukusiza Ukunquma Ukuthi Kungaba Yini I-DCS Ekhohlisayo Nokuphazamiseka Okugcwele;

 

Ukuhlanganisa Izimo Zokuphazamiseka Kwangaphakathi Nebhendi Nezimo Zokuphazamiseka Kwangaphandle Kwesigaba Sezikhathi Eziningi Ezingaphezulu Nezingaphansi Ezinyathelweni Ezingenhla Ezimbili, Kungenzeka Ukuhlaziya Izisindo Ezingafani Zokuphazamiseka Esimeni Sezinxushunxushu Lapho Ukuphikiswa Okuningana Kuphakanyiswa khona.
