Xaqiiqdii miyaad wax ka taqaanaa Scanners-ka Dijital ah?

Muuqaal ahaan Tijaabada Wadada Caadiga ah, Scanner-ka Dijital ah wuxuu run ahaantii ka tarjumayaa Deegaanka Biyo-la'aanta Aagga Imtixaanka. Waxaa Loogu Adeegsaday CW (Wave joogto ah) Tijaabinta Calaamadaha, Tijaabinta Shabakada Tijaabinta Wadada, iyo Iskuxirista Shabakada ee Nidaamyada Qaybinta Qolka.

Aynu Eegno Halbeegyada Iyo Mabaadi'da Caadiga Ah Ee Waqtiga Iyo Qeybta Aaladda Isbaarooleyda Dijital Ah Si Loo Wareeriyo Baaritaanka.

Halbeegyada Muhiimka ah ee Scanner-ka Dijital ah waxaa ka mid ah Dejiyeyaasha Dhexdhexaadiyaha Gudaha, RBW (Xallinta Baaxadda Xallinta) Dejinta, Nidaamka Cabbirka Joogtada, IWM.

Mabaadi'da Dejinta Dhexdhexaadiyaha RF Gudaha waa:

(1) Markay lagama maarmaanka u tahay Raadinta Calaamadaha Yar, Qiimaynta Qiyaasta waa in loo dhigaa sida ugu yar ee suuragalka ah, haddii kale Calaamadaha Bartilmaameedka la Raadinayo ayaa lagu liqi doonaa Buuqda Hoose ee Jaangooyaha Joogtada ah oo Lama Arki Karo;

(2) Markay lagama maarmaan tahay in la ogaado calaamado adag, Qiimaha imaatinka waa in sare loo qaadaa sida ugu macquulsan, hadii kale waxay sababi doontaa khalkhal aan toos ahayn oo wareega wareega ah, soo bandhig calaamadaha been abuurka ah, iyo xitaa dhaawaca muuqaalka;

 

Mabaadi'da Dejinta ee RBW waa:

(1) Markaad Raadinayso Calaamadaha Yar-yar ee Cidhiidhiga ah, Qiimaha RBW waa in loo dhigaa sida ugu yar ee suurtogalka ah, Haddii kale Calaamadaha Bartilmaameedka Raadinta waa la midoobi doonaa lamana kala duwanaan karo, oo xitaa waxaa liqaya Sawaxanka Sawirka oo gebi ahaanba aan la arki karin; Laakiin Haddii Haddii Qiimaha RBW uu aad u hooseeyo, Waqtiga xaaqintu wuu dheeraan doonaa oo awoodda tijaabada ayaa saameyn doonta;

(2) Markuu Tixgeliyey in Xadka ballaadhinta ee Hal RB oo ah GSM Signal, PHS Signal iyo TD-LTE uu kudhowyahay 200K, iyo Isugeynta Awooda Tijaabada, Waxaa lagugula talinayaa in RBW-ka Scannerka loo dhigo 200KHz.

Mabaadi'da Dejinta Baaxadda Joogtada ah waa:

(1) Iyadoo loo marayo Iskaashiga Sifeeyaha, U deji Miisaanka Jaangooyada Bandhiga Nidaamka LTE ee Baaxadda Baadhitaanka si loo baaro Xaaladaha Faro-gelinta Kooxaha, Sida F-Band TDS In-Band Faragelinta, Faragelinta GSM Second Harmonic, Iyo Faragelinta Dhexdhexaadinta DCS. Waxaa La Talin Ah In Lagu Xidho Filterka Joogtada Ah Ee Miiraha Markay Xaaqayso Jirka. Tusaale ahaan, F-Band Scarabling Baadhitaan ayaa loo dhigay 1880-1900MHz. Markaad Xaaqayso Mowjadda, Deked kasta oo anteeno ah ayaa lagaga goyn karaa RRU, isku xidhka shaandhada, iyo isku xidhka dekedda wax soo saar ee shaandhada iyo Mashiinka Mowjadaha;

(2) Xaaq Kooxaha Feejignaanta Sare iyo Kuwa Hoose ee Isku Xidha Kooxda Feejignaanta Bartilmaameedka ah si loo baaro in ay jiraan Shaqooyin Calaamado Kala Duwan oo ku Shaqeeya Qeybo Kala Duwan. Tusaale, Markaad Baadhitaan Ku Sameyneyso Faragelinta F-Band, Waxaad Dejin Kartaa Miisaanka Ballaaran ee Mowjadda Bandhigga 1805MHz-1920MHz, Oo Baaraa 1805-1920MHz Si gooni ah. Sida ku xusan Calaamadda iyo Cufnaanta 1830MHz, 1830-1850MHz, 1850-1880MHz, Iyo 1900-1920MHz Bands Frequency, Baadhitaan Astaamaha Awoodda ee DCS sida ku cad Faragelinta Waveform si ay uga caawiso go'aaminta in ay jiri karaan DCS faragalin iyo faragalin buuxda;

 

Isu geynta Xaaladaha Farogelinta Kooxda-Dhexdeeda iyo Xaaladda Faro-gelinta-ka-Baxsanaanta ee Mowjadaha Sare iyo Hoose ee isku Dhaw ee Labada Talaabo ee Sare, Waxaa Suuragal ah in lagu falanqeeyo Miisaanka Faragelinta ee Kala Duwan ee Muuqaalka Qalalaasaha ah ee Halkaas oo faragelinno badan lagu soo bandhigo.
