Iphaneli engaphambili
1. Uhlengahlengiso lwenqanaba lemveliso ye-RF—Iqhosha, inqanaba lemveliso ye-RF ehlengahlengiswayo
2. Uhlengahlengiso lomlinganiselo we-AV—Iqhosha lilungisa imveliso yomlinganiselo we-A / V
3. uhlengahlengiso lwevolumu—Iqhosha lokulungisa ubungakanani bevolumu yemveliso
4. Uhlengahlengiso lokukhanya—Iqhosha lokulungisa ukukhanya komfanekiso ophumayo
Iphaneli engasemva
A. Izibuko lovavanyo lwesiphumo: Izibuko lovavanyo lwesiphumo sevidiyo, -20dB
B. Isiphumo se-RF: Imodyuli ye-Multiplexer ilungisiwe, emva kokuxuba isiphumo se-RF
C. Ulawulo lwemveliso ye-RF: Iqhosha, inqanaba lemveliso ye-RF ehlengahlengiswayo
D. Ukuphuma kwe-Power cascade
Ukubeka ii-modulators ezininzi kwindawo enye, ungasusa i-output ukuya kwenye i-power modulator ukunciphisa ukusebenza kwe-outlet yombane; lumka ungasusi i-outlet engaphezulu kwe-5 ukuze uphephe umbane ogqithisileyo.
E. Ukufaka Amandla: I-AC 220V 50Hz/110V 60Hz
