Sistimi ea maekerofounu e se nang mohala ea profeshenale ea UHF - phetiso ea kutloisiso e phahameng
Sistimi ena ya maekerofounu e se nang mohala ya UHF e sebedisa theknoloji e tswetseng pele ya ho kopanya maqhubu a PLL (Phase Locked Loop), e fanang ka dintlha tse 100 tsa maqhubu a fetolwang, e akaretsang mefuta e mengata ya maqhubu a 460-950MHz, e tshehetsa kamohelo ya dikanale tse pedi, le ho fihlela ditlhoko tsa disebediswa tse ngata bakeng sa tshebediso e le nngwe. Sistimi ena e na le bokgoni bo botle ba ho thibela tshitiso. Ka moralo wa ho lekanya antenna le mosebetsi wa "ho notlela lerata", e sireletsa ka katleho tshitiso ya RF ya tikoloho, e netefatsa bohloeki le botsitso ba letshwao, mme e loketse maemo a profeshenale a kang diketsahalo, dikopano le thuto.

Khokahano ea maqhubu a bohlale
Mosebetsi wa ho hokahanya ha infrared wa ho tobetsa hanngoe [IR], tobetsa ho hokahanya maqhubu a moamoheli ka bohona ho transmitter, ho tlosa modulation ya maqhubu a khathatsang ya letsoho le ho netefatsa tshebetso e sebetsang hantle le e nepahetseng.
Phetiso e phahameng ea botsitso
Ho nepahala ha maqhubu a phahameng haholo a ± 0.0005%, ho kopantsoe le taolo ea loop e koetsoeng ka mohato oa PLL, ho felisa mathata a ho kheloha ha maqhubu, ka ho kheloha ho hoholo ha maqhubu a ± 45KHz, ho netefatsa hore ha ho na tšitiso ea maqhubu kapa tieho molumong.
Sebaka se selelele ka botšepehi bo phahameng
Tikolohong e bulehileng, sebaka sa phetiso se ka fihla ho limithara tse 100. Yuniti ea maekerofouno e nang le tataiso e matla, hammoho le modulation ea FM, e na le sebaka sa karabelo ea maqhubu a 45Hz ~ 18KHz (± 3dB), ka ho sotha ho felletseng ha harmonic ha
