Limithara tsa motlakase tsa RF li ka aroloa ka limithara tsa motlakase tsa RF tse thehiloeng mochesong, li-detectors tse nang le diode-powered, absorption RF power met, le metres-through. Metara ea matla a RF e thehiloeng mochesong ke khetho e ntle ha o etsa mesebetsi e kopaneng ea ho metha, 'me sesebelisoa se nang le matla a diode ke khetho ha ho hlokahala hore ho baloe boemo ba motheo kapa tlhaho ea nakoana. Ehlile, o boetse o hloka ho ela hloko hore na meter ea hau ea motlakase ea RF e loketse ho rekota metriki e ikhethang joalo ka matla a tloaelehileng, matla a ho otla kapa matla a holimo a enfelopo. Le ha meter ea matla ea RF e monya e loketse ho fumana lintlha tsa laboratori tse nepahetseng haholo, meter ea motlakase ea RF e loketse mesebetsi ea masimong.

 

#2 Litaba tsa Marang-rang bakeng sa ho Nepaha

 

Ho bohlokoa ho khetha sebaka se nepahetseng sa maqhubu. Maqhubu a manyane a tla le phoso e kholoanyane, mohlala, haeba o fana ka transmitter ea FM e nang le maqhubu ho tloha ho 88 ho isa ho 108Mhz, meter ea matla ea 85-110Mhz RF ke khetho ea hau e ntle ka ho fetisisa.

 

Haeba u tloaetse ho sebelisa meter ea matla ea RF ea 1-200Mhz ho laela mochini o fetisang molaetsa oa FM, phoso ea eona e tla ba kholo ho feta meter ea motlakase ea RF e nang le mefuta e nyane ea freq. E ka baka mathata a kang lintlha tse sa nepahalang tsa phepelo ea matla a transmitter le antenna VSWR.

 

#3 Etsa hore Commissiong e be bonolo haholoanyane ka APP Monitoring

 

Ho khetha meter ea motlakase ea RF e nang le tlhahlobo ea APP ho ka u bolokela nako. Mofuta ona oa meter ea matla a RF o fana ka ponts'o ea dijithale le ts'ebetso ea ho rekota nako. Ho tsepamisa maikutlo tabeng ea ho laela transmitter le antenna ho setse ho etsoa, ​​​​ha ho sa na lebaka la ho rekota VSWR le ho fetisa lintlha tsa matla bukeng! Ua tseba hore na sena se bolela eng mosebetsing oa hau.

 

#4 Le ka mohla u se ke ua Tlohela Boleng ba Sehlahisoa ka Morao. 

 

Metara ea matla a RF e nang le boleng bo holimo hangata e na le nako e telele ea ts'ebeletso - e boetse e netefatsa ho nepahala ha ts'ebetso ea hau. Ho feta moo, moralo o thata o fana ka ts'ireletso e kholoanyane ea ho lokolla limithara tsa motlakase ho tloha maqhubung a tšebetso le lipalangoang. Kahoo, kamehla u be hlokolosi ka boleng pele u kenya odara ea meter ea motlakase ea RF. 

 

#5 Freq Selection kapa Freq Fixed Mofuta

 

Ho bohlokoa ho elelloa hore limithara tsa motlakase tsa RF li ka khetha khafetsa kapa li tsitsitse, phapang e kholo lipakeng tsa tse peli ke ho nepahala le theko.

 

Mohlala, meter ea motlakase ea RF e nkehang ho tsoa ho Nonyana e ka fihlela litlhoko tsa liteko tsa maqhubu a fapaneng (joalo ka 450kHz-2.7GHz kapa 50-100MHz, joalo-joalo) le matla (joalo ka 100mW-10kW) ka ho bapisa matla a plug-in. dikarolo.

 

Leha ho le joalo, theko ea eona e ka fihla ho liranta tse likete. 

 

Bakeng sa baphatlalatsi ba bangata, theko e khaphatsehang ea thekiso, lebelo la maqhubu, le mefuta ea motlakase le tsona ha li hlokahale, re sa re liphetho tsa liteko li ka ba le liphapang tse kholo (leha ho thoe ho nepahala ke ± 5%).

 

Ha ho bapisoa le mefuta e mengata ea maqhubu le mefuta ea matla a pele, meter ea motlakase ea RF e khethang khafetsa e na le tlhahlobo e nepahetseng ea sebaka se holimo, 'me hangata e theko e tlase. 

 

Mofuta ona oa meter ea motlakase oa RF o ikhethile E sebelisoa ho lekola phallo ea matla a RF le boleng ba VSWR ba sehlopha sa maqhubu a FM, e leng eona e lekaneng ho fihlela tlhahlobo ea sistimi ea phetisetso ea liteishene tsa radio tsa FM tse matla a tlase.

 

Mabapi le FMUSER

 

FMUSER ke morekisi ea ka sehloohong oa lefats'e oa litharollo tsa khaso tse theko e tlaase. Ho tloha 2004, re atlehile ho fana ka litharollo tse likete tse tšepahalang tsa li-turnkey bakeng sa AM, FM, le liteishene tsa TV linaheng tse 'maloa ho pota lefatše, ho kenyeletsoa liphutheloana tse felletseng, tataiso ea ho kenya tse hole / sebakeng, ts'ebeletso e tšepahalang ea kamora thekiso, le tse ling.

 

 

Feme ea rona ea tlhahiso e netefatsa ts'ebetso ea maemo a holimo ho sesebelisoa se seng le se seng mme ho fihlela joale e file seteishene sa seea-le-moea sa moreki oa FMUSER matla a macha.

 

"Re leka ka hohle ho netefatsa boiphihlelo ba hau, ona ke thomo ea FMUSER"
