1. Yog, Cov zauv ntau yam yuav tau hloov ntawm 170Mhz (Zoo ntawm 220Mhz) rau 860Mhz. Li ntawd, nws yuav ua hauj lwm zoo ntawm 260Mhz qhab.
2. Qhov frequency yuav tsum tau hloov mus rau tib yam rau cov transmitter thiab receiver. ua kom muaj kev ua kom muaj, Lub hwj huam Amplifier thiab antenna frequency yuav tsum hloov tib zaus. (Koj yuav tau mus yuav ib lub hwj huam amplifier thiab antenna rau lub transmitter thiab receiver kom tau raws li koj hloov zaus).
3. Yuav kom cov rhiab ntawm transmitting thiab tau txais, Cov frequency bandwidth feem ntau ua nqaim heev (qhov chaw ±15Mhz, Li ntawd, bandwidth yuav tsum tau 30Mhz). Lub hwj huam amplifier ntawm tus transmitter thiab cov frequency ntawm tus antenna yog tshwj xeeb tshaj yog customized raws li tus frequency koj xav tau.
4. Nws zoo tshaj plaws thaum koj muab ib qho kev txiav txim, thov qhia kuv seb koj ua hauj lwm zoo li cas uas koj xav tau. Peb engineers yuav hloov lub frequency ntawm tus transmitter thiab receiver, thiab kuj hloov cov PA thiab kev lis kev cai antenna raws li no zaus ntau yam Xyuas kom meej tias qhov zoo tshaj plaws thiab txhawb qhov ntev transmission nyob deb li cas.
5. Tus default frequency yog 590Mhz, Nrog 30Mhz (+/-15Mhz), Koj yuav hloov nws tsis modifying lub hwj huam Amplifier thiab antenna. Piv txwv, 578Mhz, 584Mhz, 590Mhz, 596Mhz, thiab 602Mhz.
6. Yog hais tias koj yuav tsum tau hloov tus transmitter frequency thiab bandwidth, Koj xav tau ib tug tshwj xeeb ntawm lub parameter configure board, thov saib daim duab hauv qab no, Nws tsi muaj ib tug default accessory, Thov yuav nws ntawm tus nqi ntxiv los yog hu rau peb ua ntej yuav txiav txim.

Yog, Nws txhawb xa cov yees duab thiab UART cov ntaub ntawv Ntawm tus transmitter thiab receiver.
Thaum nws yog ib txoj kev transmission, Li ntawd, nws yuav tsis xa tus tswj command ntawm tus receiver rau lub transmitter.

Yog hais tias koj yuav tsum xa tswj commands los yog lwm cov ntaub ntawv los ntawm tus receiver los tswj lwm yam li koob yees duab los yog drones ntawm tus transmitter, Koj yuav ntxiv ib txheej pheej yig transmission khoom, hu rau peb, thiab peb yuav customize nws rau koj.

Thov xyuas cov UART txhais ntawm tus transmitter thiab receiver ntawm qhov txuas hauv qab no. Thov qhia rau kuv yog hais tias koj xav kom muaj ib cov hlau lead cable. (tsis muaj)

Tus transmitter default Power Amplifier yog 2 Watts, Li ntawd, nws yuav txhawb tau 30 KM ntawm line-of-sight.

Cov duab hauv qab no yog peb kuaj nyob deb li cas ntawm lub roob rau lub seaside.

Yog hais tias koj xav transmit ntau yam ntev, Koj yuav ua tau kom lub hwj huam amplifier. Ntxiv rau ib watt thiab ob watts, Peb kuj ua tau 5 watts, 10 watts, thiab 20 watts rau koj xaiv. Loj amplifiers kuj yuav tsum tau loj roj teeb thiab tam sim no txhawb.

Rau 20W PA, Lub hwj huam mov yuav tsum muaj 24.28V. Tsuas yog thaum kawg xwb 28 volts yuav lub hwj huam amplifier cuag qhov zoo tshaj plaws ua hauj lwm.

Peb engineer yuav hloov cov frequency rau 300Mhz ntawm tus default 590Mhz, Tus antenna, Thiab PA hauv lub warehouse yog 590Mhz, 300Mhz xav tau ob lub lis piam rau customize, Li ntawd, tus me nyuam lub sij hawm yuav tsum tau ntev dua peb default 590Mhz.

Lub default daim ntawv qhia txog teev

1. SD Transmitter ( PA 0.5W, 1W, 2W, 5W, 10W, 20W, 50W xaiv raws li koj qhov kev txiav txim thov)
2. SD Transmitter antenna
3. HDMI CVBS tso zis receiver nrog parameter tswj zaub mov thiab me me screen
4. 0.8-meter receiver antenna 1 pcs. (Muaj ob hom installing los yog kho cov antenna: 1. magnetic sucker puag antenna, 2. Default U-hom clamp FRP fiberglass antenna )
5. Yeem, parameter configuration board rau lub wireless yees duab transmitter.

(Yog hais tias koj xav tau ib tug magnetic sucker puag antenna, Tus qhia los yog carrier xav tias cov khoom magnetic yuav cuam tshuam nrog lawv lub dav hlau kev ruaj ntseg, Li ntawd, tus nqi shipping yog ntau tshaj ib U-hom clamp antenna. )

Tus default daim ntawv qhia txog teev pob dimension

1. 84*21*12CM
2. Tag nrho luj 4.5KG
3. Yog hais tias koj xaiv tshaj 100cm antenna thiab magnetic sucker puag antenna, Ib txhia freight forwarders yuav them nqi ntxiv, Xws li cov nqi ntxiv thiab cov nqi ntxiv rau cov khoom magnetic khoom.

1. Tus transmitter parameter configures board yog txawv ntawm ib tus receiver. Qhov ruaj rau lub parameter configure board yog txawv ntawm tus transmitter thiab receiver, Lawv tsis tau siv interchangeably.
2. Tus transmitter parameter configures board yuav kho tau lub teeb liab attenuation rau lub transmitter. Ib 0.3db yuav txo tau qhov 0.5W PA.

Lus nug: Tej zaum yuav hloov lub hwj huam outpout (paj thoob ntiaj teb 0,5 w, 1 w, 2 w) Ntawm lub rooj tswjhwm saib cov configuration?

1. Teb saum toj no, Koj yuav kho tau cov zis tso zis los teev cov parameters ntawm ATTEN los ntawm cov parameter configuration board tool rau lub transmitter. (Qhov no tsis muaj xws li cov pob default pob, Koj yuav tsum qhia rau koj paub tias koj xav kom muaj cov cuab yeej no thaum koj txiav txim)
2. Yog hais tias koj yuav 2W PA, Ces koj yuav teem nws 0.5W, 1W, Tiam sis yuav tsis hloov nws mus rau 5W.
3. Peb kuj yuav ua rau 5W, 10W, 20W, thiab 50W yog hais tias koj xav tau kev pab txhawb mus sij hawm ntev.

Tsis muaj.

No wireless yees duab transmitter tsuas txhawb CVBS koob yees duab los yog yees duab input, Lwm hom yees duab yees duab xav tau ib lub thawv converter ntxiv.

Tsis muaj. Nws yog COFDM (DVB-T) Tej txuj ci tshiab.

Li ntawd, cov COFDM frequency ntau yam yog 170-860Mhz. Nws yuav txhawb tau kev them nyiaj yug me nyuam 477, 610, 675, 724, 816Mhz, tab sis yuav tsis txhawb 970, 1180, 1230 Mhz.

Peb tus qauv tshwj xeeb transmitter yuav txhawb tag nrho cov saum toj no ntau yam, Tiam sis tus receiver yuav tsum siv cov downconverter thaiv.

Thiaj li yuav cia peb wireless transmitting lawv txhawb ib wider ntau yam thiab zoo teeb liab lub zog, Peb feem ntau teem cov kev khiav hauj lwm frequency rau ib kis (170£860Mhz), Thiab nws txaus siab ntau yam yog tsuas plus los yog rho tawm 15Mhz. Piv txwv, Qhov chaw frequency yog 590Mhz, max kev them nyiaj yug frequency ntau yam yuav tsum tau 575Mhz$605Mhz, Cov PA thiab antenna yog tshwj xeeb tshaj yog customized raws li qhov chaw no zaus.

Yog
