1. Yog, Qhov ntau zaus tuaj yeem hloov pauv ntawm 170Mhz (zoo los ntawm 220Mhz) rau 860mhz. Yog li nws tuaj yeem ua haujlwm zoo ntawm 260Mhz band.
2. Qhov zaus yuav tsum tau hloov mus rau tib yam ntawm lub transmitter thiab receiver. Yog vim li cas, Lub hwj chim Amplifier thiab kav hlau txais xov zaus yuav tsum hloov kho tib zaus. (Koj yuav tsum tau yuav lub hwj chim amplifier thiab kav hlau txais xov rau lub transmitter thiab receiver kom tau raws li koj qhov kev hloov zaus).
3. Txhawm rau txhim kho qhov rhiab heev ntawm kev xa tawm thiab tau txais, qhov zaus bandwidth feem ntau ua nqaim heev (nruab nrab zaus ±15Mhz, yog li bandwidth yuav tsum yog 30Mhz). Lub hwj chim amplifier ntawm lub transmitter thiab zaus ntawm lub kav hlau txais xov yog tshwj xeeb customized raws li qhov zaus koj xav tau.
4. Nws yog qhov zoo tshaj thaum koj tso qhov kev txiav txim, thov qhia rau kuv seb koj xav tau dab tsi ua haujlwm zaus. Peb cov engineers yuav hloov qhov zaus ntawm lub transmitter thiab receiver, thiab kuj hloov kho PA thiab kev cai kav hlau txais xov raws li qhov ntau zaus no los xyuas kom meej qhov zoo tshaj plaws rhiab heev thiab txhawb qhov ntev tshaj qhov sib kis.
5. Lub neej ntawd zaus yog 590Mhz, Nrog 30Mhz (+/-15Mhz), koj tuaj yeem hloov nws yam tsis tau hloov kho lub hwj chim Amplifier thiab kav hlau txais xov. Piv txwv li, 578Mhz, 584Mhz, 590Mhz, 596Mhz, thiab 602Mhz.
6. Yog hais tias koj yuav tsum tau hloov lub transmitter zaus thiab bandwidth, koj xav tau ib lub cuab yeej tshwj xeeb ntawm parameter configure board, thov saib daim duab hauv qab no, nws tsis yog ib tug default accessory, thov yuav nws ntawm tus nqi ntxiv lossis tiv tauj peb ua ntej xaj.

Yog, nws txhawb xa cov video thiab UART cov ntaub ntawv los ntawm transmitter thiab receiver.
Raws li nws yog ib txoj kev kis tau tus mob, yog li nws tsis tuaj yeem xa cov lus txib los ntawm lub receiver mus rau lub transmitter.

Yog tias koj xav tau xa cov lus txib lossis lwm cov ntaub ntawv los ntawm lub receiver los tswj lwm yam khoom siv xws li lub koob yees duab lossis drones ntawm lub transmitter., koj tuaj yeem ntxiv cov khoom pheej yig digital kis tau tus mob, hu rau peb, thiab peb tuaj yeem kho nws rau koj.

Thov xyuas UART txhais ntawm lub transmitter thiab receiver ntawm qhov txuas hauv qab no. Thov qhia rau kuv yog tias koj xav tau cov kab hlau lead. (default yog tsis muaj)

Lub transmitter default Power Amplifier yog 2 Watts, yog li nws tuaj yeem txhawb nqa 30 KM ntawm kab ntawm qhov pom.

Daim duab hauv qab no yog peb qhov kev sim deb ntawm lub roob mus rau ntug hiav txwv.

Yog tias koj xav xa cov kab ntev dua, koj tuaj yeem nce lub zog amplifier. Ntxiv rau ib watt thiab ob watts, peb kuj tuaj yeem ua tau 5 watts, 10 watts, thiab 20 watts rau koj xaiv. Cov amplifiers loj dua kuj xav tau cov roj teeb loj dua thiab kev txhawb nqa tam sim no.

Rau 20W PA, Lub hwj chim yuav tsum yog 24 ~ 28V. Tsuas yog ntawm 28 volts tuaj yeem ua lub zog amplifier ua tiav qhov kev ua haujlwm zoo tshaj plaws.

Peb tus engineer tuaj yeem hloov qhov zaus mus rau 300Mhz los ntawm lub neej ntawd 590Mhz, Lub kav hlau txais xov, thiab PA hauv warehouse yog 590Mhz, 300Mhz xav tau ob lub lis piam los kho, yog li lub sijhawm xa khoom xav tau ntev dua li peb lub neej ntawd 590Mhz.

Cov txheej txheem tag nrho

1. SD Transmitter ( PA 0.5W, 1W, 2W, 5W, 10W, 20W, 50W xaiv tau raws li koj qhov kev thov)
2. SD Transmitter kav hlau txais xov
3. HDMI CVBS tso zis receiver nrog parameter tswj zaub mov thiab lub vijtsam me
4. 0.8-meter receiver kav hlau txais xov 1 pcs. (Muaj ob hom kev txhim kho lossis kho lub kav hlau txais xov: 1. magnetic sucker puag kav hlau txais xov, 2. default U-type clamp FRP fiberglass kav hlau txais xov )
5. yeem, parameter configuration board rau lub wireless video transmitter.

(Yog hais tias koj xav tau ib tug magnetic sucker puag kav hlau txais xov, tus nthuav qhia lossis cov neeg nqa khoom xav tias cov khoom sib nqus yuav cuam tshuam rau lawv lub dav hlau kev nyab xeeb, yog li tus nqi thauj khoom yog siab dua li U-hom clamp kav hlau txais xov. )

Lub default tag nrho set pob dimension

1. 84*21*12CM
2. Qhov hnyav tag nrho 4.5KG
3. Yog tias koj xaiv tshaj 100cm kav hlau txais xov thiab sib nqus nqus lub hauv paus kav hlau txais xov, Qee tus neeg xa khoom thauj khoom yuav them tus nqi ntxiv, xws li cov nqi ncua ntev thiab cov nqi ntxiv rau cov khoom sib nqus muaj zog.

1. Lub transmitter parameter configures board yog txawv los ntawm ib tug nyob rau hauv lub receiver. Lub firmware ntawm lub parameter configure board txawv ntawm lub transmitter thiab receiver, lawv tsis tuaj yeem siv sib hloov.
2. Lub transmitter parameter configures board tuaj yeem kho lub teeb liab attenuation ntawm lub transmitter. Ib 0.3db yuav txo qhov 0.5W PA.

Lo lus nug: Nws puas tuaj yeem hloov lub zog tawm (internal PA 0,5 w, 1 w, 2 w) ntawm lub rooj tsavxwm configuration?

1. Raws li teb saum toj no, koj tuaj yeem kho lub zog tso zis los ntawm kev teeb tsa qhov tsis muaj ntawm ATTEN los ntawm qhov ntsuas qhov ntsuas qhov ntsuas lub cuab yeej ntawm lub transmitter.. (Cov cuab yeej no tsis suav nrog lub neej ntawd pob, koj yuav tsum tau ceeb toom tias koj xav kom muaj cov cuab yeej no thaum koj xaj)
2. Yog tias koj yuav 2W PA, ces koj tuaj yeem teem nws 0.5W, 1W, tab sis tsis tuaj yeem hloov mus rau 5W.
3. Peb kuj tuaj yeem ua rau 5W, 10W, 20W, thiab 50W yog tias koj xav tau kev txhawb nqa ntev.

tsis.

Lub wireless video transmitter no tsuas yog txhawb nqa CVBS lub koob yees duab lossis yees duab tawm tswv yim, lwm hom yees duab yees xav tau ib lub thawv converter ntxiv.

tsis. Nws yog COFDM (DVB-T) technology.

Yog li COFDM zaus ntau yog 170-860Mhz. Nws tuaj yeem txhawb nqa 477, 610, 675, 724, 816Mhz, tab sis tsis tuaj yeem txhawb nqa 970, 1180, 1230 Mhz.

Peb tus qauv tshwj xeeb transmitter tuaj yeem txhawb nqa txhua qhov saum toj no, tab sis tus txais yuav tsum tau siv lub downconverter thaiv.

Yuav kom tso cai rau peb lub wireless kis tau tus mob los txhawb ntau qhov dav thiab zoo dua lub teeb liab zog, peb feem ntau teeb tsa qhov kev khiav hauj lwm zaus mus rau ib qho chaw (170~ 860Mhz), thiab nws cov kev txhawb nqa tsuas yog ntxiv lossis rho tawm 15Mhz. Piv txwv li, Qhov nruab nrab zaus yog 590Mhz, max txhawb ntau zaus yuav tsum yog 575Mhz ~ 605Mhz, PA thiab kav hlau txais xov tshwj xeeb yog kho raws li qhov chaw nruab nrab no.

Yog
