zaus harmonics

Hauv daim video saum toj no, sab laug yog peb FDD ob zaus COFDM transceiver module. Nyob rau hauv nruab nrab ntawm lub thawv hlau, muaj cov lim. Hauv video, peb yuav qhia koj qhov kev sim ntawm COFDM Video transmitter tso zis nrog cov ntxaij lim dej thiab tsis muaj lim.

Tam sim no Nws txuas ncaj qha rau lub kav hlau txais xov yam tsis muaj lim. Peb yuav pom qhov zaus harmonics tsim los ntawm lub transmitter.

Hauv video, lub siab tshaj plaws nthwv dej yog tam sim no kis zaus.
Qhov thib ob siab tshaj yog qhov thib ob harmonic, Qhov thib peb siab tshaj yog qhov thib peb harmonic, thiab qhov qis tshaj plaws yog qhov thib plaub harmonic. Tsis muaj ntau zaus harmonics tom qab no.

Nws tuaj yeem pom los ntawm cov cuab yeej ntsuas tam sim no tias yog tsis muaj lim, lub transmitter yuav tsim ntau zaus harmonics. Harmonics tshwm sim ntawm zaus 2 sij hawm, 3 sij hawm, thiab 4 lub sij hawm zaus. Frequency harmonics tuaj yeem cuam tshuam nrog lwm yam khoom siv.

Tam sim no cia saib ntxiv cov lim rau cov zis ntawm lub transmitter kom pom tias tseem muaj cov zaus sib haum xeeb.

Txuas lub lim ntawm lub transmitter thiab kav hlau txais xov. Qhov no yog 340Mhz wavepass lim. Ntawm cov zaus ntawm 330Mhz thiab 350Mhz cov cim tuaj yeem dhau mus, thiab lwm yam teeb liab raug thaiv. Hauv peb 1886 dual-frequency video transceiver, koj tuaj yeem xaiv ob zaus, ib qho rau uplink thiab ib qho rau downlink.

Kev xa thiab tau txais yog ua nyob rau hauv ob zaus, uas ua rau kom tus nqi sib kis thiab kev cuam tshuam kev cuam tshuam.

Tam sim no lub lim yog txuas los ntawm lub transmitter mus rau lub kav hlau txais xov. Tam sim no tsis muaj zaus harmonics ntawm qhov screen. Tsuas yog cov zaus kis tau tus mob, tag nrho lwm cov clutter tau lim tawm.

Tam sim no koj paub lub luag haujlwm tseem ceeb ntawm cov ntxaij lim dej. Yog tias koj xav tau kho lub COFDM transmitter, PA, los yog lim, thov hu rau peb rau kev daws teeb meem dawb thiab hais lus. ib ivcan.com/contact
