Kev piav qhia
CT-SAW860 yog ib qho khoom siv tag nrho- lub xeev audio/video modulator uas muab cov video modulated andaural RF cab kuj tso zis rau ntawm ib tug ruaj channel ntawm 54MHz mus rau 860MHz.
Lub SAW Filtered Audio Video Modulator lees txais cov qauv polarity video ntawm 0.7-2.5 Vp-p qib los ntawm cov peev txheej video xws li satellite receiver, demodulator, TV camera, DVD player lossis video tape recorder.
Chav tsev muab cov yeeb yaj kiab zoo, xim, thiab cov cim suab ntawm ib qho channel uas tsis siv nyob rau hauv lub kaw lus kaw MATV, SMATV, lossis CATV system. Rau kev ua haujlwm yooj yim, txhua theem tswj tau nyob ntawm lub vaj huam sib luag pem hauv ntej.

SAW Filtered Audio Video Modulator yog dab tsi?
SAW Filtered Audio Video Modulator yog ib qho khoom siv feem ntau siv hauv analog TV systems rau kev tshaj tawm suab thiab video signals. Nws ntiav cov ntxaij lim dej Surface Acoustic Wave (SAW) kom meej meej thiab lim cov teeb liab modulated, kom ua raws li cov qauv tshwj xeeb thiab txo kev cuam tshuam.
SAW Filter ua haujlwm li cas hauv cov ntsiab lus no?
Lub Nto Acoustic Wave (SAW) lim yog ib qho khoom siv acoustic yoj uas lim thiab ua cov teeb liab hluav taws xob ntawm xov tooj cua zaus. Hauv qhov modulator no, nws pab kho cov yam ntxwv zaus ntawm lub suab - video teeb liab, xyuas kom nws nyob twj ywm nyob rau hauv cov zaus spectrum thiab txo kev cuam tshuam.
Lub hom phiaj ntawm SAW Filter hauv Audio Video Modulator yog dab tsi?
SAW lim nyob rau hauv lub modulator ua hauj lwm los tsim thiab lim cov teeb liab modulated. Nws pab ua kom tau raws li cov qauv zaus, tiv thaiv kev cuam tshuam nrog cov channel uas nyob ib sab, thiab txhim kho tag nrho qhov zoo ntawm lub suab sib kis- video teeb liab.
SAW Filtered Audio Video Modulator
SAW (Surface Acoustic Wave) Lim Suab Video Modulator yog ib qho cuab yeej siv hauv analog TV systems rau tshaj tawm suab thiab video signals.
