Ntawm cov txheej txheem tsim khoom ntawm cov khoom siv modulator, qee cov txheej txheem multiplexing tau siv. Ib tug ntawm lawv yog lub multiplexer. Ntawm ntau PBI modulator khoom, cov cuab yeej no muaj ntau yam zoo thiab nta.
1. Lub tshuab hluav taws xob hloov kho tau txais kev hloov pauv tam sim no niaj hnub no thiab yog tswj los ntawm ib lub tshuab microcomputer, uas ruaj khov thiab txhim khu kev qha.
2. Lub modulation Circuit Court ntawm txhua channel yog ywj siab kiag li, thiab channel configuration yog hloov tau yooj yim thiab yooj yim, thiab tus neeg siv yuav thov tau tej channel kev npaj uas tsis yog ib tug nyob ib sab zaus.
3. Lub teeb liab tso zis muaj zog. Noj cov 32-txoj kev modulator ua piv txwv, ib tug dual power multiplier module yog siv los tso tawm ib kab.
4. Cov khoom siv hluav taws xob muaj ntau qhov rov ua dua thiab tuaj yeem ua haujlwm tsis tu ncua thiab ruaj khov txhua xyoo.
5. Qhov cuam tshuam debugging ntawm cov khoom siv cable TV kis tau tus mob tau ua tiav ua ntej tawm hauv lub hoobkas. Nws yog dawb ntawm debugging ntawm qhov chaw. Nws tuaj yeem ua haujlwm tom qab txuas cov khoom siv hluav taws xob thiab nkag rau AV teeb liab. Nws tuaj yeem ntsia tau thiab tsim los ntawm cov tsis muaj kev tshaj lij.
6. Multi-channel modulator yog kev koom ua ke thiab ntsia, thiab cov qauv yog compact, thiab tsis tas yuav tsum muaj chav tshuab tshwj xeeb.
