Kev piav qhia txog khoom
1. Cov Lus Qhia Txog Khoom
SA1300CCov khoom siv sab nraum zoov bi-directional trunk amplifier yog lub amplifier tshiab uas muaj txiaj ntsig zoo. Kev tsim qauv Circuit Court uas paub tab thiab zoo tshaj plaws, cov txheej txheem sab hauv uas tsim nyog thiab siv tau zoo, ua kom muaj txiaj ntsig ruaj khov thiab tsis muaj kev cuam tshuam. Nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim cov network loj lossis nruab nrab CATV bi-directional.
2. Cov yam ntxwv ntawm kev ua tau zoo
- Txoj kev mus tom ntej ua ntej theem txais yuav qhov tshiab tshaj plaws siab index imported qis suab nrov thawb-rub amplifier module lossis GaAs thawb-rub module, cov zis theem txais yuav qhov tshiab tshaj plaws siab index imported fais fab ob npaugyamplifier module lossis GaAs amplifier module. Tus lej nonlinear zoo thiab qib tso zis ruaj khov dua. Txoj kev rov qab los txais yuav qhov tshiab tshaj plaws siab index xa rov qab los ntawm txawv teb chaws. Qhov kev cuam tshuam tsawg thiab qhov sib piv ntawm lub teeb liab thiab suab nrov siab.
- Nws yooj yim dua rau kev debug vim yog lub lim dej duplex plug-in, lub tshuab sib npaug thiab attenuator ruaj khov (lossis kho tau), thiab cov chaw nres nkoj tshawb nrhiav online thiab tsim nyog.
- Cov khoom siv no tuaj yeem ua haujlwm tau ntev tsis tu ncua hauv qhov chaw tsis zoo sab nraum zoov. Vim yog lub tsev txhuas tsis muaj dej, muaj kev ntseeg siab rau kev hloov pauv hluav taws xob thiab lub kaw lus tiv thaiv xob laim.
- Lub plhaub txais yuav kev tsim qauv modular embedded; kev saib xyuas khoom siv, hloov pauv, thiab debugging yog qhov yooj yim.
3. Phau Ntawv Qhia Txog Kev Yuav Khoom
Thov paub meej tias: qhov zaus ntawm kev faib cov uplink thiab downlink ntawm cov kev taw qhia ob sab.
4. Cov Lus Qhia Tshwj Xeeb:
- Ua ntej siv cov khoom yuav tsum tau grounding txhim khu kev qha!
- Lub peev xwm siab tshaj plaws ntawm cov khoom yog 10A.
