Nidaamyada Imtixaanka Awoodda Sare ee BroadBand RF 75 Ohms Joojinta
Joojinta 75 ohm
Joojinta 75 ohm waa joojin iska caabin caadi ah oo inta badan loo isticmaalo tijaabinta iyo cabbirida qalabka sida koronto-dhaliyeyaasha, cod-weyneyaasha, nidaamyada RF, telefishinnada, iwm. ee wareegyada.
Waxay leedahay sifooyinka soo socda:
1.A 75 ohm Joojinta waxay yaraynaysaa muujinta calaamadaha iyo luminta, waxay wanaajisaa gudbinta calaamadaha, sidaas awgeed waxay hagaajinaysaa xasilloonida nidaamka iyo kalsoonida.
2.The 75 ohm Joojinta waa heer aad loo isticmaalo joojinta joojinta ee warshadaha isgaarsiinta, kaas oo la kulma Heerarka Shaybaarka Isgaarsiinta Federaalka (NIST) oo ay fududahay in loo isticmaalo shaqada dhabta ah.
3. Inta lagu jiro habka cabbirka iyo tijaabinta, 75 ohm Joojinta waxay ka ilaalin kartaa qalabka isha korantada xad dhaafka ah ama dhaawaca xad dhaafka ah, hubinta badbaadada qalabka tijaabada iyo qalabka la tijaabiyay.
4. Joojinta 75 ohm waxay taageeri kartaa soosaarka tamarta sare waxaana lagu dabaqi karaa nidaamyada RF ee u baahan awood sare.
5.A 75 ohm Joojinta waxay ku siin kartaa xannibaadda joojinta saxda ah ee saxda ah ee cabbirka saxda ah ee xuduudaha sifada wareegga, taasoo ka dhigaysa natiijooyinka imtixaanka mid sax ah oo la isku halayn karo.
Waxay leedahay shaqooyinka soo socda:
1.A 75 ohm Joojinta waxaa loo isticmaali karaa in lagu tijaabiyo awoodda wax soo saarka, sifooyinka jawaabta soo noqnoqda, iyo si loo xaqiijiyo waxqabadka guud ee wareegga.
2.A 75 ohm Joojinta waxaa loo isticmaali karaa in lagu wanaajiyo mowjadda mawjada, yaraynta muujinta calaamadaha iyo luminta, kor u qaadida gudbinta calaamadaha, iyo hagaajinta xasilloonida nidaamka iyo isku halaynta.
3.A 75 ohm Joojinta waxay u adeegi kartaa sida dekedda wax-soo-saarka calaamadaha ee koronto-dhaliyeyaasha calaamadaha iyo kor-u-qaadayaasha awoodda, taas oo awood u siinaysa calaamadaha in loo soo saaro qaybaha kale ee nidaamka ujeedooyinka tijaabinta iyo cabbirka.
4.A 75 ohm Joojinta waxay ka ilaalin kartaa qaybaha kale ee wareegga korantada iyo ka badan Joojinta, yaraynta khatarta qalabka iyo cilladaha.
QualwaveWaxay siisaa kala duwanaansho kala duwan oo sax ah oo sarreeya iyo koronto badan oo coaxial 75 Ohms Joojinta waxay daboolaysaa inta jeer ee DC ~ 3GHz. Joojinta noocyada kala duwan si loo daboolo baahiyaha macaamiisha
