Ikizamini cya RF ni iki

1 testing Ikizamini cya RF ni iki

Radio Frequency, mubisanzwe mu magambo ahinnye nka RF.Ikizamini cya radiyo ni radiyo yumurongo wa radiyo, ni impfunyapfunyo yumurongo mwinshi uhinduranya amashanyarazi ya electroniki.Yerekana amashanyarazi ya electronique ishobora gukwirakwira mu kirere, hamwe n'umurongo uri hagati ya 300KHz na 110GHz.Iradiyo yumurongo, mu magambo ahinnye nka RF, ni amagambo ahinnye yumurongo mwinshi uhinduranya amashanyarazi ya electronique.Inshuro zimpinduka zitarenze inshuro 1000 kumasegonda byitwa umuyoboro muke, naho inshuro zirenga 10000 byitwa umuyoboro mwinshi.Iradiyo ni ubu bwoko bwumuvuduko mwinshi.

Ikwirakwizwa rya Frequency irahari hose, yaba WI-FI, Bluetooth, GPS, NFC (itumanaho rya hafi rya terefone), nibindi, byose bisaba kohereza inshuro.Muri iki gihe, tekinoroji ya radiyo ikoreshwa cyane mu rwego rwo gutumanaho bidafite umugozi, nka RFID, itumanaho rya sitasiyo, itumanaho rya satellite, n'ibindi.

Muri sisitemu yo gutumanaho idafite umugozi, RF imbere-imbaraga zongera imbaraga ni ikintu cyingenzi.Igikorwa cyacyo nyamukuru nukwongerera imbaraga imbaraga nke no kubona ingufu za RF zisohoka.Ibimenyetso bitagira umuyaga bifite uburambe bugaragara mukirere.Kugirango ukomeze serivisi nziza yitumanaho itumanaho, birakenewe ko twongerera ibimenyetso byahinduwe mubunini buhagije kandi tukabyohereza muri antenne.Nibyingenzi bya sisitemu yitumanaho ridafite insinga kandi igena ubuziranenge bwa sisitemu yitumanaho.

2 methods Uburyo bwo gupima RF

1. Huza amashanyarazi agabanye ukoresheje umugozi wa RF ukurikije igishushanyo cyavuzwe haruguru, hanyuma upime igihombo cya 5515C kuri EUT na EUT kuri ecran ya ecran ukoresheje isoko yerekana ibimenyetso na ecran, hanyuma wandike agaciro k'igihombo.
2. Nyuma yo gupima igihombo, huza EUT, E5515C, na spectrograph kumashanyarazi ukurikije igishushanyo, hanyuma uhuze iherezo ryigabanywa ryamashanyarazi hamwe no kwiyegereza cyane kuri ecran.
3. Hindura indishyi zumubare wumurongo nigihombo cyinzira kuri E5515C, hanyuma ushireho E5515C ukurikije ibipimo biri mumeza ikurikira.
4. Shiraho ihamagarwa ryo guhamagara hagati ya EUT na E5515C, hanyuma uhindure ibipimo bya E5515C kuburyo bwo kugenzura ingufu za bits zose kugirango bishoboke EUT gusohora imbaraga nyinshi.
5. Shiraho indishyi zo gutakaza inzira kuri ecran, hanyuma ugerageze inzererezi zakozwe ukurikije igice cyinshyi mumeza akurikira.Imbaraga zimpanuka za buri gice cyibipimo byapimwe zigomba kuba munsi yumupaka ugaragara kumeza ikurikira, kandi amakuru yapimwe agomba kwandikwa.
6. Hanyuma usubize ibipimo bya E5515C ukurikije imbonerahamwe ikurikira.
7. Shiraho ihuriro rishya ryo guhamagara hagati ya EUT na E5515C, hanyuma ushyireho ibipimo bya E5515C kugirango uhindure uburyo bwo kugenzura ingufu za 0 na 1.
8. Ukurikije imbonerahamwe ikurikira, ongera usubize ecran hanyuma ugerageze inzira yayobowe ukurikije igice cyinshi.Imbaraga zo hejuru ya buri gice cyapimwe zigomba kuba munsi yumupaka ugaragara kumeza ikurikira, kandi amakuru yapimwe agomba kwandikwa.

3 ipment Ibikoresho bisabwa mugupima RF

1. Kubikoresho bya RF bidapakiwe, sitasiyo ya probe ikoreshwa muguhuza, nibikoresho bifatika nka spekitrograph, isesengura rya neti ya vector, metero z'amashanyarazi, ibyuma bitanga ibimenyetso, oscilloscopes, nibindi bikoreshwa mugupima ibipimo bihuye.
2. Ibipaki bipfunyitse birashobora kugeragezwa hamwe nibikoresho, kandi inshuti zinganda zemerewe kuvugana.
