Imikorere
Igishushanyo 1. Igitekerezo cya karwi
Igishushanyo cya 2. Igisekuru cya Pulse
Igishushanyo cya 3. Modulator Max imbaraga
Igishushanyo cya 4. Modutor Imbaraga ntarengwa
Ikigereranyo cya Maxim DC
Muri ubu bushakashatsi, nta bimenyetso bya RF byakoreshwaga muri sisitemu. DC idasanzwe yarapimwe.
1. Ishusho 5 yerekana imbaraga za optique yo gusohoka, mugihe modutor igenzurwa na peak ingingo. Irerekana 3.71dbm mu gishushanyo.
2. Irerekana -46.73DBM mu gishushanyo. Mubushakashatsi nyabwo, agaciro kiratandukanye hafi -47DBM; na -46.73 ni agaciro gahamye.
3. Kubwibyo, igipimo cya DC gihamye cyapimwe ni 50.4DB.
Ibisabwa kugirango uzengure hejuru
1. Modulator ya sisitemu igomba kuba ifite igipimo cyo kuzimangana. Kuranga Modutor Modulator ihitamo igipimo ntarengwa cyo kuzimangana gishobora kugerwaho.
2. Ihuriro rya Modulator ryinjiza urumuri ruzitabwaho. Modulator yumva afite agace. Gutanga neza birashobora kunoza ibipimo bizengurutse hejuru ya 10db. Mu bushakashatsi bwakozwe na Lab, mubisanzwe umugenzuzi ukenewe.
3. Abagenzuzi babikwiye. Mu bipimo byacu bya DC biba igeragezwa, 50.4DB Kuzimira. Mugihe datasheet ya modulator ikora gusa urutonde rwa 40DB. Impamvu yo gutera imbere nuko modulatoriya bamwe bagenda vuba cyane. Rofea R-Bc-Umuntu wese ushinzwe kugenzura kubogama uboab voltage buri cya kabiri kugirango hakemure igisubizo cyihuse.

1. Mer bivuga modulator yagabanijwe. Ikigereranyo kizimangirwa cyagezweho ni igipimo kizima cya Modulator cyerekanwe muri Modulator datasheet.
2. CSO bivuga itegeko rya kabiri rya kabiri. Gupima CSO neza, imirongo yuburinganire bwikimenyetso cya RF, Modulator n'abakire bagomba kubyemeza. Byongeye kandi, sisitemu Cso Gusoma irashobora gutandukana mugihe biruka kuri frequents zitandukanye za RF.
3. Nyamuneka menye ko iyinjiza imbaraga za optique zidahuye nimbaraga za optique kuritoranijwe. Bivuga imbaraga ntarengwa za optique ko modulator ishobora kohereza hanze kubagenzuzi mugihe bias voltage kuva -Vπ kugeza kuri + v.

1. Igenamigambi rikwiye guhitamo hagati yo kugenzura ifoto cyangwa gukoresha modulatriode yimbere. Birasabwa gukoresha ifoto yumugenzuzi ku bushakashatsi bwa laboratoire kubwimpamvu ebyiri. Ubwa mbere, umugenzuzi Photodiode yemeje ubuziranenge. Icya kabiri, biroroshye guhindura imyumvire yinjiza. Icyitonderwa: Niba ukoresheje Phodulatriode yimbere, nyamuneka urebe neza ko ibisohoka byubu foto bingana cyane kugirango ubone imbaraga.

Amplitude ya sisitemu ya rf nayo izagira ingaruka kubisobanuro. Iyo nta shuri rya RF rihari cyangwa RF yerekana ibimenyetso bito, umugenzuzi ashoboye gufunga akazi kugirango akosorwe na ms na plr gusimbuka. Iyo Ikirango cya RF kirenze urwego runaka, bashoferi ba sisitemu izahindurwa, muriki gihe, umutwe wa PLR ugomba kuba muburyo bunyuranye, ni ukuvuga ko umusingi agomba kwinjizwamo niba yinjijwemo niba byinjijwe.
Porogaramu isanzwe
Umugenzuzi aroroshye gukoresha.
Intambwe1. Huza icyambu cya 1% ya coupler kuri Photodiode yumugenzuzi.
Intambwe2. Huza Bias Voltage Ibisohoka byumugenzuzi (binyuze muri SMA cyangwa 2.54mm 2-pin Umutwe) Kuri Bodulator.
