Yini engase alinganiswe ngumuntu analyzer bohlu

Uyini analyzer spectrum? Nge lo mkhiqizo awusoze sibhekane nabo ekuphileni kwansuku zonke, sekuyinto namadivayisi athile, futhi ngempela eqolo. Kulesi sihloko, sizoxoxa Umbuso indawo ukusetshenziswa kwamadivaysi anjalo. Ngamafuphi, le analyzer spectrum umshini lingachazwa ngokuthi imvamisa voltmeter abakhethayo, okuyinto iphendula amplitude, ilungiswe ukuze sibonise RMS ukubaluleka wave sine. Futhi yilokho nje in a Ngamafuphi, empeleni ukuba yinkimbinkimbi kakhudlwana futhi ezithakazelisayo.

Kubalulekile ukuqonda ukuthi leli thuluzi akulona imitha amandla, naphezu kweqiniso lokuthi analyzer spectrum kungaba ngokuqondile ukubonisa ukubaluleka kwalesi ipharamitha. Uma sazi ukubaluleka isilinganiso noma isiqongo we wave sine futhi ukubaluleka ukumelana, kungenzeka ukuthi lilungiselele idivayisi ukubonisa amagugu okukhiphayo. Siyabonga ekuthuthukiseni ezobuchwepheshe, yesimanje spectrum analyzers abe amathuba ebanzi ngempela.

Ukuze siqonde injongo yalesi insimbi, kubalulekile ukucabangela lokho kukalwa nge analyzer bohlu. ungakwazi ukutshela kusuka egameni idivayisi ukuthi isetshenziselwa ukukala bohlu. Futhi hlobo luni izici? Nomkhakha iqoqo amagagasi sinusoidal, ngaleso inhlanganisela ethile bayakwazi ukunikeza isignali sokubika Sectional isikhathi kwesizinda. Kahle kahle, isignali has ngesimo sinewave olulodwa classical. Ekusebenteni, esizindeni imvamisa nge analyzer spectrum kuyabonakala ukuthi nomkhakha we isignali siqukethe amagagasi ezimbili noma ngaphezulu, kungase aqukethe harmonic yesibili nabanye. Esikhathini lesizinda isikhathi kalula lingalinganiswa isikhathi ishayela onqenqemeni futhi usiko falling, kanye emkhathini kanye isignali runout . isignali spectrum analyzer izilinganiso kusizinda imvamisa kuyadingeka uma ukuklama zokuxhumana izikimu engenantambo. Kuphela ngosizo kule divayisi kungenzeka ukuthola kamuva ukuqeda-band nentuthu oyikhiphayo ezikhohlisayo. Njengoba kushiwo ngenhla, idivayisi evumela ukuhlonza isignali harmonic ezengeziwe, futhi ipharamitha e apharathasi omsakazo kubaluleke kakhulu, ngoba Harmonics ezengeziwe angawa nobuningi baqashwe futhi ngaleyo ndlela kudale isiphazamiso.

Futhi, le divayisi uba umsindo spectrum analyzer. Kusho ukuthini? Ngesinye isikhathi kuyadingeka ukuba afeze umsindo izilinganiso njengesignali ye abavamile. Noma iyiphi idivayisi noma wesifunda asebenzayo elakhiwe umsindo. Okunjalo umsindo isilinganiso ukulinganiselwa isignali / umsindo isilinganiso kuyizici ezibalulekile zedivayisi ejwayelekile inkomba kanye uhlelo.

Efingqa, sithi ikhithi electronic ukuhlola Debug imishini yakhelwe nje badinga analyzer bohlu. Intengo yale divayisi kuyaphawuleka ngempela futhi luyehluka ezahlukahlukene. Ngokwesibonelo, omunye amadivayisi elula (Rigol DSA815) izobiza ruble ecishe ibe yizinkulungwane 50-60, kodwa kuyodingeka ukuthi bakhokhe ama-ruble ayizigidi 750-800 for the professional spectrum analyzer (Agilent Technologies). Radio amateur ekhaya lakhe workshop akunakwenzeka ukuba ukuthenga leli thuluzi, kodwa izinkampani noma laboratories izinkampani wahlanganyela ukuthuthukiswa yobuchwepheshe bama-electronic, kuba kumelwe.
