Maxaa la qiyaasi karin, by analyzer spectrum a

Waa maxay analyzer spectrum ah? Iyada oo alaabta this aad marna la kulmi doonaan nolol maalmeedka, waa arrin qalab gaar ah, oo waa qaali. In this article, waxaan ka fiirsan doonaan utility iyo isticmaalka qalabka sida. In si kooban u dhigo, analyzer spectrum waa qalab in lagu tilmaami karaa voltmeter ah inta jeer ee doorashada, taas oo oogaatid Ilodanimada, waxaa loo qaybiyay si ay u muujiyaan qiimaha RMS ee la ruxruxo Culumida Soomaaliyeed. Iyo in kaliya ee kooban, waxa run ahaantii waa wax intaas ka sii adag oo xiiso leh.

Waxaa muhiim ah in la fahmo in qalab this ma aha meter xoogga, inkastoo xaqiiqda ah in analyzer spectrum si toos ah usoo saari karnaa qiimaha dhimaya this. Haddii aan ogaado qiimaha celcelis ahaan ama ugu sarreysa ee la ruxruxo Culumida Soomaaliyeed iyo qiimaha iska caabin ah, waxaa suurtagal ah in reserved qalab ay muujiyaan qiimaha wax soo saarka. Thanks to horumarinta technology digital, analyzers spectrum casriga leeyihiin fursadaha si dhab ah u ballaaran.

Si loo fahmo ujeedada qalab this, waxaa lagama maarmaan ah in la tixgeliyo waxa qiyaastay analyzer spectrum ah. kuu sheegi karaa magaca qalab ah in loo isticmaalo in lagu cabbiro spectrum ah. Iyo nooca sifooyinka? spectrum waa set oo ah hirarka sinusoidal, taas oo at-gaynta qaarkood ay awoodi karaan inay ku siiyaan signal a warbixinta domain waqti qeybaha. Sida habboon, signal uu leeyahay qaab sinewave hal classical. In dhaqanka, in domain inta jeer ee la analyzer spectrum ah ayaa loo arki karaa in spectrum of signal ka kooban yahay laba hirarka ama in ka badan, waxaa ku jiri kara labaad harmonic iyo kuwa kale. In domain markii si fudud loo qiyaasi karin, ku laayeen garaaca wadnaha duration iyo qarkiisa ka dhicin, iyo sidoo kale qiiqa iyo runout signal . signal cabbirka analyzer spectrum in domain inta jeer ee loo baahan yahay marka la dhigaayo a nidaamyada isgaarsiinta wireless. iyadoo la kaashanayo of qalab this Keliya waxaa suurtagal ah in la ogaado oo markii danbe la baabi'iyo-band iyo qiiqa abuur ah. Sida kor ku xusan, qalab ogol yahay in la ogaado signal harmonic dheeraad ah, iyo dhimaya ee hay'adaha gudbinta radio waa muhiimad weyn, maxaa yeelay, harmonics dheeraad ah ku dhici karaa inta jeer ee u shaqeeya, Kuna keeni faragelin.

Sidoo kale, qalab this u dhaqmo sida analyzer ku spectrum audio. Maxay ka dhigan tahay? Mararka qaarkood waxaa lagama maarmaan ah si ay u fuliyaan cabbirka sanqadh sida signal caadi ah. qalab kasta ama circuit firfircoon ahbaa buuq. cabirka ratio qaylada noocan oo kale ah iyo ratio signal / buuqa jira sifooyin muhiim ah qalabka iyo nidaamka tilmaame caadi ah.

Gebogebadii, waxaannu nidhaahnaa kit elektaroonik ah si ay u tijaabiso iyo Debug qalabka loogu talagalay oo kaliya u baahan tahay analyzer spectrum ah. Qiimaha qalab this waa arrin muhiim ah oo kala duwan in ka badan ballaaran oo kala duwan. Tusaale ahaan, mid ka mid ah qalabka fudud (Rigol DSA815) kici doonaa oo ku saabsan 50-60 kun oo rubles, wuxuuse lahaan doonaa inaad bixiso 750-800 kun rubles for analyzer xirfadda spectrum (Agilent Technologies). hiwaayadda Radio siminaarka guriga uu yahay lagama yaabo in la iibsan qalab noocan oo kale ah, laakiin shirkadaha ama laboratories ah shirkadaha ku hawlan horumarinta technology elektaroonik ah, waa waajib.
