FAQ
Q1: Sidee si dhakhso ah loo go'aamiyaa in la isticmaalo heerkul cidhiidhi ah ama ballaaran marka la dooranayo qiyaasta heerkulka hawlgalka?
J: Tixgeli goobta uu ku shaqaynayo aaladda. Alaabta elegtarooniga ah ee caadiga ah ee gudaha ah (tusaale, kuwa ku hadla Bluetooth), dooro nooca heerkulka cidhiidhiga ah (-20 ~ +70 degree). Gawaarida, qalabka bannaanka, ama xaaladaha kale ee leh kala duwanaanshiyaha heerkulku, mudnaan sii nooca cabbirka heerkulka ballaaran (-40 ~ +85 digrii).
Q2: Waa maxay macnaha heerka gabowga ee oscillator-ka crystal, oo miyaynu ka walaacsanahay?
J: Waxa ay tilmaamaysaa kala duwanaanshaha soo noqnoqda sannadlaha ah. Heerka da'da ee 3ppm/sanad waa dayacan-aladaha caadiga ah waxay shaqayn karaan sanado iyada oo aan la arki karin khaladaad. Qalab sax ah -sare-, qalabaynta caadiga ah ayaa ku filan.
Q3: Sida loo doorto awoodda culeyska ee fursadaha jira ee 7pF/9pF/12.5pF?
A: Dooro ku salaysan shuruudaha naqshadaynta wareegga. Tixraac buug-gacmeedka qalabka ama nala tasho ka hor si aad u hubiso in xajmigu iswaafajiyo, dammaanad qaadka soo-saarka joogtada ah ee oscillator-ka crystal.
