  • Kuchuluka kwa zitsanzo kapena mafupipafupi (Sa/so Zitsanzo pa Sekondi iliyonse): iwonetsa kuti tsatanetsatane kapena mafunde omwe amayezedwa amatengedwa kangati pa nthawi. Kukwera kuli, kuwongolera bwino komanso mwachangu kudzagwiritsa ntchito kukumbukira. Muyenera kusankha oscilloscope yomwe ili ndi nthawi zosachepera 5x kuchulukitsa kwafupipafupi komwe mukupita kusanthula.
  • Kuyambitsa kapena kuyambitsa: Zabwino kwambiri ngati zimapereka zoyambitsa zotsogola zamawonekedwe ovuta. Zikakhala bwino, mudzatha kuzindikira zolakwika zomwe zingakhale zovuta kuzipeza.
  • Kuzama kwa kukumbukira kapena kutalika kwa mbiri (pts): Kuchuluka, kusinthika kwabwinoko kwamasigino ovuta. Imawonetsa kuchuluka kwa mfundo zomwe zitha kusungidwa pamtima, ndiko kuti, kuthekera kosunga zotsatira zam'mbuyomu poyesa. Kuchuluka kwa zowerengedwa kumatha kujambulidwa ndipo zikhalidwe zonse zitha kuwoneka kuti zitha kutsimikizika bwino kapena kutsata.
  • Chiwerengero cha njira: Sankhani oscilloscope ndi nambala yoyenera ya mayendedwe, njira zambiri, zambiri zitha kupezeka. Ma analogi anali kukhala ma tchanelo a 2 okha, pomwe a digito amatha kuchoka pa 2 kupita mmwamba.
  • Chiyankhulo: Ziyenera kukhala zachidziwitso komanso zosavuta momwe zingathere, makamaka ngati ndinu woyamba. Ma oscilloscope ena apamwamba ndi oyenera akatswiri okha, popeza wogwiritsa ntchito wosadziwa amafunikira kuwerenga bukuli mosalekeza.
  • Analogi ndi digito: ma digito pakali pano ali otchuka pamsika chifukwa cha ubwino wawo, monga kulola kumasuka kwambiri, komanso popanda malire pa kutalika kwa zolembazo. Chifukwa chake, njira yomwe mumakonda iyenera kukhala digito oscilloscope pafupifupi pafupifupi milandu yonse.
  • Malonda: Mitundu yabwino kwambiri ya oscilloscope ndi Siglent, Hantek, Rigol, Owon, Yeapook, ndi zina. Choncho, kugula imodzi mwa zitsanzo zawo kudzakhala chitsimikizo cha ntchito yabwino ndi khalidwe.

Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
