Pehea e hana i oscilloscope mai kou kamepiula?

Oscilloscope o kekahi o ka ua ki nei mea kani, e like kekahi lolouila hanalima noi keʻena hoʻokolohua a me kaʻike mau Radio Workshop. Ia ia pela, he mea ia mea hiki e hooholo i ka holo pono o ka lolouila i puhi ai, a no hoi e debug kā lākou hana ma ka manao o ka hou manaʻo. Naʻe, i ke kumukuai o ia mau mea i ka loa kiʻekiʻe, aʻaʻole na Radio loira hiki ke hoolawaia ma ke kuai ia heʻuʻuku lā. He 'atikala epa me ka ninau ana pehea e e ka oscilloscope mai kāu kamepiula. Ua nui ano o manufacturing ia i kekahi mea, akā, i ka hookumu ana o na wahi a: like me ka papa i eʻae impulses mea he PC kani kāleka, a me ka hana mea hoʻopili pili ia ia. Ua lawelawe 'ana i ka harmonize i ka pae o ka ana neaiaea a me ka hoʻokomo o nā leo kāleka o ke kamepiula.

Oscilloscope ma kekahi kamepiula: lako polokalamu

Kekahi o na kumu nui hehee wale o ka mea o ka lako polokalamu i e uku i ke kanaka hoʻoponopono lāʻau ikiʻai wale ana. Aia mea he nuiʻano o ka lako polokalamu, akā, i nāʻaha hui uila i hale lio. No mahalo i waena o aeoaeuneiai Radio hoʻohana lako polokalamu oscilloscope Osci, mai ke kini puʻe wale AudioTester. Ua loaʻa he mau 'mea ku pono e like me ka maʻamau Analog mea, i ka pale o ka maka aha e leie aku, e ana i ka lōʻihi like' ole a me ka ikaika hawewe o ke neaiaea. He kupono e hana, a i ka helu o nā hiʻona i loaʻa i loko o nā papahana o kēiaʻano. Akā,ʻo nā Radio loira e e hiki ke koho, e holo i ka lako polokalamu, i ka mea like.

oaoieei-ʻikepili

No laila, i mea e hana i ka oscilloscope mai kou kamepiula, e pono e ohi i ka kūikawā attenuator (anakahi uila mahele waiwai), a e e hiki ke uhi i laulā he laulā o ka hikiʻole ke ana anakahi uila. I ka lua o ka hana o ka mea hoʻopili - mea e hoʻopale ai i ka hoʻokomo o ke awa kani kāleka mai ka poho i hiki i kiʻekiʻe anakahi uila kaʻilikai. Hapanui kani pepa hoʻokomo o anakahi uila ua kaupalena 'ia 1-2 volts. Oscilloscope mai kāu kamepiula i ke alapine (frequency) huahelu o nā kino kīnā kani kāleka. No ka kāki pepa ia mea, mai 0.1Hz ia 20kHz (sinusoidal neaiae). I ka lalo anakahi uila kali, i hiki ke anaia ua kaupalena ma ke kāʻei kua 'ilikai a me ka leo a me ka mea 1 MV, a me ka luna - pūʻulu mea hoʻopili mea kiko'î, a hiki e mau haneri volts.

I hoʻomākaukauʻia anakahi uila mahele waiwai

Oscilloscope mai ke kamepiula i ka loa mea circuitry. Ua be elua wale zener diode a me ekolu resistors. Denomination resistors hilinaʻi nui ma luna o kaʻike kamepiula oscilloscope me ka unahiʻole. Kēia mahele waiwai no ka ekolu okoa unahi, a me ka lākiō. O 1: 1, 1:20 a me 1: 100. Alaila, o ka mea e i ekolu nā manaʻo, kela mea keia mea o ka i pili i ka mea pale mū holapū. Loipālākiō impedance kauoha hoʻokomo o mea pale mū holapū o 1 Mohm. Common alakaʻi mele ua pili ma nā aʻe pilina o nā Zener diodes. Ka mea, i ke hoʻololi e hoʻopale ai i ka laina-ma ke kani kāleka overvoltage, i ka wa a ke kuapo mea i loko o ka "pololei hoʻokomo o" kūlana. Nā resistors hiki ke pili ia laua i na capacitors, ka mea e flatten i ka ikaika hawewe-alapine (frequency) ke keʻena o ka mea.

ka hopena

Kēia oscilloscope kamepiula mea,ʻaʻole he maikaʻi ke nānā aku, i na mea kaapuni mea i manao ai, e ae i ka laulā huahelu o ana anakahi uila. I mai la na mea maalea, e kōkua ma ka hoʻoponopono 'ana i nā leo, a me ka hiki ke hoʻohana i ke ao ana noonoo.
