Ma waena o nā haneli he nui o nā pono hana i loaʻa i ka mākeke no ke ana ʻana i ka ʻike ma kekahi hōʻailona uila, ʻelua o nā mīkini maʻamau ka multimeter a me ka oscilloscope. Akā ua hele lākou i loko o nā loli weliweli i nā makahiki i ʻoi aku ka maikaʻi a me ka maikaʻi i kā lākou hana.
ʻOiai he ʻano like ka hana o kēia mau hāmeʻa ʻelua, ʻaʻole like ʻelua i ka ʻōlelo o ka hana a me nā hiʻohiʻona. Loaʻa iā lākou kekahi mau hiʻohiʻona kikoʻī e hoʻolilo iā lākou i nā kahua wale nō. E haʻi mākou iā ʻoe i nā ʻokoʻa āpau ma waena o kēia mau hāmeʻa ʻelua i ʻike ʻoe i kahi e ʻoi aku ka pono iā ʻoe ma lalo o nā ʻano ʻokoʻa.
Ke hoʻokaʻawale ʻana i ka Oscilloscope i kahi Multimeter Graphing
Ke makemake ʻoe e ʻike i nā ʻokoʻa ma waena o nā mea ʻelua, pono ʻoe e hoʻohālikelike i ko lākou hiʻohiʻona a ʻike i ka mea e hana i kahi ʻoi aku ka maikaʻi o ka hana no kekahi hana. A ʻo ia nō kā mākou hana ma aneʻi. Ua hana mākou i kahi noiʻi ākea a me ka noiʻi ʻana i nā kumumea i hoʻokaʻawale i kēia mau mīkini ʻelua, a helu ʻia nā mea ma lalo iā ʻoe.
Mōʻaukala o ka hana ʻana
ʻOiai ka mea hoʻoneʻe-pointer mea mua e hoʻokumu ʻia ʻo ka galvanometer i ka 1820, ua hoʻokumu ʻia ka multimeter mua i nā 1920 mua. Ua hoʻokumu ka ʻenekini Pelekane Pelekane ʻo Donald Macadie i ka mīkini e hoʻonāukiuki nei me ka pono e lawe i nā pono he nui e pono ai no ka mālama ʻana i nā kaʻa telecom.
Ua hoʻokumu ʻia ka oscilloscope mua ma 1897 e Karl Ferdinand Braun, nāna i hoʻohana i ka Cathode Ray Tube (CRT) e hōʻike i ka neʻe ʻana o kahi koho balota e neʻe mau nei e kū ana i ke ʻano o kahi hōʻailona uila. Ma hope o ke kaua honua ʻelua, ua loaʻa nā pahu oscilloscope ma ka makeke ma kahi o $ 50.
Bandwidth
Loaʻa nā oscilloscope haʻahaʻa haʻahaʻa i kahi bandwidth hoʻomaka o 1Mhz (MegaHertz) a piʻi i kahi mau MegaHertz. Ma ka lima ʻē aʻe, he bandwidth o 1Khz (KiloHertz) wale nō kahi graphing multimeter. ʻOi aku ka nui o ka bandwidth i nā scans hou aʻe i kēlā me kēia kekona e hopena ai i nā ʻano nalu pololei a kikoʻī.
Nā Manaʻo: Ka nui a me nā ʻāpana maʻamau
ʻO Oscilloscope nā māmā a me nā pono lawe lima e like me ka pahu liʻiliʻi. ʻOiai aia kekahi mau kumu hana kūikawā e kau ʻia i luna. ʻO ka multimeter grapaging, ma ka lima ʻē aʻe, liʻiliʻi e lawe i kāu ʻeke.
Aia nā kaohi a me ka pale ma ka ʻaoʻao hema a me ka ʻākau o ka oscilloscope. I ka oscilloscope, nui ka nui o ka pale ke hoʻohālikelike ʻia i ka paku liʻiliʻi o kahi multimeter graphing. Uhi ka pale ma kahi o 50% o ke kino o ka hāmeʻa ma ka oscilloscope. Akā ma ka multimeter graphing, ma kahi o 25%. ʻO ke koena no nā kaohi a me nā hoʻokomo.
Nā waiwai pale
ʻOi aku ka nui o nā pale Oscilloscope ma mua o ka multimeter graphing. Ma ka pakuhi o ka oscilloscope, aia kahi pūnaewele me nā pahu liʻiliʻi i ʻike ʻia nā mahele. Hāʻawi kēia i ka maʻalahi a me ka maʻalahi e like me ka pakuhi kiʻi maoli. Akā ʻaʻohe grids a mahele paha i ka pale o ka multimeter graphing.
Nā awa no nā Jack hoʻokomo
ʻO ka maʻamau, aia nā kahawai komo ʻelua ma ka oscilloscope. Loaʻa i kēlā me kēia kahawai hoʻokomo kahi hōʻailona kūʻokoʻa e hoʻohana ana i nā probes. I ka multimeter graphing, aia he 3 awa komo i kapa ʻia COM (maʻamau), A (no kēia manawa), a me V (no ka uila). Aia kekahi awa no kahi mea kūwaho kūwaho i ka oscilloscope kahi e noho ʻole ana ma ka multimeter graphing.
kumu hoʻohālikelike a
Hoʻokaʻawale ʻia nā kaohi i ka oscilloscope i ʻelua mau ʻāpana: ʻo ka pākū a me ka pae. Mālama ka ʻaoʻao papamoe i nā ʻano o ka axis X o ka pakuhi i hana ʻia ma ka pakuhi. Hoʻopili ka ʻaoʻao kū i ka axis Y. Eia nō naʻe, ʻaʻohe mana no ka kaohi ʻana i ka pakuhi i ka multimeter graphing.
Aia kahi pihi nui i kahi multimeter graphing e pono ai ʻoe e huli a kuhikuhi i ka mea āu e makemake ai e ana. ʻO kahi laʻana, inā makemake ʻoe e ana i ka ʻokoʻa voltage, a laila pono ʻoe e hoʻohuli i ka pihi i ka "V" i kaha ʻia a puni ka pihi. Aia kēia mau kaohi e pili ana i ka pale o ka oscilloscope, ma mua pono o ka ʻaoʻao kū.
I ka multimeter graphing, ʻo ka hopena paʻamau ka waiwai. No ka kiʻi ʻana i ka pakuhi, pono ʻoe e kaomi ma ke pihi "Auto" ma lalo pono o ka papakaumaka. E hāʻawi ʻo Oscilloscope iā ʻoe i kahi pakuhi ma ke ʻano paʻamau. Hiki iā ʻoe ke kiʻi i ka ʻike hou aʻe ma ka pakuhi e hoʻohana ana i nā knobs ma ka piko a me ka ʻaoʻao pae a me ka panela e pili ana i ka pakuhi.
ʻO nā pihi no ka hoʻopaʻa ʻana i kahi waiwai a me ka hoʻokuʻu ʻana i ka waiwai no nā hoʻokolohua hou aia ma hope pono o ke pihi "Auto". ʻO nā pihi no ka mālama ʻana i nā hopena ma ka oscilloscope e loaʻa maʻa mau ma luna o ka ʻaoʻao kū.
Nā ʻano o ka holoi
In he oscilloscope, hiki iā ʻoe ke hoʻopilikino i kāu sweep no ka loaʻa ʻana o kahi pakuhi ma lalo o nā koina kikoʻī hiki iā ʻoe ke hoʻonohonoho. Kapa ʻia kēia he triggering. ʻAʻole loaʻa kēia koho i nā multimeter kiʻi kiʻi a ʻo ka hopena, ʻaʻohe o lākou ʻano o ka sweeps e like me ka oscilloscopes. Kōkua nā Oscilloscopes i ka noiʻi ma muli o ka hiki ke hoʻoulu.
papakaumaka
Hiki i nā oscilloscopes hou ke kiʻi i nā kiʻi paʻi kiʻi o ka pakuhi e hōʻike ʻia ana ma ka pale, a mālama iā ia no kekahi manawa ʻē aʻe. ʻAʻole wale ia, hiki ke hoʻololi ʻia kēlā kiʻi i kahi polokalamu USB pū kekahi. ʻAʻohe o kēia mau hiʻohiʻona loaʻa i ka multimeter. ʻO ka mea maikaʻi loa e hiki iā ia ke mālama i ka nui o kekahi mea.
pūnaewele
Hiki i nā oscilloscope kiʻekiʻe ke mālama i nā kiʻi wale nō, akā hiki iā lākou ke mālama i nā kiʻi ola o kekahi palena manawa. ʻAʻole loaʻa kēia hiʻohiʻona i nā multimeter graphing ma ka mākeke. Ma muli o kēia hiʻohiʻona, e lilo ana nā oscilloscope i mea makemake nui ʻia no nā hana noiʻi, no ka mea hiki iā lākou ke mālama i nā ʻike maʻalahi no ke aʻo ʻana i ka wā e hiki mai ana.
Kahua Hana
Hoʻohana ʻia ka multimeter Graphing a hiki ke hoʻohana wale ʻia i ke kahua o ka ʻenehana uila. Akā ke hoʻohana ʻia nei nā oscilloscope i ke kahua o ka ʻepekema ʻepekema ma kahi o ka ʻenekini uila. ʻO kahi laʻana, an Hiki ke hoʻohana i ka oscilloscope e ʻike i nā puʻuwai o ka mea hoʻomanawanui a loaʻa i ka ʻike koʻikoʻi e pili ana i ka puʻuwai.
kāki
ʻOi aku ka maikaʻi o nā oscilloscope ma mua o ka grapher multimeter. Hoʻomaka maʻamau ʻo Oscilloscope mai $ 200 a ʻoi aku. Ma ka ʻaoʻao ʻē aʻe, hiki ke ʻike ʻia nā graphes graphing ma kahi o $ 30 a $ 50 paha.
No ka hōʻiliʻili iā ia
ʻOi aku ka nui o nā hiʻohiʻona o Oscilloscope ma mua o ka multimeter graphing. Eia kekahi, ʻaʻole kokoke kahi multimeter graphing i kahi oscilloscope ke pili i nā mea hiki iā ia ke hana. Me ia e ʻōlelo ʻia, ʻaʻole hiki iā mākou ke ʻōlelo i ka oscilloscope e kuʻi i ka multimeter i kēlā me kēia mahele a pono ʻoe e kūʻai i kahi oscilloscope wale nō.
No nā hana noiʻi ʻo Oscilloscope. E kōkua ia e ʻike i nā hewa i ke kaapuni e koi ai i nā nalu kikoʻī a maʻalahi hoʻi. Akā, inā ʻo kāu pahuhopu ke loaʻa wale i kekahi mau nui a nānā i ke ʻano o ka nalu, a laila hiki iā ʻoe ke hoʻohana maʻalahi i ka multimeter graphing. ʻAʻole ia e pau iā ʻoe i kēlā ʻano.
E heluhelu paha ʻoe: Pehea e hoʻohana ai i kahi Oscilloscope
ʻO wau ʻo Joost Nusselder, ka mea nāna i hoʻokumu i ke Kauka Mea Hana, mea kūʻai maʻiʻo, a me ka makuakāne. Makemake au i ka hoʻāʻo ʻana i nā mea hana hou, a me kaʻu hui ua hana au i nā ʻatikala blog hohonu mai ka makahiki 2016 e kōkua i ka poʻe heluhelu kūpaʻa me nā mea hana a me nā ʻōlelo aʻoaʻo.
