Kei konei katoa ngā mōhiotanga e hiahiatia ana e koe mō te whakamātautau ara iahiko whakauru mō te mīhini tākai.

Ko te whakamātautau ara iahiko whakauru mīhini tākai matua ko te ine i ngā pūwāhi whakamātautau matua. Ko te tikanga whānui ko te whakamahi i te taputapu hei whakamātautau i ia waewae o te hiko me te ātete pine ki te whenua, kia rerekē ai te hiko whakauru me te hiko putanga, te kai hiko me te ngaru whakauru/putanga, ā, kia rerekē ai ngā hua whakamātautau ki ngā tawhā ara iahiko whakauru noa, kia taea ai te whakatau he noa te ara iahiko whakauru hei whakamātautau.

i roto i te mīhini tākai , ngā tukatuka hiko whakauru e whakamahia whānuitia ana, te hiko whakauru kiriata matotoru me te IC whakakaha whakahaere pūngao pana. Me tātari taipitopito tātou mō ēnei.

mīhini tākai whakamātautau ara iahiko whakauru i roto i te kī o ngā pūwāhi whakamātautau ara iahiko whakauru.

1. Te kī ki te pūwāhi whakamātautau ara iahiko whakauru moroiti

Ko te kī ki te pūwāhi whakamātautau hiko whakauru moroiti ko te taha tuku hiko VDD, te TAUTAHI, te TAUTAHI, te whakauru tohu wiri karaihe IN, te mutunga putanga tohu wiri karaihe Xor o te whakauru, te putanga, me ētahi atu ara iahiko.

Mā te whakamātautau ipurangi ka ine i te pūwāhi matua o te ātete me te uara ngaohiko, ā, ka taea te whakatau he noa te ara iahiko whakauru;

2. Te kī o te pūwāhi whakamātautau IC pūhiko whakawhiti

Ko te mea nui ki te pūwāhi whakamātautau IC whakawhiti hiko ko te pito whakauru kitenga Vc, te ngaohiko, te whakaurunga kitenga o ia au, te putanga pulse, me ētahi atu.

I whakamahia te whakamātautau ipurangi hei ine i te ngaohiko o te ara iahiko whakauru me te ātete o ia pine, kātahi ka whakatauritea ki ngā raraunga noa, pērā i te rerekētanga nui, me whakamātautau anō hoki i ngā wāhanga e pā ana, ka whakatauhia te wāhanga i raro i te āhua noa, ka taea te whakatau kua pakaru te ara iahiko whakauru. I roto i te pana ara iahiko whakauru, ko te ngongo pana te wāhanga matua, ko te kiriata matotoru o te ara iahiko whakauru o te ngongo pana mana nui, ina kore e pai te ruarua, ka taea te ine i te ngongo pana mā te ngongo pana c, b, e i waenganui i te ātete whakamua me te whakamuri ki te whakatau.

3. Pūwāhi whakamātautau matua o te whakakaha whakahaere IC

Ko te wāhi matua o te whakamātautau IC whakakaha whakahaere ko te wāhi whakauru me te wāhi whakaputa. He teitei ake te uara ngaohiko pūmau o tēnei wāhi.

Hei whakamātautau, mā te mita maha ki te hiko hiko DC, me ine i te uara hiko putanga i waenga i te pito me te pito hiko kino. Mā te whakamahi i ngā tweezers whakarewa ā-ringa, ka patohia ngā pito whakauru e rua o te whakakaha whakahaere (honoa te tohu aukati), ka mātakitaki i te āhua o te wiri o te karaka. He mea noa, ka nui ake te wiri o te tohu mita maha, ki te kore te tohu e neke, kua pakaru te whakakaha whakahaere. 4. Whakamātautau tohu ara iahiko whakauru motuhake mō te pahikara hiko.

I roto i te mīhini tākai, ko te ara iahiko whakauru TL494 e whakamahia whānuitia ana, ko te ara iahiko me te ara iahiko. Me titiro motuhake tātou ki ngā āhuatanga matua o ngā tikanga whakamātautau motuhake (1) Te whakatau i te ara iahiko whakauru T494

Te whakamātautau i te ara iahiko whakauru mīhini tākai hei whakatau i te ara iahiko whakauru T494 i roto i ngā taahiraa e whai ake nei.

1) Whakaritea te taputapu. Whakamātautauhia ngā ara iahiko whakauru hei whiriwhiri i ētahi atu mahi, pērā i te mita maha mamati, ngā tauira me te momo mahi MY68 me te mita maha mamati momo MS820.

Ka taea e rātou te kite i te auau o te 150 KHZ me te 200 KHZ. Me whai hoki i tētahi oscilloscope, he takai waea ātete ka taea te whakarite, me ētahi atu.

2) Ine i te auau o te wiri. Tuatahi, tirohia te mita maha-whakawhiti ki te 200 KHZ, tirohia te tere o te wiri T494 (mō ētahi atu ara iahiko whakauru pēnei i raro i te 200 hz, ka taea te whakarite i te taputapu), kia tika ai. Ko te wiri T494 he 5, he 6 putu te tawhiti, nō reira ka taea e ngā pene mita maha te whakatau i te ngaru niho kani i roto i ēnei waewae e rua. Ko te auau wiri o te ara iahiko utu me te whakahaere he 20 ~ 80 kh, ko ngā hua whakatau he uara motuhake, he noa te wiri o te ara iahiko whakauru, he tika te uara kaha ātete.

Ki te kore he tohu o te wiri, me tirotiro te pūwāhi whakapā me ngā pene me ngā waea, me ētahi atu. Ki te iti tonu te whakamātautau anō i te inenga tau o te ara iahiko whakauru, he raruraru tērā.

Ki te kore e whakaaetia te auau tirohanga, me kī atu ki te Rr, ki te Cr rānei, me whakarerekē, me whakakapi rānei te āhua tirohanga e tika ana.

3) Te ine i te ōwehenga mahi. Kia rite ki te oscilloscope, ka puta te pine putanga T494 9, 10, ka honoa te atanga whakauru o te oscillograph, ka neke whakamua ki te 9, 10 putu me te kawenga kua whakatauria. He mea nui kia mōhio kei konei kāore he kawenga kua whakatauria, kāore te ōwehenga mahi e ine tika, ka rerekē mai i te uara o te hoahoa taketake. Tirohia te oscilloscope 9, 10 putu o te ngaru putanga, i te wa ano ka whakatikatika i te ōwehenga mahi: hei whakahaere i te huānga, whakatikatikahia te kakau whakahaere tere, mā te 0 hurihuri; Ki te rihi, whakatikatikahia te uara ātete mai i te 0 ki te 6 putu (Ko te kaha C, i te wa ano ka whakatikatikahia). I tēnei wā, me kite te oscilloscope i ngā huringa ōwehenga mahi mai i te kore ki te 100 ōrau.

He mea nui te whakamātautau i te ara iahiko whakauru o te mīhini tākai, ā, e tika ana kia mahi noa te mīhini. Ko te tumanako ka whai hua tēnei tuhinga ki a koe mō te whakamātautau i te ara iahiko whakauru o te mīhini tākai.
