Kodi kupanga oscilloscope ku khadi phokoso

Lililonse wailesi ankachita masewera ali kukhala chipangizo, monga oscilloscope zasayansi kwawo. Iye chofunika kuti akakonze ndi kusintha madera amagetsi. Ndiponso, popanda anati chipangizo Kodi sakwanitsa kuphunzira madera atsopano ndi katundu wawo. Komabe, mtengo wa digito ndi analogi oscilloscope si mkulu. Mukhozanso kuyesa kupeza chipangizo ntchito, koma zipangizozi palibe aliyense pa m'thumba. Nkhaniyi ikusonyeza momwe kuti oscilloscope ku khadi phokoso. Mtengo wa zosinthidwa amenewa ndi negligible, chifukwa maziko chipangizo anati akutenga PC gawo. Kusonyeza waveform ntchito pulogalamu yapadera.

Oscilloscope phokoso khadi: ubwino ndi kuipa

Ubwino chipangizo pansi kulingalira monga mtengo wotsika, ndithudi, kupatulapo kompyuta payokha. Tsopano zovuta. Paja: kudzakhala kuposa phindu. The sangathe waukulu, umene amakhala ndi oscilloscope ku khadi phokoso - ichi ndi mkulu kwambiri tilinazo. Amachitira ngakhale wailesi kuwasokoneza, chifukwa mu waveform akhoza kukhala zolakwika. The sangathe chachiwiri ndi chakuti kugwiritsa athandizira ndi phokoso khadi pakhale chizindikiro matalikidwe si upambana 2 V. Izi zikutanthauza kuti khadi mosavuta kuonongeka. vuto limeneli tiyenela kuiganizila kupanga adaputala lapansi. The oscilloscope wa khadi phokoso sangathe kuyeza DC voteji.

Kodi kupanga adaputala

Choyamba m'pofunika kuganizira msinkhu Muzifunsa khadi phokoso, nthawi zambiri si volts oposa awiri, ndipo ena matabwa - zosakwana Volt wina. Mwachibadwa, zingakhale osakwanira kwa muyeso wa matalikidwe izi. Izi zimafuna adaputala kuti adzalola kuonjezera malire a matalikidwe chizindikiro. Mapulogalamu - oscilloscope - ali awiri mlingo miyezo chovomerezeka: 12,5 V ndi 250 V. chojambula chithunzi cha chipangizo chotero limapangidwa zinthu zisanu ndi chimodzi chokha - resistors. R1 ndi R2 ali mwadzina kukana 1.5 Mohm, R3 ndi R4 - 75 ohms, R5 ndi R6 - 1,5 kohm. Mphamvu madyaidya ndikuledzera resistors ayenera kukhala osachepera 0.5 Watts. dera ali ndi polowera 5 ojambula (awiri - kuchokera ku gwero chizindikiro 250, awiri - 12,5 The chachisanu ndi - chonse - kutsogolera) ndi atatu linanena bungwe pa linanena bungwe olumikizidwa kwa mzere Muzifunsa khadi phokoso (kumanzere ndipo m'njira yoyenera ndi adagawa).

Ife chitani za mfundo adaputala. Anthu awiri oyambirira a zolowetsa - "gwero 250" - chikugwirizana ndi resistors R1 ndi R2, zina - ndi R3 ndi R4; pa osachiritsika linanena bungwe, motero, anachoka ndi njira zolunjika za mzere athandizira. A awiri yachiwiri "gwero la 12,5 V" "kusiyana" chikugwirizana pakati resistors ndi, i.e. wina osachiritsika - pakati R1 ndi R3, ndipo chachiwiri - pakati R2 ndi R4. Ndipo potsiriza, wotsiriza, linanena bungwe okwana zimapita kwa cholumikizira mzere mu phokoso khadi. Kumakhudzana ndi mitsinje lamanzere ndi lamanja kudzera resistors R5 ndi R6, chikugwirizana pambuyo awiri resistors R3 ndi R4. Pofuna kuchepetsa zotsatira za phokoso pa chipangizo, uchiike adaputala bolodi kwa nyumba zitsulo. Apa, mu Ndipotu oscilloscope lonse. Khadi phokoso alandira chizindikiro ukubwera, ndi mapulogalamu amasonyeza waveform pa polojekiti kompyuta.

Kukhazikitsa pulogalamu

Kusintha oscilloscope ku khadi phokoso, muyenera kupita akakhale opanga PC ndi zimitsani phindu pa maikolofoni, anapereka mlingo buku ndi Aperewera. Chifukwa kuyeza chipangizo amatha kutolapo bwino waveform m'malo otsika pafupipafupi, ndi kudziwa pafupipafupi cha chizindikiro.
