Momwe mungayendetsere oscilloscope: kalozera wa sitepe ndi sitepe

Oscilloscope ndi chida chofunikira chamagetsi chomwe chimagwiritsidwa ntchito m'magawo osiyanasiyana pazinthu zosiyanasiyana.

Ngakhale cholinga cha oscilloscope ndikungoyezera ma siginecha amagetsi komanso kuphunzira momwe ma siginecha amasinthira pakapita nthawi, chidacho chimakhalanso chothandiza pothetsa mabwalo amagetsi. 

Komabe, zotsatira zomwe mumapeza ndi oscilloscope zimatengera momwe zimawerengedwera bwino. Oscilloscope yolinganizidwa bwino imapereka zotsatira zolondola zomwe mungadalire, pomwe chida chosawerengeka bwino chidzasokoneza zotsatira zanu.

Chifukwa chake, mukufuna kuwongolera oscilloscope. Komabe, vuto lalikulu ndi momwe mungawerengere oscilloscope. 

Nkhaniyi ikupereka kalozera wagawo ndi sitepe pakuwongolera oscilloscope.

Kodi calibration ndi chiyani?

Calibration nthawi zambiri amafanizira zida ziwiri zoyezera. Posanja, chipangizo chimodzi chimapereka muyezo woyezera, ndipo chipangizo china chiyenera kugwirizana ndi muyezo womwe waperekedwa. 

Calibration imayang'ana kusiyana kwa zotsatira za kuyeza kwa zida ziwiri zoyezera ndikuwonetsetsa kuti zolondola pang'ono pazida ziwirizi zikukwaniritsa mulingo womwe umaperekedwa ndi cholondola. Njirayi ikufuna kuwongolera kulondola kwa zida, zomwe zimapereka zotsatira zolondola panthawi ya mayeso.

Kulinganiza kofananira kwamalonda kumachitika pogwiritsa ntchito njira zolozera komanso njira za wopanga. Muyezo nthawi zambiri umakhala wolondola kuwirikiza kanayi kuposa chida choyezera.

Choncho, kugwiritsa ntchito chida chatsopano kumapereka zotsatira zofanana ndi zida zina zolondola, pokhapokha ngati zikugwiritsidwa ntchito mofanana.

Kwa oscilloscopes, oscilloscope calibration ndi njira yosinthira oscilloscope kuti mupeze zotsatira mkati mwazovomerezeka. 

Momwe mungawerengere oscilloscope

Ngakhale ma oscilloscope amabwera m'mitundu ndi mitundu yosiyanasiyana, komanso njira yabwino yosinthira ma oscilloscopes osiyanasiyana imasiyanasiyana, bukhuli likuuzani momwe mungamalizire ntchitoyi.

Powerenga buku la malangizo a oscilloscope, muphunziranso zambiri zakuwongolera chida chanu.

Nawa masitepe ambiri kuti muwerenge oscilloscope:

1. Khazikitsani zowongolera zonse kukhala zabwinobwino

Onani zowongolera zonse ndikuziyika pamalo abwino. Ngakhale zosinthazi zimasiyanasiyana malinga ndi mtundu wa oscilloscope, ma oscilloscope ambiri amafuna kuti muyike pakati pama dials onse ndikuwonjezera mabatani onse. 

2. Yatsani oscilloscope

Ngati muli ndi CRT yachikale, ipatseni mphindi zochepa kuti mutenthe.

3. Khazikitsani kuwongolera kwa VOLTS/DIV kuzikhazikiko zomwe mukufuna.

Ngakhale mutha kusankha mtengo womwe mukufuna pagawo la VOLTS/DIV, ndikwabwino kuyiyika ku 1 kuti muyike. Kuyiyika ku 1 imalola oscilloscope kuwonetsa volt imodzi pamagawo molunjika. 

4. Ikani TIME/DIV pamtengo wotsika kwambiri

Izi, makamaka 1 ms, zimapatsa oscilloscope gawo lopingasa kuti liyimire nthawi. Tsatirani izi potembenuza kuyimba kamodzi kamodzi, pang'onopang'ono kusintha kadontho kukhala mzere wolimba.

5. Sinthani chosinthira choyambitsa kukhala "Auto".

Izi zimapangitsa kukhala kosavuta kuyang'ana mawonekedwe a mawonekedwe pazenera. Auto Trigger imathandizira kukhazikitsa malo oyambitsa wamba pa mawonekedwe a waveform kuti akhazikike. Popanda izi, chizindikirocho chimasuntha ndipo kumakhala kovuta kuchiwona. 

6. Lumikizani oscilloscope ku chizindikiro cholowetsa

Mukamayesa oscilloscope, ndikofunikira kuti mulumikizane ndi chizindikiro cholowera. Yambani ndi kulumikiza kafukufuku ku chida. Ngati muli ndi ma jaki angapo olowetsa, lumikizani sensa ku jack yolembedwa A. 

Oscilloscopes nthawi zambiri amakhala ndi kafukufuku wolowera ndi waya pansi / chingwe. Kufufuza kolowera nthawi zambiri kumalumikizidwa ndi chizindikiro cholowera, ndipo waya wapansi umalumikizidwa ndi malo aliwonse ozungulira. 

7. Lumikizani probe ku cholumikizira cholumikizira cha oscilloscope.

Izi zipereka ma square wave sampling omwe amafunikira kuti muwongolere chida chanu. Ma oscilloscopes ena amakhala ndi ma terminals awiri, nthawi zambiri 0.2V ndi 2V. Ngati chida chanu chili ndi ma terminals awiri, gwiritsani ntchito 2V pachifukwa ichi. 

Kuyika kafukufuku pa calibration terminal kungakhale kovuta, makamaka ngati ili ndi mapeto olunjika. Ngakhale kafukufuku woyeserera wa alligator ndi wosavuta kuyiyika pa calibration terminal, mwina simungamvetse momwe mungagwiritsire ntchito kafukufuku wolozera.

Ikani cholozera cholozera pa terminal pokankhira nsonga kupyola kabowo kakang'ono komwe kuli kumapeto kwa chotengera choyezera.

Mukufuna kufunsa ngati kuli kofunikira kulumikiza waya wapansi. Mukamagwiritsa ntchito oscilloscope mumayendedwe amagetsi, ndikofunikira kulumikiza nthaka ya oscilloscope ku gwero lapansi lolumikizidwa ndi nthaka. Izi ndi kuteteza kuopsa kwa magetsi ndi kuwonongeka kwa dera.

Komabe, kulumikiza waya wapansi sikofunikira kuti muwunikenso. 

8. Konzani funde

Ngati mawonekedwe a square wave sakukwanira pa sikirini, mutha kusintha nthawi zonse pogwiritsa ntchito TIME/DIV ndi VOLTS/DIV zowongolera. 

Zowongolera zina zothandiza zikuphatikiza zowongolera za Y-POS ndi X-POS. Ngakhale kuwongolera kwa Y-POS kumathandizira pakati pamapindikira mopingasa, X-POS imayika m'mbali mwake molunjika.

Tsopano mutha kugwiritsa ntchito oscilloscope kuyeza ma siginecha amagetsi ndikupeza zotsatira zolondola. 

Chifukwa chiyani ndiyenera kuyang'anira oscilloscope yanga?

Inde, muyenera kuwongolera oscilloscope. Mofanana ndi zida zina zamagetsi, kuwongolera oscilloscope kumathandiza kuonetsetsa kuti ikukwaniritsa miyezo yovomerezeka komanso kuti zotsatira zake ndi za mainjiniya ndi asayansi ena. 

Chifukwa chake, onetsetsani kuti oscilloscope yanu ndiyokhazikika poyang'ana pafupipafupi. Izi zipangitsa zotsatira zanu zoyezetsa kukhala zodalirika ndikukupatsani chidaliro mukamayesa ndi chida. Makamaka mukamagwiritsa ntchito oscilloscope pamawu, zosintha zonse ziyenera kukhala zolondola.

Kodi ma oscilloscopes ayenera kusanjidwa kangati?

Kuchuluka kwa oscilloscope calibration kumadalira mtundu wa oscilloscope womwe muli nawo. Komabe, nthawi yovomerezeka yovomerezeka ndi miyezi 12.

Ngakhale izi zingasiyane malinga ndi mtundu ndi chitsanzo cha oscilloscope, malo oyesera amathandizanso kuti oscilloscope awerengedwe kangati. 

Chifukwa chake, mukufuna kuwunika malo anu oyeserera kuti muwone momwe zimakhudzira kulondola kwa oscilloscope yanu.

Zinthu zambiri zimayambitsa zotsatira zolakwika ndi oscilloscope. Mwachitsanzo, zinthu monga chinyezi chochuluka, kugwedezeka, kusintha kwa kutentha, ndi fumbi zingakhudze kulondola kwa oscilloscope, kufupikitsa nthawi ya calibration. Komanso

Izi zikunenedwa, mukufuna kutsata zotsatira zanu ndikuwona ngati zili zolondola. Zotsatira za mayeso anu zomwe zimasiyana ndi zotsatira zokhazikika ndizozindikilo zokwanira kuti chida chanu chikuyenera kusanjidwa, mosasamala kanthu kuti mudachiyeza liti.
