USB oscilloscope ngezandla zenu; cebo, izigxeko

oscilloscopes USB zenzelwa umkhondo uphawu zombane kwisekethe. Iimfaniso asetyenziswa kwiinkalo ezahlukeneyo. Ukuba sicinga ukuguqulwa olunye-channel, badla kusetyenziswa izixhobo zokuhlola. Ukuze ukulandelela amaza gigahertz bathe ezifanelekileyo.

isixhobo channel-ezimbini esetyenziselwa esweni oscillations kagesi. uhle ngoku ziyafumaneka kunye Photowire. izixhobo siteshi-amathathu efanelekileyo ukuze frequency isifundo gigahertz. Ukuze ufumane inkcazelo engakumbi malunga ulise, kufuneka ucinge scheme yemodeli eqhelekileyo.

Scheme oscilloscope elula

Normal USB-oscilloscope (scheme eboniswe ngezantsi) iquka ngumamkeli magnetic kunye modulator. Extender amaninzi kusetyenziswa akutshintsho. Capacitors zisetyenziswa izixhobo ngaphandle transistors. Ukuba sicinga modulators ukuguqulwa, ngoko ke babe pentode. Ukwenzela ukunciphisa umbundu ke ombane le rectifier iyasetyenziswa. Amacebo okucoca zifakwa kwizixhobo dinistorov. Uvakalelo le oscilloscope kuxhomekeke kuhlobo transceiver.

imodeli-channel Single

I-single-channel oscilloscope USB, ilula. Kulo mzekelo, i cathode ray ityhubhu efakwe kunye modulator wave. Iingcali ezininzi zithi element of bandwidth kufuneka ukuba babe microns kungekho ngaphezulu kwe-10. Kubalulekile kwakhona ukuba usebenzise tetrode ekunciphiseni uvakalelo kwefowuni. Olwandisa oscilloscope for uhlobo yemveliso olukhethiweyo. umbundu Ipharamitha ombane le element kufuneka ukuba ibe 20 V.

Le rhoqo umda le olwandisa yolu didi ayidluli 130 Hz. Ukuze ufake lokucoca kuya kufuneka ukuba usebenzise zentsimbi ngelotha. Le ekwenzeni zisetyenziswa imifanekiso kakhulu inqabile. Ukusombulula iingxaki ebanceda uxhathiso nembasa transducer ingasetyenziswa. Standard single-channel oscilloscope umzobo ayikho ngaphandle rectifier.

Scheme device bi

Ngoncedo lwe dipole le modulator inokuba ijelo-ezimbini USB-oscilloscope ngezandla zabo. Icebo zeesekethe luquka a cathode ray ityhubhu kunye msindo. Ukuba sicinga kwinguqulelo esemgangathweni, i-rectifier akulindelekanga ukuba ukuyisebenzisa. Inzuzo ephambili Umfuziselo womlinganiselo accuracy yalo phezulu.

Ukuze uqhagamshele transistor ibekwe transceiver. Kwakhona, ijelo-ezimbini yesiphaluka USB-oscilloscope ibandakanya converters. Bona ezikhethiweyo 20 okanye 25 V. Xa siqwalasela ngobuwena yokuqala, capacitors bavumelekile ukuba basebenzise i hlobo evulekileyo. Ukuze ufake converter 25 ofunekayo filter yokusebenza esemgangathweni. Ekupheleni esisebenza imvelaphi inyuselwa khona. nabo Isiphumo ne USB-nezibuko elidityaniswe nge transceiver.

Ukuphonononga ye iinguqulelo channel-amathathu

Ijelo-amathathu USB-oscilloscope ifanelwe ncomo elungileyo kwiingcaphephe. Okokuqala kubalulekile ukuqaphela ukuba izixhobo ezinjalo Ufundo echanekileyo kakhulu. Nabenzi boluvo zisetyenziswa kunye conductivity ezahlukeneyo. Cathode ray tube, njengokuba umthetho, kulindeleke ukuba lo mshini. Izilungiso ezininzi ukuya capacitors kusetyenziswa ngaphandle izihluzi. Ngeenjongo zokusombulula iingxaki kunye yokwanda ngamandla usebenzisa rectifier oluqhelekileyo.

Ukuba uyakholwa iingcaphephe, izinga uxhathiso ezigxekayo le oscilloscope mayingagqithi ohms-30. Kwakhona, ngaphambi masicime ukulungiswa uqinisekise parameter threshold ombane. Enzelwe indlela elula oko kufuneka ngaphezulu 35 V. Ngenjongo ufakelo imodeli transistor yi lwekontraka soldered. amacebo amaninzi asetyenziswa ngaphandle isilawuli.

Ukuhlanganisana 5

Nge olwandisa zoqhagamshelwano ungenza elula USB-oscilloscope ngezandla zabo. Icebo zeesekethe luquka cathode ray ityhubhu kunye modulator. Ngeenjongo zokusombulula iingxaki ukuxinana amacebo asetyenziswa kwi-network. Le isilawuli rhoqo zohlobo olukhethiweyo wire. thyristor eziyimfuneko ukulungiselela umsebenzi capacitor yesiqhelo. Ukufakela kuya kufuneka ukuba usebenzise zentsimbi ngelotha.

Ukuba uyakholwa nokubuyekezwa ziingcali, i-analogue ezisebenzisanayo kule meko ke kungcono ukuba ukuyisebenzisa. Kubalulekile ukuba uqaphele ukuba tetrode kulo oscilloscope USB kufuneka ifakwe. Oku kubangelwa ikakhulu ekunyukeni elibukhali resistance negative. Kananjalo imodeli nezi zinto kudla umbane omninzi. Ukulungiswa rectifiers broadband esekelwe zinqabile. Ekupheleni yomsebenzi kubalulekile ukulungisa abafowunelwa kwimveliso. USB-izibuko loqhakamshelwano kakhulu ngokuqhelekileyo efakwe ngokusebenzisa modulator.

Oscilloscopes ku 10

Isekethi oscilloscope 10 kuquka ezimbini ucingo capacitor. Ukwakha imodeli kwindawo yokuqala kubalulekile ukwenza ufakelo ityhubhu cathode ray. Kuba ukusebenza okuqhelekileyo woluvo isetyenziswa modulator yenguqu. It efakwe kwi oscilloscope USB ngokusebenzisa jiko. Ezinye iinguqulelo babe thyristor. Ukuba uyakholwa uluvo ziingcali, ukuba le mizekelo na Ufundo kakuhle kakhulu. Kulo mzekelo, kungcono ukuba ukhethe comparators esemgangathweni.

izinga Uhanjiso ngoku izinto ekufuneka ukuba ungabi ngaphantsi kwe-6.2 microns. umbundu Ipharamitha ubuntununtunu of oscilloscopes 10 W ngeenxa 30 ohms. I-avareji rhoqo yokusebenza ayikho ngaphezu kwe-130 Hz. Ukuba uyakholwa nokubuyekezwa ziingcali, ayikwazi buzakusetyenziswa ngokwazisa le okucoca. Okokuqala bonke banikela uxinezeleko ngakumbi phezu capacitors. Kubalulekile ukuba uqaphele ukuba nako ukumelana oscillations kagesi ngokupheleleyo.

Indlela ukwenza imodeli ngomhla we-15 V?

Yenza USB-oscilloscope kwi computer 15 lula noko. Ukwakha imodeli usebenzisa eqhelekileyo cathode ray ityhubhu. Nangona kunjalo, kubalulekile ukuqaphela ukuba kusilungele, ngakumbi ukuba ukhethe modulator ne-adaptha. Kwi market imveliso ye ezihleli microns-10 no-15. Ukuba sicinga ukhetho yokuqala, capacitors zisetyenziswa kunye thyristor.

figure nokumelana embi oscilloscope iphezulu yi-25 eemitha. Xa siqwalasela nguqulo ne-adaptha ngenxa microns-15, le capacitors ingasetyenziselwa uhlobo ivuleleke kuphela. Ukuphelisa uphazamiseko magnetic le amacwecwe. Izixhobo Converter lo hlobo isicelo njalo. Ukuphucula ukuchaneka ufundo Kulinganiselo rectifiers babesebenzisa.

Ukusebenzisa uthotho resistors PPR1

Oscilloscopes nala resistors kukho imfuneko yayo eninzi. Ezi ziquka ulungiso izixhobo single-channel. Fit oscilloscopes ezininzi uvavanyo izixhobo zombane. Kubalulekile ukuba uqaphele ukuba ethe-ethe kakhulu. Ukuze wenze imodeli yabo, kufuneka cathode ray tube.

Kulo mzekelo, uhlobo ukubetha modulator isicelo. Ukuba uyakholwa nokubuyekezwa labathengi, kunilungele ukuba ukhethe contactors kunye bobuso. Nangona kunjalo, lo rectifier into ebekwa phambi kwenu uzifakelele. Ukuze ukubonisa ngokuchanekileyo Yayibubungqina ezisetyenzisiweyo valve ityhubhu. Ukuza kuthi ga ngoku, isixhobo kuthethwa ngokukhawuleza akhululwe kwaye nohlobo otshangatshangiswayo.

Ukuba sicinga ukhetho yokuqala, kufuneka ukwakha oscilloscope esisebenza. Ukulungiswa ukuya kenotrons otshangatshangiswayo ezinqabileyo kakhulu. elana izixhobo ukhetho awudluli ohms 33. uphawu Isalathisi Uhanjiso njengezibonelo endiza macala 4.5 microns. Kubalulekile ukuqaphela ukuba i-USB-izibuko ukuze elidityaniswe ngokusebenzisa modulator.

Kuvandlakanyo lwezikhokelo kunye resistors PPR3

Oscilloscopes nala resistors luphawulwa uvakalelo oluphezulu. Kulo mzekelo, i modulators kusetyenziswa kuphela conductivity eliphantsi. Ngokuqhelekileyo, le ombane output zibenze engaphenduli ngaphezulu 15 V. I-avareji reducibility Oluphawu microns 6. Ezifane izixhobo uhlobo uyibona zikhethiwe. Ukuze ukuqokelela eyakho USB oscilloscope yazo kufuneka ibe cathode ray tube. Emva ukulungisa ukuba ibekwe modulator.

Olwandisa kufuneka ukuba zibekwe kufutshane comparator. Ukusombulula iingxaki nge frequency esezantsi ye tetrode. Ngqo resistors zingenawo yethemba. Ekupheleni kwale soldered USB-izibuko loqhakamshelwano izixhobo kwinethiwekhi. Xa kwama kufuneka ufake i somfanekiso. Uthe isixhobo ongasebenza ngaphandle msindo. Ukunciphisa ilahleko ubushushu, kusetyenziswa le comparator.
