USB oscilloscope ngezandla zakho: isikimu, ukubuyekezwa

USB oscilloscopes zidalwe ezihlola uphawu lukagesi kulesi sifunda. Amamodeli asetshenziswa emikhakheni ehlukahlukene. Uma sicabangela ukuguqulwa olulodwa-siteshi, avame ukusetshenziswa ukuba zisetshenziselwe ukuhlola imishini. Ukuze ukulandelela imvamisa gigahertz awayona efanelekayo.

kudivayisi Amabili isiteshi esetshenziselwa ukuqapha oscillations kagesi. onobuhle yamanje ayatholakala nge Photowire. amadivaysi Three-isiteshi Site imvamisa cwaningo gigahertz. Ukuze uthole ukwaziswa okwengeziwe mayelana izikophu, kufanele ucabange isikimu imodeli ejwayelekile.

Isikimu oscilloscope elula

Kuvamile-USB oscilloscope (scheme kukhonjisiwe ngezansi) kuhlanganisa isamukeli kagesi kanye modulator. Extender is avame ukusetshenziswa inguquko. Capacitors asetshenziswa amadivayisi ngaphandle transistors. Uma sicabangela modulators ukuguqulwa ke babe pentode. Ukuze kuncishiswe voltage embundwini rectifier isetshenziswa. Okuhlungayo kuyakhiwa ukufakwa kumadivayisi dinistorov. Nozwela oscilloscope incike uhlobo transceiver.

imodeli Single-siteshi

I single-isiteshi oscilloscope USB kuyinto kahle kulula. Kulokhu, lo cathode ray tube efakwe kanye modulator wave. Ochwepheshe abaningi bathi element ongakulayisha iyadingeka ukuba microns elingekho ngaphezu kuka 10. Kubalulekile futhi ukusebenzisa tetrode ukunciphisa ukuzwela zedivayisi. Expander oscilloscope esikhethiwe okukhipha hlobo. Sepharamitha embundwini voltage timphawu iyadingeka ukuba 20 V

Imvamisa nokukhawulela we olwandisa yalolu hlobo ingeqi 130 Hz. Ukufaka kwesihlungi kuyodingeka usebenzise yensimbi nokunamathisela ngomthofu. I stabilizers asetshenziswa amamodeli kuyinto ngempela ezingavamile. Ukuze ukuxazulula izinkinga ne ukumelana landa ipuleti transducer ingasetshenziswa. Standard onomzali isiteshi oscilloscope umdwebo akuyona ngaphandle rectifier.

Isikimu kudivayisi bi

Ngosizo le dipole we modulator kungaba ezimbili isiteshi se-USB-oscilloscope ngezandla zabo. Idivayisi isifunda sihlanganisa iSifundazwe a cathode ray tube ne-amplifier. Uma sicabanga version standard, rectifier ayidingekile ukuyisebenzisa. Inzuzo enkulu imodeli kuphezulu nesilinganiso ukunemba kwayo.

Ukuze uxhume Transistor isethwe transceiver. Futhi, ezimbili isiteshi wesifunda-USB oscilloscope kuhlanganisa converters. Basuke ekhethelwe 20 noma 25 V. Uma sicabangela samuntu lokuqala, capacitors abavunyelwe ukusebenzisa uhlobo evulekile. Ukuze ufake Converter 25 e edingekayo izinga yokusebenza zokuhlunga. Ekupheleni isilawuli is agibele amahhashi. Lokukhipha oxhumana-USB port axhunyiwe nge transceiver.

Uphenyo izinguqulo ezintathu-siteshi

Laba bobathathu-siteshi-USB oscilloscope ifanelwe Izibuyekezo ezinhle kusuka kuzazi. Okokuqala kubalulekile ukuphawula ukuthi amadivayisi abanjalo bangabaphostoli ukufundwa olunembile kakhulu. I izinzwa bajwayele nge conductivity ezahlukene. Cathode ray tube, njengoba umthetho, isethelwe amplifier. ukulungiswa Abaningi kuya capacitors esetshenziswa ngaphandle kwezihlungi. Ukuze baxazulule izinkinga ngamandla yokwanda kwama usebenzisa rectifier ezivamile.

Uma ukholelwa ukuthi ochwepheshe, izinga yokumelana ongathandeki oscilloscope kumele singeqi 30 ohms. Futhi, ngaphambi kokushintsha ukuguqulwa eliqinisekisiwe ipharamitha embundwini voltage. Ukuze uthole isibonelo ilila akumele leqe 35 V. Ngenjongo ukufakwa ku model of the Transistor kuyinto contactor soldered. Amadivayisi amaningi asetshenziswa ngaphandle isilawuli.

Ukubuthanela 5

Nge contact olwandisa ungenza elula -USB oscilloscope ngezandla zabo. Idivayisi isifunda sihlanganisa iSifundazwe a cathode ray tube kanye modulator. Ukuze baxazulule izinkinga ukuminyana izihlungi ezisetshenziswa inethiwekhi. Isilawuli ngokuvamile akhethiwe wire hlobo. thyristor oludingekayo ukuze evamile ukusebenza capacitor. Ukuyifaka uzodinga ukusebenzisa yensimbi nokunamathisela ngomthofu.

Uma ukholelwa ukuthi Izibuyekezo ngochwepheshe, le analogue cluster kulesi simo kungcono hhayi ukuyisebenzisa. Kubalulekile futhi ukuqaphela ukuthi tetrode phakathi oscilloscope USB akumelwe ifakwe. Lena ngokuyinhloko ngenxa ukwanda kokutheleleka kudlange kakhulu ukumelana ezimbi. Libuye libe imodeli nalezi izakhi athatha ugesi. Ukulungiswa based broadband rectifiers awavamile. Ekupheleni komsebenzi kubalulekile ukulungisa oxhumana okukhiphayo. -USB semikhumbi yokuxhuma ngokuvamile efakwe ngokusebenzisa modulator.

Oscilloscopes-10

Isifunda we oscilloscope 10 kuhlanganisa ezimbili wire capacitor. Ukwakha imodeli kwasekuqaleni kubalulekile ukwenza ukufakwa tube cathode ray. Ukuze operation evamile inzwa isetshenziswa iyaguquka modulator. It efakwe kule oscilloscope USB ngokusebenzisa emazombezombe. Ezinye ukushintshwa ube thyristor. Uma ukholwa ukuthi umbono ochwepheshe ', ukuthi lezi onobuhle akuzona ukufundwa olunembile kakhulu. Kulokhu, kangcono ukukhetha izinga comparators.

zamanje conduction izinga izinto ezidingekayo ukuze kungabi ngaphansi kuka 6.2 microns. Sepharamitha embundwini nozwela oscilloscopes at 10 W emhlabeni 30 ohms. Isilinganiso yokusebenza imvamisa akuyona ezingaphezu kuka-130 Hz. Uma ukholelwa ukuthi Izibuyekezo ngochwepheshe, bese uxhumana izihlungi ayikwazi ukusetshenziswa. Okokuqala anika ukucindezeleka okuningi phezu capacitors. Kubalulekile futhi ukwazi ukuthi abakwazi ukuba sibhekane ngokuphumelelayo oscillations kagesi ngokugcwele.

Indlela yokwenza imodeli phezu 15 V?

Yenza i-USB oscilloscope kwikhompyutha 15 in a lula angabacwasi. Ukwakha imodeli usebenzisa ezivamile cathode ray tube. Nokho, kubalulekile ukuphawula ukuthi kunilungele ngaphezulu ukuze ukhethe modulator ne-adaptha. Emakethe umkhiqizo kukhona at 10 no-15 microns. Uma sicabanga ukhetho lokuqala, capacitors Kusetshenziswa thyristor.

Negative ukumelana sibalo kusukela oscilloscope esiphezulu 25 amamitha. Uma sicabangela version nge i-adaptha ukuze 15 microns, kungenzeka capacitors esetshenziswa uhlobo evulekile kuphela. Ukuze ulwe ukuphazamiseka kagesi kukhona amapuleti. amadivaysi Converter yalolu hlobo isicelo imvamisa low. Ukuze uthuthukise ukunemba nesilinganiso ukufundwa kukhona rectifiers esetshenziswa.

Ukusebenzisa uchungechunge resistors PPR1

Oscilloscopes nalezi resistors e baningi. Lezi zihlanganisa nokulungiswa kumadivayisi olulodwa-siteshi. Fit oscilloscopes kakhulu ngokuhlola zikagesi. Kubalulekile futhi ukuqaphela ebucayi kakhulu ukuthi bakuphi. Ukuze wenze imodeli eyabo, badinga cathode ray tube.

Kulokhu, lo isicelo ishayela uhlobo modulator. Uma ukholelwa ukuthi ukubuyekezwa abathengi, kuzuzisa ukukhetha contactors nge ebheke. Nokho, rectifier okubekwa phambi ufake nabo. Ukuze kahle ukubonisa izinkomba esetshenziswa valve tube. Kuze kube manje, idivayisi wathi ikhishwe ngokushesha futhi uhlobo wave.

Uma sicabanga ukhetho lokuqala, kudingeka ukwakha oscilloscope isilawuli. Ukulungiswa kuya kenotrons wave ivelakancane. Ukumelana imishini inketho ingeqi 33 ohms. isignali conduction inkomba onobuhle endiza eduze 4.5 microns. Kubalulekile futhi ukwazi ukuthi kungenzeka USB-port ixhunywe ngokusebenzisa modulator.

Uphenyo onobuhle resistors PPR3

Oscilloscopes nalezi resistors zinezikhathi sensitivity high. Kulokhu, lo modulators esetshenziswa conductivity ongaphakeme kuphela. Ngokuvamile, lo voltage okukhiphayo ukubeka kubo ingeqi 15 V. Isilinganiso isignali reducibility kuyinto 6 microns. Enhancers ohlotsheni amadivayisi ngiyibona akhethiwe. Ukuze ukuqoqa USB yabo oscilloscope badinga cathode ray tube. Ngemva kokulilungisa ibekwe modulator.

Expander liyadingeka kuzolungiswa eduze comparator. Ukuze ukuxazulula izinkinga nge imvamisa low we tetrode. Ngqo resistors ngaphandle ulwelwesi. Ekupheleni kwe-soldered-USB semikhumbi yokuxhuma imishini kunethiwekhi. Lapho yokwanda kwama udinga ukufaka i-isimame. Wathi idivayisi isebenze ngaphandle-amplifier. Ukunciphisa ukushisa kokushonelwa comparator isetshenziswa.
