Maitiro ekusarudza yakanaka oscilloscope yekubatanidza kuPC yako

Kusarudza kuti ndeipi oscilloscope yekutenga kuti ubatanidze kuPC mubvunzo wakajairika pakati pevanofarira zvemagetsi uye nyanzvi.Kupfuura mhando dzemunhu uye kurudziro, kune akati wandei ehunyanzvi zvinhu zvinogona kuita mutsauko pakati pekutenga zvine hungwaru nemidziyo inozove isingakwane kumapurojekiti ako. Naizvozvo, tichaputsa zvese zvine chekuita nekuita sarudzo ine ruzivo, tichitora mukana weruzivo rwechizvino-zvino uye rwakakwana.

Izvo hazvina basa kana iwe uri mudzidzi, nyanzvi yekugadzirisa, injinjini kana kungofarira zvemagetsi kugadzirisa.Mumitsetse inotevera, iwe unonzwisisa zvaunofanira kutarisa-uye nei-usati washandisa mari yako, uyewo ndeapi mamodheru ari kutungamira pamusika. Ini zvakare ndichakurukura zvakanakira USB oscilloscopes pamusoro pechinyakare uye maitiro ekutora mukana wekombuta yavo yekubatanidza kuwana zvakanyanya kubva pachiyero chimwe nechimwe.

Chii chaizvo chinonzi PC oscilloscope uye nei uchisarudza USB imwe?

Iyo oscilloscope chishandiso chakakosha mumagetsi. Inokubvumira kuti uone kuti chiratidzo chemagetsi chinosiyana sei mukati el tiempo, zvichiita kuti zvive nyore kuwana matambudziko, kuongorora maitiro edunhu, uye kududzira ruzivo rusingabviri kuwana neyakajairwa multimeter. Mienzaniso yakagadzirirwa kushandiswa nekombiyuta inowanzo USB oscilloscopes, izvo zvinoreva mabhenefiti maviri: iwo akanyanya compact, malaptop uye zvehupfumi, uye tora mukana wePC yako skrini uye zviwanikwa kuratidza uye kuongorora masaini.

Sei USB mhando dzakakurumbira zvakadaro? Nekuti software yayo inobvumira kuongororwa kwepamberi, kuchengetwa kwehuwandu hwe data, uye inoshanduka inoshanduka pane yakajairwa michina.

Mabhenefiti makuru e USB oscilloscope

• Portability uye kunyaradza: Saizi yavo yecompact inokutendera kuti uvashandise chero kupi: iwe unongoda laptop yako uye chiridzwa pachacho, pasina kuenderana neyakazvitsaurira skrini.
• Kukosha kwemari: Iwo ane hupfumi zvakanyanya kupfuura echinyakare desktop makomputa, zvichiita kuti zvive nyore kuwanikwa nevadzidzi uye madiki marabhoritari.
• Unyanzvi hwe kuchengetedza: Kutenda kune dhiraivha yekombuta yako, unogona kuchengetedza kurekodha kwenguva refu uye kuongorora masaini akaomesesa pasina kunetseka pamusoro pemiganho yemuviri yemukati mendangariro yemudziyo.
• Yepamberi software: Ivo havangoratidzi chiratidzo chete, asi zvakare vanobvumira kuongororwa kwemasvomhu, kuchengetedza data uye kutumira kunze, chizvarwa chemushumo, kutora chiitiko, uye, kazhinji, maitiro ekugadzirisa kuburikidza nesoftware.

Zvinhu zvakakosha pakusarudza yakanaka PC oscilloscope

Chakavanzika chekutenga chakakodzera kuziva uye kuenzanisa izvo zvakakosha chaizvo.Pazasi iwe uchadzidza zvakadzama zvinhu zvausingafanire kufuratira zvichienderana nekushandiswa kwaunoronga kuzvipa.

1. Bandwidth

Iyo bandwidth inosarudza iyo yakawanda frequency iyo oscilloscope inogona kunyatso kuyera.Kana iwe ukashanda ne-high-speed zviratidzo (microcontrollers, mabhasi edhijitari, zviratidzo zveanalog zvinokurumidza), unoda muenzaniso une bandwidth inonyatso pfuura kuwanda kwehuwandu hwezviratidzo zvako.

Kurudziro inoshanda: Kuongororwa kwemagetsi epamba, kugadziriswa kweTV, odhiyo, kana zvakafanana, bandwidth ye60-100 MHz inowanzokwana. Kune mamwe mapurojekiti ehunyanzvi (kutaurirana, RF, advanced digital system), funga mamodheru ane 200 MHz kana kupfuura. Mamodeli evadzidzi vekutanga anowanzo kupa 60-100 MHz, kunyangwe mamwe mamodheru epamberi anosvika pakakwirira.

2. Sampling rate

Muyero wesampling unoratidza kuti masampuli mangani pasekondi iyo oscilloscope inogona kutora.Kana iri yakaderera, iwe unorasikirwa neruzivo mumasiginecha anofamba nekukurumidza: iwe unofanirwa kunanga chiyero chesampling 2,5-4 nguva yechiratidzo bandwidth. Nyanzvi dzinopa zano kuti iyo yakakwira chiyero chesampling, iyo yakanyanya kutendeka kubereka kwechiratidzo kuchava uye kudzikisa kukanganisa.

Semuenzaniso, kana chiratidzo chako chekukurumidza chiri 20 MHz, oscilloscope inofanira kuenzanisa 80-100 MS/s (mega samples pasekondi).

3. Kudzama kwendangariro

Memory kudzika kunotsanangura kuti mapi mapoinzi iyo oscilloscope inogona kuchengeta mune imwe data kubatwa.Iyo yakakura kudzika, iyo yakakura kugona kuswedera mukati uye kuongorora zvakadzama mumasaini marefu.

Kuongorora zviitiko zvenguva refu kana kuisa mamaki pane chaiyo zviitiko mukati mechiratidzo chakareba, kudzika kwendangariro kwakakosha. Kana ndangariro dzakaganhurirwa, hauzokwanisi kuongorora masaini zvakadzama kana uchiswededza mukati pakubata.

4. Nhamba yenzira

Huwandu hwemachaneli hunotaridza kuti mangani masaini aunogona kuyera panguva imwe chete.PC oscilloscopes inowanzopa 2 kana 4 migero, kunyange zvazvo mienzaniso yepamusoro inogona kukwira kusvika ku 16. Pazvikumbiro zvakawanda, 2 migero inokwana, asi kana uchida kuenzanisa zviratidzo zvakawanda panguva imwe chete, tsvaga mhando dzine 4 kana kupfuura.

Ramba uchifunga kuti kana machanera mazhinji aunawo, anowedzera kudhura uye kuwanda kwemidziyo.

Iyo Trigger System: Kutora Makiyi Zviitiko

Iyo trigger system yakakosha kutora zviitiko zvakananga muchiratidzoIzvo zvinonyanya kukonzeresa zvinokonzeresa (kana chiratidzo chinokwira kana kuwira pasi pehumwe kukosha), asi zvishandiso zvemazuva ano zvinopa zvinokonzeresa zvinoenderana nehurefu hwenguva, logic level, maprotocol, uye zvimwe zviitiko zvepamberi.

Iyo yakanaka yekukonzeresa sisitimu inobatsira kuderedza nguva yekuongorora, kusefa kunze ruzha, uye kutarisa chete pane zvine basa. Iwo achangoburwa modhi anosanganisira inogadziriswa hysteresis uye inoteedzana inokonzeresa sarudzo, zvichiita kuti zvive nyore kutora chaiwo zviitiko kana anomalies mumasaini akaomarara.

Zvimwe zvakakosha zvekuwedzera maficha

Software kugarisana uye simba

Hunhu uye kushanda kwesoftware inoperekedza USB oscilloscopes inosiyana zvakanyanya.. Tsvaga intuitive zvirongwa zvinoenderana neako yekushandisa system (Windows, macOS, Linux) uye izvo zvinobvumira kuongorora kwepamusoro-zoom, spectral ongororo, kuyerwa otomatiki, kutumira kunze data, mishumo, graphical chengetedzo - kushandisa zvakanyanya chishandiso.

Hunhu uye zvakasiyana-siyana zveprobes

Iyo oscilloscope uye maprobes ayo anoumba mubatanidzwa wekuyera system.Maprobe emhando yakaderera kana maprobe asina kukwana bandwidth anogona kudzikisira kuita kweoscilloscope yako, kunyangwe iri hombe oscilloscope. Gara uchisarudza 10x passive probes yezviyero-zvinangwa zvakawanda, uye funga mutsauko kana high-voltage probes, zvichienderana nerudzi rweyedzo yauri kuita.

Musiyano pakati peanalog uye digital oscilloscopes

Mazuvano, akawanda maPC-anobatika modhi ndeyedhijitari..

• Analog: Ivo vanoratidza chiratidzo munguva chaiyo, yakanakira kutariswa kwakananga, asi pasina kurekodha kana epamberi kuongorora mabasa.
• digitaalinen: Ivo vanoshandura chiratidzo cheanalog kuita chiratidzo chedhijitari uye vanobvumira kuongororwa kwemasvomhu, kuchengetedza, zoom, kubvisa ruzha uye mamwe mabasa.

Ramangwana nderedhijitari, kunyanya kana iwe uchida kutora mukana wesoftware uye PC yekubatanidza.

Yepamberi maficha uye ekuwedzera emazuva ano USB oscilloscopes

Pamusoro peiyo basic specifications, Mhando dzazvino dzinosanganisira mabasa anobatsira:

• Kuchengeta uye kuenzanisa waveforms
• Panguva imwe chete kuratidzwa kwemasaini akawanda
• Protocol analysis (I2C, SPI, UART, CAN…)
• Export mumhando dzakasiyana
• FFT (Fast Fourier Shanduko) Ongororo
• Detailed zoom uye chiratidzo editing
• Multi-color displays kuti zvive nyore kuzivikanwa
• Portability uye bhatiri simba kubva kuPC

Inoratidzwa mhando dze USB oscilloscopes yekubatanidza kuPC

Rondedzero inotevera inopa yakanakisa-yakatemerwa uye yakanyanya kukurudzirwa michina yemaprofile akasiyana:

Zano rinoshanda usati watenga

Usati wasarudza, Nyatsoongorora iyo huru yekushandisa uye masaini auri kuyeraKana zviri zvemabasa ekutanga chete kana kushandiswa apo neapo, koshesa kureruka uye mutengo wakaderera. Kuti uwedzere kuchinjika uye kuita, dyara mune yakakwira bandwidth, mareti emuenzaniso, uye sarudzo dzepamberi dzekukonzeresa. Tarisa kuenderana nesoftware yako uye komputa.

Izvo zvakakoshawo kusimbisa kuti mugadziri anopa rutsigiro, zvigadziriso, uye kuwanikwa kwezvikamu zvakasara (senge probes uye tambo).

Kusarudza iyo oscilloscope chaiyo yekubatanidza kuPC yako kunoda kuongorora tekinoroji zvinhu-senge bandwidth, sampuli mwero, ndangariro, uye chiteshi-uye kuzvibatanidza nezvako chaizvo zvaunoda. Mutengo-kuita reshiyo, maficha esoftware, uye tsigiro yehunyanzvi ndiyo kiyi yekuve nechishandiso chinogoneka uye chakavimbika, kubva kumapurojekiti eamateur kuenda kune nyanzvi yekushandisa.
