Ungaphambanisi i ama-generator amagagasi namanye amadivaysi esesivele sawabona kule bhulogi futhi angase abukeke afana kakhulu, njenge ama-oscilloscopes. Kulesi sihloko sizofunda ukuthi iyini i-wave generator, ukuthi ingasetshenziselwa ini kumaphrojekthi wethu we-electronics, indlela yokukhetha engcono kakhulu, njll.
Ukwengeza, ngizophinde ngibonise ezinye zazo the best wave generator esikuncomayo, ukuze ukwazi ukuthenga izinto zokusebenza ezivumelana nezidingo zakho...
Ama-generator amahle kakhulu we-wave
Ukuzuza the best wave generator, sincoma amadivaysi alandelayo elabhorethri yakho ye-electronics:
I-RIGOL DG1062Z Waveform/Function Generator
I-JUNTEK Isiginali Esiphathekayo Esihlelekayo Isijeneretha
Ayikho imikhiqizo etholakele.

Iyini i-wave generator noma i-generator yesignali?
Un i-wave generator, noma i-generator yesignali, Kuyidivayisi esetshenziswa ikakhulukazi ezindaweni zezimboni ekhiqiza isignali kagesi esesimweni samagagasi esingangeniswa kumjikelezo we-elekthronikhi ukuze yenze izinhlobo ezihlukene zokuhlola kanye nezinye izisetshenziswa zokuhlola zezimboni nezikali. Okusho ukuthi, ngenkathi amasiginali asuka kusekethe akalwa ku-oscilloscope, kujeneretha ajovwa kusekethe...
Ijeneretha yesiginali ingakhiqiza amagagasi aphindaphindayo nge izimo ezivamile ezifana nesikwele, i-pulse, sinusoidal, triangular, sawtooth, phakathi kwabanye. Enokusebenza emikhakheni eminingi, hhayi nje nge-elekthronikhi, kodwa nasezinhlelweni zikagesi.
Kubalulekile ukuqaphela ukuthi i-generator wave Ayinawo umsebenzi wokulinganisa isignali eyikhiqizayo, nakuba ungayibonisa. Umsebenzi wayo oyinhloko ukunika amandla noma ukuhlola amasekhethi kagesi noma ama-actuator ezindaweni zezimboni, noma amalabhorethri kagesi, ekuthuthukisweni nasekuqinisekiseni ukusebenza kwawo.
Njengoba ngishilo ngaphambili, ama-generator amagagasi asetshenziswa khiqiza amasignali ezikhathi ezithile, lapho i-voltage ishintsha khona ngezikhathi ezithile ngokuhamba kwesikhathi, ivumela isikhathi sayo (isikhathi se-oscillation ephelele) kanye ne-amplitude yayo (inani eliphezulu le-voltage yesignali) ukuthi ilawulwe. Kodwa-ke, ingadlala indima ebalulekile ekukhiqizeni amagagasi angewona awezikhathi ezithile.
Isetshenziswa kakhulu ku ukuklama, ukuhlola nokulungisa yemishini kagesi. Ngaphezu kwalokho, ingaba nezinhlelo zokusebenza zobuciko futhi isetshenziswe emkhakheni wezokwelapha. Namuhla, ngenxa yentuthuko eqhubekayo yobuchwepheshe, kukhona ama-generator amasignali athile emisebenzi ehlukahlukene. Lawa madivayisi angaxhunywa ngokuqondile kumakhompyutha futhi anikeze imisebenzi efana nokuloga kwamasignali akhiqiziwe kanye nekhono lokuhlela ijeneretha ukuthi ikhiphe ukulandelana okuthile kwamasignali.
Isetshenziselwa ini i-wave generator?
I-Las izicelo ezivamile Ama-generator amagagasi ahlukaniswe izigaba eziningana, okuhlanganisa:
- Ukunakekelwa kanye nesevisi yemishini yezimboni: Zisetshenziselwa ukwenza izivivinyo nokuxilongwa emishinini yezimboni, iqinisekisa ukusebenza kwayo ngendlela efanele.
- Ucwaningo nemfundo: Angamathuluzi abalulekile ezilungiselelweni zocwaningo nasezilungiselelweni zemfundo, lapho asetshenziselwa ukuhlola nemiboniso.
- Sebenzisa ensimini noma ezindaweni eziphephile: Amajeneretha esignali ayaphatheka futhi asetshenziswa ensimini noma ezindaweni lapho ukuphepha kudingeka khona, njengokuhlola ezindaweni ezilawulwayo.
- Ukukhiqiza okulula: Zibuye zisetshenziswe ezinhlelweni zokukhiqiza ezilula lapho amasignali athile adinga ukukhiqizwa ukuze kuhlolwe futhi kulinganiswe.
En imigomo yokusetshenziswa kanye nemisebenzi evamile ama-generator amagagasi angafingqwa ngezigaba ezintathu eziyinhloko:
- Ukudalwa kwesignali: Lawa madivayisi angakwazi ukukhiqiza amasignali kusukela ekuqaleni ukuze alingise, ashukumise futhi ahlole amasekhethi namadivayisi ahlukahlukene.
- Ukuphindaphinda Kwesiginali: Bangakwazi ukuphindaphinda amasignali, noma ngabe okudidayo, amaphutha noma amasiginali atholwe ama-oscilloscopes, elabhorethri ukuze alungise amapharamitha awo futhi awahlaziye endaweni elawulwayo.
- Ukukhiqizwa kwesignali: Asetshenziselwa ukukhiqiza amasignali afanelekile noma imisebenzi eyaziwayo esebenza njengereferensi noma okokufaka kokuhlolwa.
Ngaphezu kwalokho, ama-generator esignali anezinhlelo zokusebenza ezibalulekile ku imboni yezokuxhumana engenantambo kanye nomkhakha we-aerospace, lapho bengalingisa khona amasiginali njenge-radar noma i-GPS, noma bahlole izamukeli nezithumeli zedijithali.
Okubalulekile, amajeneretha amagagasi adlala indima ehlukile uma kuqhathaniswa nezinye izisetshenziswa zokuhlola nezikali zokulinganisa, njenge ama-spectrum analyzers, ama-multimeters nama-oscilloscopes. Ngenkathi lesi sakamuva sikala amasignali edijithali noma e-analog, ijeneretha ikhiqiza isignali lapho umsebenzisi ekhetha khona imvamisa ye-oscillation yegagasi...
Umehluko phakathi kwamajeneretha esignali namajeneretha okusebenza
Kungenzeka ukuthi wake wazibuza ukuthi ngabe lezi zinsimbi zombili ziyefana yini noma zinemehluko omkhulu, kahle, kokubili enye nenye inamandla okukhiqiza isignali eyethulwa kusekethe ukuze kubhekwe ukuziphatha kwayo, kodwa kukhona ukuhluka okumbalwa okuphawulekayo.
El Ijeneretha yomsebenzi inamandla okukhiqiza imisebenzi ejwayelekile echazwe ngaphambilini, njenge:
- I-Sine noma amagagasi e-sinusoidal.
- Izimpawu zesikwele.
- Umumo ongunxantathu.
- Izimpawu ze-TTL.
Isetshenziswa kakhulu ku ukulinganisa idivayisi ngomsindo, izinhlelo zokusebenza ze-ultrasonic kanye nezinhlelo ze-servo, ezisebenza ku-frequency range ye-0.2 Hz kuya ku-2 MHz. Nge-generator yomsebenzi, kungenzeka ukulawula umsebenzi wokushanela, ngaphakathi nangaphandle. Uchwepheshe uyakwazi ukulawula amapharamitha afana neleveli ye-DC offset, umjikelezo wokuskena, ububanzi nobubanzi, kanye nobukhulu besignali.
Nakuba ezicini ezithile zingase zibonakale zifana, azinakubhekwa njengezifana ngokuphelele. Kodwa-ke, ngenxa yentuthuko kwezobuchwepheshe, ama-generator amaza angakwazi ukukhiqiza izimpawu eziningi ebezihlotshaniswa kuphela ne-fun generator, okuholele ekutheni inhlanganisela imiqondo phakathi kwazo zombili izinhlobo zamathuluzi.
Izinhlobo zamajeneretha amagagasi
Kufanele wazi ukuthi yini engatholakala emakethe izinhlobo ezahlukahlukene zamajeneretha amaza noma amajeneretha esignali, enezici ezithile ezizihlukanisayo, kodwa okufanele futhi uzazi:
- I-Pulse generator: Le divayisi ingakwazi ukukhiqiza ama-pulses, okuhlanganisa ama-logic pulses anokulibaziseka okuguquguqukayo kanye nezinguquko zeleveli, okuwusizo ekuhloleni ukujikeleza kwedijithali, futhi ngezikhathi ezithile ezinhlelweni zokusebenza ezinengqondo. Ungathumela izitimela zama-pulses ukuze uvule izingxenye ezithile zesekhethi.
- Ijeneretha yomumo wesignali yomsindo: Idizayinelwe amaphrojekthi alalelwayo, isebenza kububanzi bemvamisa obungu-20 Hz ukuya ku-20 kHz. Kwezinye izimo, ingasetshenziswa futhi ukukhiqiza amaza e-sine namanye amaza omsindo.
- Ijeneretha ye-waveform engafanele: Lobu buchwepheshe obuthuthukisiwe buvumela ama-waveform angokwezifiso ukuthi akhiqizwe futhi aguqulwe ngezindlela eziyinkimbinkimbi. Nokho, lawa majeneretha ayabiza ngenxa yobunkimbinkimbi bawo futhi adinga ukukhawulela umkhawulokudonsa wawo. Ngaphambi kokuthenga eyodwa, kubalulekile ukucabangela ukusetshenziswa kwayo okuhlosiwe.
- Ijeneretha yesignali ye-RF (Radio Frequency): Njengoba igama layo liphakamisa, isebenza kububanzi befrikhwensi yomsakazo. Ingakhiqiza ukuguquguquka kwe-waveform, okufana ne-AM (Amplitude Modulated) noma i-FM (I-Frequency Modulated), futhi amamodeli athuthuke kakhulu angasebenza ngobuchwepheshe obufana ne-CDMA ne-OFDM, obuvamile kumadivayisi eselula. Kumasiginali we-analog, anikeza i-oscillation yamahhala futhi angasebenzisa amasu okukhiya ngezikhathi ezithile ukuze athuthukise ukuzinza kwesignali.
- Amajeneretha wesignali weVector: Lawa majeneretha afana namajeneretha e-RF, kodwa ayahluka ngekhono lawo lokusebenza ngamafomethi wokuguquguquka ayinkimbinkimbi, njenge-QAM (Quadrature Amplitude Modulation) ne-QPSK (Quadrature Phase Shift Keying). Ngakho-ke, asetshenziselwa ukuhlola amasistimu okuxhumana athuthukile, njenge-4G, 5G, nezinye izinhlelo ezifanayo.
- Ijeneretha yomsebenzi: Nakuba sesike sakhuluma ngamajeneretha asebenzayo, kubalulekile ukuwafaka lapha njengoba nawo ayisigaba samajeneretha esignali. Lawa madivayisi angakha amagagasi alula aphindaphindayo, njenge-sine, sawtooth, unxantathu, namagagasi ayisikwele. Nakuba amamodeli okuqala ayeyi-analog, awamanje ayidijithali, kodwa asengakwazi ukukhiqiza amagagasi aguqulelwe ku-analog. Abadingi ukusebenza ngamaza aphezulu ngenxa yohlobo lwamagagasi abawakhiqizayo, nakuba kukhona amamodeli angakwenza lokho.
