Koma pali chida chimodzi choyesera chomwe sichimawonedwa nthawi zambiri monga kale, ndipo ndizochititsa manyazi chifukwa ndi chida chosinthika kwambiri.Zoonadi, ngati simugwira ntchito ndi opanda zingwe, mwina sizikhala pa mndandanda wazomwe mukufuna, koma ngati muchita chilichonse ndi RF, si chida chosunthika chokha, komanso chofunikira kwambiri.zimatchedwa chiyani.M'mbuyomu ankatchedwa "Grid Dip Oscillator" kapena GDO.Nthawi zina mumatha kuyimva ikutchedwa "grid tilt mita".Komabe, matembenuzidwe amakono alibe machubu (ndipo chifukwa chake ma grates), ndichifukwa chake nthawi zina mumawamva tsopano akutchedwa inclinometers, kapena mwina ndowa.
Chilichonse chomwe mumawatcha, mfundo ya ntchito ndi yofanana, ndipo ndi yosavuta.Chidachi sichinthu choposa oscillator yotambalala kwambiri yokhala ndi zotulutsa zomwe zimalumikizidwa ndi dera lakunja.Palinso njira zowongolera kuchuluka kwa mphamvu zomwe jenereta ikugwiritsira ntchito.Izi nthawi zambiri zimachitika poyang'ana nsonga ya matalikidwe a oscillator.
Chifukwa cha kutsika chikugwirizana ndi momwe inductor ndi capacitor zimachitira pamayendedwe osiyanasiyana.Pali magwero atatu a impedance pafupifupi pafupifupi dera lililonse kapena chigawo chilichonse: kukana, zomwe siziyenera kusintha pafupipafupi, capacitive reactance, chifukwa cha capacitance, ndi inductive reactance of inductive components.Nthawi zina, muli ndi zambiri.Mwachitsanzo, zoletsa kaboni siziyenera kukhala ndi mawonekedwe ochulukirapo amtundu uliwonse.Ma capacitors ayenera kukhala olimba kwambiri.
Kwa capacitor yomwe wapatsidwa, mayamwidwe ake ndi akulu kwambiri pama frequency otsika komanso ochepa kwambiri pama frequency apamwamba.Inductance imachita mosiyana: ma frequency otsika amatulutsa ma frequency ochepa kuposa ma frequency apamwamba.Izi ndizosavuta kukumbukira ngati muganiza za mafunde achindunji ngati mafunde a zero hertz.Inductor (coil) mwachiwonekere idzanyamula DC (otsika reactance), pamene capacitor (mbale ziwiri zofanana) mwachiwonekere sichidzanyamula DC (high reactance).
Ngakhale kukana kwathunthu kwa dera kumadalira zinthu zitatuzi, sizophweka monga kuwonjezera zikhalidwe.Izi zili choncho chifukwa kukana ndi kuchitapo kanthu sikufanana kuchuluka.Ngati muli ndi siginecha ya 1V ikupita ku katundu wa 2 ohm wokhala ndi 3 ohm reactance, mukufuna kudziwa kuti imachita chimodzimodzi ndi 1V kupita ku chopinga chokhazikika.Ngati kukana ndi kuchitapo kanthu kumalumikizidwa mu mndandanda, mtengo wa kukana kogwira mtima uku ndi wofanana ndi impedance, yomwe ndi chiwerengero cha vector of resistance and reactance.
Chifukwa chake mu chitsanzo ichi 22+32=13.Mizu yayikulu ya 13 ndi ndendende 3.6, kotero kuti cholepheretsa ndi 3.6 ohms.Pofuna kusokoneza zinthu, kuchititsa chidwi ndi capacitive reactance kumakonda kuletsana.Capacitive reactance nthawi zambiri imawonedwa ngati yolakwika, ngakhale popeza tikuyimitsa, zilibe kanthu kuti mumaganizira zamtundu wanji wotsutsa pakuwerengera uku.Kwa iwo omwe amakonda masamu, mumaganiza zotsutsa ngati gawo lenileni ndikuchitapo kanthu ngati gawo lolingalira la nambala yovuta.Kutembenukira ku mawonekedwe a polar kumapereka kukula ndi mbali.
Kulumikizana kofananirako kumakhala kofanana, koma kukhudzidwa kumawonjezeka mofanana ndi otsutsa ofanana.Koma chowonadi ndichakuti pama frequency ena, inductive ndi capacitive reactance ndizofanana.M'magawo angapo, izi zikutanthauza kuti zomwe zimachitika zimakhala zero ndipo kukana kumatsalira.Mu dera lofananira, zero zimathera mu denominator ya kagawo kakang'ono, kotero kuti kuyankhidwa kogwira mtima kumakhala kopanda malire (ndipo pamene chopinga choyera chikugwirizanitsidwa mofanana, sichimasintha mtengo wa resistor).Mulimonse momwe zingakhalire, zomwe zimachitika zimasiya, ndikusiya kukana koyera.
Mfundo yomwe imasiyanitsidwa imatchedwa resonance.Inclinometer imagwira ntchito chifukwa pa resonance point, oscillator ya mita idzawona katundu wambiri (otsika kwambiri) kotero kuti magetsi adzagwa (kapena kutsika).Nthawi zina, kukhudzidwa kwina kumakhalabe ndipo kusokoneza konse kwa dera lomwe likuyesedwa kudzakhala kokwera kuposa pa resonance.
Mwachiwonekere, ntchito yayikulu ya inclinometer ndikuyesa ma frequency a resonant a dera.Ngati ndizo zonse zomwe zimafunika, ndizothandiza kwambiri.Koma ndi kuyesetsa pang'ono, inclinometer imatha kuchita zambiri.
Choyamba, imatha kuyezanso mabwalo ena osinthidwa, osati ma capacitor ndi ma inductors okha.Mwachitsanzo, tinyanga, makhiristo, ndi mizere yopatsirana imatha kukhala ndi nsonga yake, ndipo mita imatha kuyeza.Kwa makhiristo, ma frequency ndi ma oscillation pafupipafupi a kristalo (ndi zolakwika zina kutengera kuchuluka kwa katundu ndi zinthu zina).Tinyanga tating'ono ting'onoting'ono zimatha kumveka ma frequency angapo, osati zomwe mukufuna, chifukwa chake pamafunika kuweruza.Chilichonse chomwe chilibe koyilo (monga mlongoti kapena kristalo) chimafunika koyilo yaing'ono kuti isamutse mphamvu kuchokera pa mita kupita kudera.
Pazingwe zamagetsi, mutha kuyeza izi popanga chipika chaching'ono kuti mulumikizane ndi inclinometer (yaing'ono bwino).Pezani dip yotsika kwambiri ndipo iwonetsa 1/4 wavelength ya pafupipafupi kufala kwa mzere.Mwachitsanzo, ngati chingwe chimamveka pa 7.5 MHz (mamita 40 kutalika kwa mawonekedwe), chingwecho chimakhala chautali wa mamita 10.Komabe, musaiwale kuganizira kufala mzere liwiro factor.Ndiko kuti, mzere wotumizira wa kotala-wave wokhala ndi chiwopsezo cha 0,66 udzakhala wamfupi kuposa kutalika kwamalingaliro (panthawiyi, ndi 66% yokha yautali wamalingaliro).
Zachidziwikire, mutha kugwiritsa ntchito mizere yopatsirana momwe mungakonde.Ndiko kuti, mutha kupeza ma frequency a resonant kuyeza chingwe, kapena mutha kukhazikitsa ma frequency ndikusintha mzere wotsetsereka.M'malo mwake, kugwiritsa ntchito zomwe mukudziwa kuti mupeze zomwe simukuzidziwa nthawi zambiri ndi mfundo yabwino yama grid inclinometers.Mukufuna kuyeza capacitor yosadziwika?Pangani kuti ikhale yomveka ndi inductor yodziwika.Kapena yambani ndi capacitor yodziwika ndikupeza mtengo wa koyilo yosadziwika.
Komabe, vuto limodzi lalikulu ndikuwerenga pafupipafupi molondola.Masensa ena amakono amakhala ndi zowonera zama digito (monga DipIt yomwe ili kumanja).Komabe, zoyezera zodziwika bwino sizitero.Kumbali inayi, mutha kuwalumikiza mosavuta ku mita yafupipafupi kapena kugwiritsa ntchito cholandila kuti muwone bwino ma frequency.
Miyezo yambiri ilipo ngati simusamala kuyerekeza.Ma coils ali ndi Q (Q factor) omwe amawonetsa kukana kwawo kutengera momwe amachitira.Gwiritsani ntchito capacitor yabwino, pangani dera lozungulira ndikuzungulira mita.Samalani pafupipafupi.Kenako tsitsani inclinometer mpaka mutazindikira kuti kuwerenga kwake kuli pafupifupi 30% kuposa komwe kumapendekeka.Tsopano kwezani sensa yopendekera ndikutsikanso potsetsereka mpaka mutapezanso chizindikiro cha 30% mbali inayo.Q ili pafupifupi yofanana ndi ma frequency otsika omwe amagawidwa ndi kusiyana pakati pa ma frequency awiri a 30%.
Izi zitha kuwonekera, koma Ursa Major atha kugwiritsidwanso ntchito ngati gwero lazizindikiro.Mwachitsanzo, kuti mukonzere wailesi, muyenera kuyika inclinometer kufupi ndi nthawi yomwe mukufuna kuti wailesiyo imve ndikuyiyang'anira kuzungulira dera.Ma inclinometer ambiri amakhalanso ndi njira yomwe amazimitsa oscillator ndikugwiritsa ntchito koyilo (ndi tuning capacitor) ndi diode ngati mita ya kutalika kwa mafunde.Kenako mita imawonetsa mulingo wa mphamvu ya RF pama frequency osinthidwa.Masensa ena amakhala ndi ma jacks am'mutu kuti mutha kumvera chizindikirocho (kupangitsa kuti ikhale ngati wailesi ya kristalo).
Chimodzi mwa zifukwa zomwe anthu ambiri alibe ma inclinometer masiku ano ndi chakuti sakupezeka mosavuta monga momwe ankakhalira kale.Heathkit ndiwotchuka kwambiri wogulitsa ma inclinometers amitundu yosiyanasiyana.Mitundu ina yotchuka ya mpesa (yomwe nthawi zambiri imawonedwa pa eBay) ndi Eico, Millen, Boonton, ndi Measurements Corporation (samalani, ngati simuli wokhometsa, zitsanzo zamachubu sizingakhale zopindulitsa kwambiri).Mutha kupeza mndandanda wazithunzi zambiri za GDO patsamba la [n4xy] (zithunzizo ndizongodina pang'ono kuchokera pa batani lotsatira patsamba lalikulu).Kumanzere kuli chithunzi cha Miyeso yanga yakale ya GDO (ndipo inde, imagwiritsa ntchito machubu).
Mutha kupezabe ma inclinometers atsopano kuchokera ku MFJ (amagulitsa MFJ-201 yomwe ikuwonetsedwa kumanja ndipo mutha kusinthanso ena mwa zowunikira zawo za mlongoti kukhala ma inclinometers ogwirika).Palinso mapulogalamu ambiri pa intaneti.Ngati mukufuna mod yeniyeni ya chubu (yosavomerezeka), [w4cwg] ili ndi mapulani.[SMOVPO] imabweretsa mapangidwe amakono a FET okhala ndi chodumpha chatsopano chothandizira kutsika kwambiri.
Kumbali ina, zikuwoneka zamanyazi kupanga gawo latsopano popanda chiwonetsero cha digito.Zachidziwikire, mutha kuwonjezera imodzi, kapena kugwiritsa ntchito yomanga ngati DipIt kapena ELM.Palinso zinthu zina zambiri komanso zida.Yang'anani pozungulira.Mbali yovuta kwambiri nthawi zambiri imakhala yokhotakhota, ngakhale ena amafunikira ma capacitor osinthika omwe ndi ovuta kuwapeza.Komabe, pochita, oscillator aliyense yemwe angakhazikitsidwe adzachita.M'malo mwake, ndili ndi zidebe ziwiri zakale za Heathkit zomwe zimagwiritsa ntchito ma diode osakanikiza ngati ma oscillator (imodzi yomwe ili kumanzere).
