Tau txais ib qho oscilloscope siv los ua ib txoj hauv kev rau cov neeg nyiag khoom kho vajtse.Txog thaum tsis ntev los no, cov cuab yeej tshiab tsis tshua muaj nyob hauv tus neeg nruab nrab cov peev nyiaj, yog li koj tuaj yeem daig nrog oscilloscope qub.Muaj ntau cov kev xaiv pheej yig niaj hnub no, tshwj xeeb tshaj yog tias koj suav nrog pheej yig computer oscilloscopes thiab "oscilloscopes".Cov ntsuas hluav taws xob tseem pheej yig hnub no (lawv feem ntau pub dawb hauv qee lub khw muag khoom loj), xws li cov teeb liab generators, zaus counters, thiab txawm tias logic analyzers.

ASTM 201 304 Stainless hlau coiled tubing lwm tus neeg

Tab sis muaj ib qho khoom siv sim uas tsis pom ntau npaum li nws tau siv los ua, thiab qhov txaj muag vim nws yog ib qho khoom siv ntau yam.Kev lees paub, yog tias koj tsis ua haujlwm nrog wireless, tej zaum nws yuav tsis nyob hauv koj daim ntawv teev npe, tab sis yog tias koj ua ib yam dab tsi nrog RF, nws tsis yog ib qho khoom siv ntau yam, tab sis kuj tseem ceeb heev.nws hu ua nws nyob li cas.Keeb kwm lawv tau hu ua "Grid Dip Oscillator" lossis GDO.Tej zaum koj yuav hnov ​​​​nws hu ua "grid qaij meter".Txawm li cas los xij, cov qauv niaj hnub tsis muaj cov raj (thiab yog li grate), uas yog vim li cas qee zaum koj yuav hnov ​​​​lawv tam sim no hu ua inclinometers, lossis tej zaum tsuas yog thoob.
Txawm koj hu lawv li cas, lub hauv paus ntsiab lus ntawm kev ua haujlwm yog tib yam, thiab nws yooj yim heev.Qhov ntsuas tsis muaj dab tsi ntau tshaj li qhov broadband oscillator nrog cov zis txuas nrog rau sab nraud Circuit Court.Kuj tseem muaj txoj hauv kev los tswj lub tshuab hluav taws xob siv hluav taws xob ntau npaum li cas.Qhov no feem ntau yog ua los ntawm kev saib lub ncov amplitude ntawm oscillator.
Yog vim li cas rau qhov poob yuav ua li cas inductor thiab capacitor coj ntawm ntau zaus.Muaj peb qhov chaw ntawm impedance nyob rau hauv yuav luag txhua qhov hluav taws xob los yog cov khoom siv: kev tiv thaiv, uas yuav tsum tsis txhob hloov nrog zaus, capacitive reactance, vim qhov tseeb ntawm capacitance, thiab inductive reactance ntawm inductive Cheebtsam.Qee zaum, koj muaj ntau ntawm lawv.Piv txwv li, carbon resistors yuav tsum tsis txhob muaj ntau dhau reactance ntawm txhua yam.Capacitors yuav tsum yog feem ntau capacitive.
Rau ib tug muab capacitor, lub reactance yog loj heev ntawm tsawg zaus thiab tsawg heev ntawm high frequencies.Inductance ua qhov sib txawv: tsawg zaus tsim cov reactance tsawg dua cov zaus ntau dua.Qhov no yog ib qho yooj yim kom nco ntsoov yog tias koj xav txog tam sim no ncaj qha raws li nthwv dej nrog xoom hertz zaus.Ib qho inductor (coil) yuav pom tseeb nqa DC (tsis tshua muaj reactance), thaum lub capacitor (ob daim phiaj sib luag) yuav pom tseeb tsis nqa DC (siab reactance).
Txawm hais tias tag nrho cov kev tiv thaiv ntawm Circuit Court nyob ntawm peb lub ntsiab lus, nws tsis yooj yim li kev ntxiv cov nqi.Qhov no yog vim tsis kam thiab reactance tsis yog tib yam.Yog tias koj muaj lub teeb liab 1V mus rau hauv 2 ohm load nrog 3 ohm reactance, koj xav paub tias nws coj zoo ib yam li 1V mus rau hauv qhov tsis tu ncua.Yog hais tias tsis kam thiab reactance txuas nrog nyob rau hauv series, tus nqi ntawm qhov kev ua tau zoo no yog sib npaug rau impedance, uas yog vector sum ntawm kuj thiab reactance.
Yog li hauv qhov piv txwv no 22 + 32 = 13.Lub hauv paus square ntawm 13 yog raws nraim 3.6, yog li qhov impedance yog 3.6 ohms.Txhawm rau kom muaj teeb meem nyuaj ntxiv, inductive thiab capacitive reactance yuav thim ib leeg tawm.Capacitive reactance feem ntau suav hais tias yog qhov tsis zoo, txawm hais tias txij li peb tab tom squaring nws, nws tsis muaj teeb meem dab tsi ntawm qhov tsis zoo uas koj coj los rau hauv tus account rau qhov kev suav no.Rau cov neeg uas yog lej inclined, koj yeej xav txog qhov tsis kam ua qhov tseeb thiab reactance raws li qhov kev xav ntawm tus lej nyuaj.Hloov mus rau daim ntawv polar muab qhov loj thiab theem kaum.
Kev sib txuas ntawm qhov sib txuas yog hais txog tib yam, tab sis cov reactance nce nyob rau hauv tib txoj kev raws li qhov sib txuas resistors.Tab sis qhov tseeb yog tias ntawm qee zaus, inductive thiab capacitive reactance sib npaug.Nyob rau hauv ib lub voj voog, qhov no txhais tau hais tias qhov reactance dhau los ua xoom thiab tsuas yog qhov tsis kam.Nyob rau hauv parallel Circuit Court, xoom xaus nyob rau hauv lub denominator ntawm cov feem, yog li ntawd qhov zoo reactance yog infinite (thiab thaum ib tug ntshiab resistor txuas nyob rau hauv parallel, nws tsis hloov tus nqi ntawm tus resistor).Nyob rau hauv ob qho tib si, lub reactance tshem tawm, tawm hauv ib tug ntshiab tsis kam.
Lub ntsiab lus ntawm reactances tshem tawm ib leeg tawm yog hu ua resonance.Lub inclinometer ua haujlwm vim hais tias ntawm qhov taw tes resonance, lub ntsuas hluav taws xob oscillator yuav pom qhov siab tshaj plaws (qis impedance), yog li qhov voltage yuav poob (los yog poob).Ntawm lwm qhov zaus, qee qhov reactance yuav nyob twj ywm thiab tag nrho impedance ntawm Circuit Court nyob rau hauv kev sim yuav siab dua ntawm resonance.
Obviously, lub luag haujlwm tseem ceeb ntawm lub inclinometer yog ntsuas lub resonant zaus ntawm Circuit Court.Yog tias qhov ntawd yog txhua yam nws siv, nws yuav pab tau heev.Tab sis nrog kev siv zog me ntsis, lub inclinometer tuaj yeem ua tau ntau dua.
Ua ntej, nws tseem tuaj yeem ntsuas lwm cov kab hluav taws xob tuned, tsis yog cov khoom siv capacitors thiab inductors.Piv txwv li, cov kav hlau txais xov, muaju, thiab cov kab sib kis yuav muaj qhov tshwj xeeb resonance point, thiab ib lub meter tuaj yeem ntsuas lawv.Rau cov muaju, qhov zaus yog qhov zaus oscillation ntawm cov siv lead ua (nrog qee qhov yuam kev nyob ntawm qhov load capacitance thiab lwm yam).Kav hlau txais xov tuaj yeem ua suab nrov ntawm ntau zaus, tsis yog qhov koj nyiam, yog li yuav tsum muaj qee qhov kev txiav txim siab.Txhua yam uas tsis muaj lub kauj (xws li lub kav hlau txais xov lossis siv lead ua) xav tau lub kauj me me los hloov lub zog ntawm lub ntsuas mus rau lub voj voog.
Rau cov kab hluav taws xob, koj tuaj yeem ntsuas qhov no los ntawm kev ua lub voj me me los txuas lub inclinometer (qhov me dua qhov zoo dua).Nrhiav qhov poob qis tshaj plaws thiab nws yuav qhia 1/4 wavelength ntawm kis kab mob zaus.Piv txwv li, yog hais tias ib tug cable resonates ntawm 7.5 MHz (40 meters wavelength), lub cable yog hais txog 10 meters ntev.Txawm li cas los xij, tsis txhob hnov ​​​​qab xav txog kev sib kis kab ceev.Ntawd yog, ib lub hlis twg-yoj kab sib kis nrog tus nqi ntawm 0.66 yuav luv dua li qhov ntev ntawm txoj kev xav (qhov no, nws tsuas yog 66% ntawm qhov ntev theoretical).
Tau kawg, koj tuaj yeem siv cov kab sib kis tus kab mob li cas koj nyiam.Ntawd yog, koj tuaj yeem tau txais qhov resonant zaus los ntsuas lub cable, lossis koj tuaj yeem teeb tsa qhov zaus thiab kho cov kab rau txoj kab nqes.Qhov tseeb, siv qhov koj paub kom tau txais yam koj tsis paub feem ntau yog lub hauv paus ntsiab lus zoo rau daim phiaj inclinometers.Xav ntsuas lub capacitor tsis paub?Ua kom nws resonant nrog tus paub inductor.Los yog pib nrog lub capacitor paub thiab nrhiav tus nqi rau lub kauj tsis paub.
Txawm li cas los xij, ib qho ntawm cov teeb meem tseem ceeb yog kev nyeem ntawv ntau zaus.Qee qhov niaj hnub sensors muaj cov duab digital (xws li DipIt qhia ntawm sab xis).Txawm li cas los xij, feem ntau cov ntsuas ntsuas siab tsis ua.Ntawm qhov tod tes, koj tuaj yeem yooj yim txuas lawv mus rau lub ntsuas ntsuas zaus lossis siv lub receiver los txiav txim siab qhov zaus.
Muaj kev ntsuas ntau dua yog tias koj tsis mloog qee qhov kev kwv yees.Cov coils muaj Q (Q yam) uas qhia tias lawv muaj kev tiv thaiv ntau npaum li cas rau lawv cov reactance.Siv ib tug zoo siv capacitor, tsim ib tug resonant Circuit Court thiab tig lub ntsuas.Ua tib zoo mloog rau zaus.Tom qab ntawd tig lub inclinometer kom txog thaum koj pom tias nws qhov kev nyeem ntawv ntau npaum li cas yog li 30% siab dua thaum qaij.Tam sim no tsa lub qaij sensor thiab nqes nqes dua kom txog rau thaum koj pom 30% cim dua nyob rau sab nraud.Q yog kwv yees li qhov sib npaug ntawm qhov qis dua muab faib los ntawm qhov sib txawv ntawm ob 30% zaus.
Qhov no yuav pom tseeb, tab sis Ursa Major kuj tseem siv tau yooj yim los ua lub teeb liab.Piv txwv li, txhawm rau kho lub xov tooj cua, koj yuav tsum teeb tsa lub inclinometer rau qhov zaus koj xav kom lub xov tooj cua hnov ​​​​thiab taug qab nws hauv Circuit Court.Ntau lub inclinometers kuj muaj ib hom uas lawv tua lub oscillator thiab siv lub kauj (thiab tuning capacitor) thiab diode raws li lub wavelength meter.Lub 'meter' tom qab ntawd qhia txog qib RF lub zog ntawm qhov zaus tuned.Qee lub sensors txawm muaj lub mloog pob ntseg kom koj tuaj yeem mloog lub teeb liab (ua rau nws yuav luag zoo li lub xov tooj cua siv lead ua).
Ib qho ntawm cov laj thawj ntau tus neeg tsis muaj inclinometers niaj hnub no yog tias lawv tsis tau yooj yim muaj raws li lawv tau ua.Heathkit yog tus neeg muag khoom nrov heev ntawm inclinometers ntawm ntau yam qauv.Lwm cov qauv vintage nrov (feem ntau pom hauv eBay) yog Eico, Millen, Boonton, thiab Measurements Corporation (ceev faj, yog tias koj tsis yog tus sau, cov qauv raj yuav tsis muaj txiaj ntsig zoo).Koj tuaj yeem nrhiav tau cov npe ntawm ntau cov duab GDO ntawm [n4xy] qhov chaw (cov duab yog ob peb nias deb ntawm lub pob tom ntej ntawm nplooj ntawv tseem ceeb).Ntawm sab laug yog daim duab ntawm kuv qhov qub GDO Kev Ntsuas (thiab yog, nws siv cov raj).
Koj tseem tuaj yeem pom cov inclinometers tshiab los ntawm MFJ (lawv muag MFJ-201 qhia ntawm sab xis thiab koj tuaj yeem hloov qee qhov ntawm lawv cov kav hlau txais xov ntsuas rau hauv inclinometers siv tau).Tseem muaj ntau yam kev pab cuam hauv Internet.Yog tias koj xav tau lub raj tiag tiag mod (tsis pom zoo), [w4cwg] muaj cov phiaj xwm.[SMOVPO] qhia txog kev tsim FET niaj hnub nrog lub jumper tshiab los pab ua kom qhov poob qis dua.
Ntawm qhov tod tes, nws zoo li txaj muag los tsim lub tsev tshiab yam tsis muaj cov duab digital.Tau kawg, koj tuaj yeem ntxiv ib qho, lossis siv lub built-in zoo li DipIt lossis ELM.Muaj ntau lwm yam khoom thiab txawm tias cov khoom siv.Saib ib ncig.Qhov nyuaj tshaj plaws yog feem ntau winding lub coils, txawm tias qee qhov yuav xav tau cov capacitors sib txawv uas nyuaj nrhiav.Txawm li cas los xij, hauv kev xyaum, ib qho oscillator uas tuaj yeem ruaj khov yuav ua tau.Qhov tseeb, kuv muaj ob lub thoob Heathkit qub uas siv qhov tsis zoo ntawm qhov diodes li oscillators (ib qho ntawm cov duab ntawm sab laug).
Yog tias koj xav tau cov yeeb yaj kiab ua qauv qhia ntawm kev siv inclinometer, kuv ua tsis tau zoo dua [w2aew], yog li koj tuaj yeem pom nws cov yeeb yaj kiab hauv qab no.

Nov yog ib daim vis dis aus nrog cov ntaub ntawv zoo, Kuv xav tias kuv tau pom nws ua ntej, tsuas yog tshwm sim rau stumble hla duplexers / kab noj hniav lim los ntawm YT AI thiab kuv zoo li… tuaj nrog qhov ntsuas lub kaum ntse ntse no:
gosh kuv tsis yog ib tug hacker kiag li.Kuv tsis nco qab puas tau hnov ​​​​txog lub inclinometer (Kuv tau ua kuv qhov project electronics thawj zaug tshaj 50 xyoo dhau los - nws yog ib tug quartz receiver - tsis muaj roj teeb, tsuas yog ib tug ntev hlau nplaum tawm ntawm kuv lub qhov rais chav pw tig cua) Yog vim li cas kuv kuv Kuv nyeem Hackaday, rau kev kawm tshiab… hmoov zoo kuv tsis tas yuav siv nws.Tej yam zoo li ua haujlwm nrog ESP8266 IOT ua rau kuv tsis khoom thiab tsis tawg mus rau thaj chaw tshiab.Txawm li cas los xij, ua tsaug rau cov lus nthuav dav heev.
Zoo, kuv muaj ob peb, tab sis yog tias koj nyuam qhuav pib tawm thiab xav tau lub cuab yeej uas ua haujlwm tau zoo, tej zaum koj yuav tsis xav nrog cov teeb thiab cov khoom loj loj thaum muaj cov khoom zoo hauv lub xeev.Tam sim no, yog tias koj tab tom sau, nws txawv.
Cov raj hnav dhau lub sijhawm thiab, rau kuv txoj kev paub, coj tus cwj pwm tsis zoo thaum lawv siv cov xaim filament thiab tsim cov deposits.Ua ke nrog rau qhov muaj lawv ntawm cov cuab yeej qub thiab qhov tshwm sim yuav tsis yog qhov koj xav tau.
Koj txoj kev xav txog lub raj yog qhov tsis ncaj ncees lawm: "cov xaim xaim" (yog hu ua filament) tsis cuam tshuam los ntawm kev tso nyiaj.Qhov no yog ib qho kev xav tsis zoo, koj tab tom tsis meej pem cov ntsiab lus lawm, lub raj xa hluav taws xob raug kev txom nyem los ntawm cathodic stripping ntawm high voltage, tsis xa cov cua sov tam sim no hauv thawj qhov chaw.Qhov no tsis cuam tshuam rau lub raj txais.Qhov thib ob, yog tias koj siv lub 'meter', kuv zoo siab tos txais koj, lub teeb tuaj yeem kav ntev dua 5000 teev.Kuv muaj cov cuab yeej sim los ntawm 50s, cov tsev kawm qib siab thiab cov chaw sim nrog cov teeb pom kev qub.Tom qab tag nrho, tsis muaj downsides rau raj inclinometers, ib txhia sib cav hais tias lub tshuab nqus tsev raj ua tau zoo dua ntawm kev kuaj lub raj qaij dua li cov haiv neeg tsawg los yog qhov diodes vim lub raj cutoff yam ntxwv.Kuv xav kom koj mus rau lub raj pheej yig nrog lub ntsuas ntsuas analog, thiab yog tias koj txiav txim siab koj xav tau lub tswb thiab xuav nrog cov duab digital, mus rau nws.
Kuv muaj qhov ntsuas 59 inclinometer uas kuv nyuam qhuav rov qab los zoo li tus mob tshiab.Kuv tau nruab ib lub SMA connector rau ntawm ib sab ntawm lub oscillator rooj plaub thiab ib tug "sniffer" nyob rau hauv ib sab ntawm lub 955 oscillator teeb.Kuv StarTek cov 'meter' kom raug qhia qhov zaus ntawm kuv tus kav hlau txais xov ntxiab lossis lwm yam inductor thaum poob;nws thawj analog scale yog tseem amazingly tseeb.Tsis zoo rau 70s ntsuas uas yooj yim heev thiab siv tau zoo…
Lub teeb ua rau GDOs yooj yim thiab kuv tsis tau muaj teeb meem nrog cov khoom siv hluav taws xob sab nraud.Yog tias ib tug neeg tuaj yeem khawb tau Nuvistor, nws yuav ua ib pob me me.
Qee qhov teeb meem nrog lub xeev "GDOs" yog tias cov transistors bipolar tsis yog qhov sib npaug ntawm cov raj, thiab cov transistors thaum ntxov yeej tsis muaj qhov nce thiab ntau dua cov lus teb.Kuv tsis paub tias Heathkit Tunnel Bucket ua haujlwm zoo npaum li cas, tab sis nws yog lwm yam khoom siv.Yog li ntau lub koob yees duab tom qab siv lwm txoj hauv kev kom pom qhov poob.FETs tshwm zoo li cov raj tsis muaj hluav taws xob, lub rooj vag poob zoo li daim phiaj, MOSFETs tshwm sim, nws yuav tsum poob ib yam nkaus, tab sis koj tuaj yeem pom ntau lub RF ntes kom pom qhov poob.Thaum xyoo 1971, cov txiv neej ntawm Millen tau piav qhia txog kev siv MOSFETs los hloov lawv lub npe GO mus rau hauv lub xeev cov khoom muaj txiaj ntsig.Tib chassis, coils thiab trimmer capacitors.Tag nrho tam sim ntawd, lub "yooj yim" tube Circuit Court yuav tsum tau ua haujlwm ntau, suav nrog ntau lub RF chokes, kom nws teeb tsa yam tsis muaj qhov yuam kev.
Kuv yeej tsis tau tsim, tab sis cov raj zoo li yooj yim thiab cov muag khoom yog complex.
Kuv xav tias GDO ploj mus vim lwm yam khoom siv kuaj.Tab sis tus nqi kuj nce mus.Heathkit los yog Eico pheej yig thiab cov uas nyob ze tshaj yog nyob rau hauv ib puas duas los yog ntau dua qeb.
Tej zaum nyob rau hauv lub voj voog hobbyist, tab sis cov raj tseem siv hnyav heev hauv TV / UHF thiab microwave / satellite daim ntawv thov… #NotAllTubes

Hauv kuv qhov kev paub, lub tshuab nqus tsev diav yog * zoo dua * dua li cov diav.Kuv Eico zoo, zoo li Millen Dipper.Ntaus transistor ladles tsuas yog nruab nrab, lawv qhov ladles tsis zoo.Yog li tsuav koj pom ib qho uas ua haujlwm (lossis ib qho koj tuaj yeem kho tau), hnub nyoog yuav tsum tsis yog qhov tseem ceeb.
Ib tug zoo ladle yuav "xav" lub resonant Circuit Court los ntawm ob peb nti deb ... nws tsis tas yuav txuas ncaj qha mus rau lub kauj raws li qhia nyob rau hauv video.Tsis tas li ntawd, lub 'meter' yuav tsum ruaj khov thaum koj qhib los ntawm ib qho kawg ntawm qhov ntau mus rau lwm qhov.Cov neeg pluag zoo li muaj ntau qhov tsis zoo.
Tus Loj Dipper pab qhia qhov twg yog * tiag tiag * mus rau hauv cov saw hlau.Txhua lub capacitor muaj ib qho inductance thiab txhua tus inductor muaj lub capacitance.Qhov no txhais tau hais tias lawv ib txwm vibrate ntawm ib tug tej zaus.Tsis tas li ntawd, koj lub bypass capacitor dhau los ua ib qho inductor, yog li nws yog qhov phem tshaj qhov tsis muaj txiaj ntsig!Lub Big Dipper kuj tseem tuaj yeem qhia tau tias koj lub voj voog muaj spurious oscillations ntawm qhov kev npaj txhij txog ntau zaus, lossis tias nws txawv txav rau RF ntawm qee zaus.
