Kodi angathe kuyeza ndi chowunikira sipekitiramu

Kodi sipekitiramu chowunikira? Ndi mankhwala inu simudzakhala nawo pamoyo wathu wa tsiku ndi tsiku, ndi ndithu chipangizo yeniyeni, ndipo ndi okwera mtengo kwambiri. M'nkhaniyi, tiona zofunikira komanso kugwiritsa ntchito zipangizo zimenezi. Mwachidule, ndi sipekitiramu chowunikira ndi chipangizo kuti akhoza kukhala pafupipafupi kusankha voltmeter, omwe sagwirizana matalikidwe anafotokoza, ndi kukhazikitsidwa kuti kusonyeza rms mtengo wa yoweyula sine. Ndipo izo ziri basi mu Mwachidule, kwenikweni zambiri zovuta ndi chidwi.

Nkofunika kuzindikira kuti chida ichi si mphamvu mita, ngakhale kuti sipekitiramu chowunikira akhoza mwachindunji kusonyeza mtengo wa chizindikiro ichi. Ngati tizindikira kufunika pafupifupi kapena nsonga ya yoweyula sine ndi mtengo kukana, n'zotheka sintha chipangizo kusonyeza makhalidwe linanena bungwe. Chifukwa cha chitukuko cha luso digito masiku ano sipekitiramu analyzers ndi mwayi moona lonse.

Kumvetsa cholinga cha chida ichi, m'pofunika kuganizira zimene anayeza ndi chowunikira sipekitiramu. mungadziwire dzina la chipangizo kuti ntchito kuyeza sipekitiramu. Ndipo kodi makhalidwe? The sipekitiramu ndi ya mafunde sinusoidal, imene pa osakanizidwa ena angathe kupereka chizindikiro malipoti ndi yachigawo nthawi ankalamulira. Choncho, mbendera ali mawonekedwe umodzi chakale sinewave. Zochita mu pafupipafupi ankalamulira ndi chowunikira sipekitiramu Tingaone kuti sipekitiramu cha chizindikiro ndizo mafunde ziwiri kapena zambiri, mwina muli amgwirizano chachiwiri ndi ena. Mu nthawi ankalamulira mosavuta anayeza nthawi zimachitika m'mphepete ndi m'mphepete ake akugwa, komanso mpweya ndi chizindikiro runout . chizindikiro sipekitiramu chowunikira miyezo mu ankalamulira pafupipafupi n'kofunika pamene kupanga ziwembu kulankhulana opanda zingwe. Only ndi thandizo pogwiritsa n'zotheka kudziwa otsekula kuthetsa-gululo ndi mpweya konyenga. Monga tanenera, chipangizo limalola kupeza amgwirizano chizindikiro, ndipo chizindikiro mu zida wailesi kupatsira n'kofunika kwambiri, chifukwa harmonics zina akhoza kugwa pa pafupipafupi ntchito ndipo potero kudzetsa kusokonezedwa.

Komanso, chipangizo izi amachita ngati zomvetsera chowunikira sipekitiramu. Kodi zikutanthauza chiyani? Nthawi zina m'pofunika kuchita miyezo phokoso ngati chizindikiro wamba. chipangizo china chilichonse kapena dera yogwira kwaiye phokoso. Chotero phokoso chiŵerengero muyeso ndi chiŵerengero chizindikiro / phokoso ndi makhalidwe ofunika wamba chizindikiro chipangizo ndi dongosolo.

Polongosola mwachidule, tinganene kuti pakompyuta zida kuyesa yesa ndi zipangizo cholinga akusowa sipekitiramu chowunikira. Mtengo pogwiritsa N'zochititsa chidwi kwambiri ndi zimasiyanasiyana pa osiyanasiyana. Mwachitsanzo, mmodzi wa zipangizo losavuta (Rigol DSA815) ndalama za 50-60 zikwi rubles, koma kulipira 750-800 zikwi rubles kwa akatswiri sipekitiramu chowunikira (Agilent matekinoloje). Radio ankachita masewera kuti msonkhano wake kunyumba ndi chodziwikiratu kuti kugula chipangizo oterowo, koma makampani kapena Laboratories makampani chinkhoswe mu chitukuko cha luso zamagetsi, ndi lofunika.
