Yuav ua li cas yuav ntsuas los ntawm ib tug spectrum analyzer

Yuav ua li cas yog ib tug spectrum analyzer? Nrog cov yam khoom no koj yuav tsis ntsib nyob rau hauv lub neej txhua hnub, nws yog ib tug heev cov kev ntaus ntawv, thiab yog heev kim. Nyob rau hauv no tsab xov xwm, peb yuav xav txog qhov nqi hluav taws xob thiab siv cov kiag li lawm. Nyob rau hauv ib nutshell, lub spectrum analyzer yog ib tug ntaus ntawv uas yuav piav raws li ib tug zaus xim voltmeter, uas reacts mus amplitude, nws yog configured thiaj li mus saib tus rms nqi ntawm cov sine yoj. Thiab hais tias yog cia li nyob rau hauv ib tug nutshell, nws yog ua tau ntau npaum li cas complex thiab nthuav.

Nws yog ib qho tseem ceeb kom nkag siab txog hais tias qhov no lub cuab tam tsis yog lub hwj chim 'meter', txawm lub fact tias lub spectrum analyzer yuav ncaj qha tso saib tus nqi ntawm no parameter. Yog hais tias peb paub qhov nruab nrab los yog ncov nqi ntawm cov sine yoj thiab cov kuj nqi, nws yog ua tau rau configure tus ntaus ntawv mus tso saib cov qhov tso zis qhov tseem ceeb. Tsaug rau txoj kev loj hlob ntawm cov technology, niaj hnub spectrum analyzers muaj ib tug tiag tiag ntau possibilities.

Yuav kom to taub lub ntsiab ntawm qhov ntsuas, nws yog tsim nyog los xav txog dab tsi yog ntsuas nrog ib tug spectrum analyzer. koj yuav qhia tau los ntawm lub npe ntawm tus ntaus ntawv hais tias nws yog siv los ntsuas lub spectrum. Thiab yog dab tsi zoo ntawm cov yam ntxwv? Lub spectrum yog ib tug txheej ntawm sinusoidal tsis, uas nyob rau tej qhov kev sib txuas tau muab ib lub teeb liab qhia txog sectional lub sij hawm sau. Qhov tseeb tiag mas, lub teeb liab muaj hauv daim ntawv ntawm ib tug tib classical sinewave. Nyob rau hauv kev xyaum, nyob rau hauv lub zaus sau nrog ib tug spectrum analyzer yuav pom tias lub spectrum ntawm lub teeb liab muaj ob vuag los yog ntau tshaj, tej zaum nws yuav muaj ib tug thib ob harmonic thiab lwm tus neeg. Nyob rau hauv lub sij hawm sau tau yooj yim ntsuas ntev mem tes ntug thiab nws ntog ntug, raws li zoo raws li emissions thiab teeb liab runout . teeb liab spectrum analyzer ntsuam nyob rau hauv lub zaus sau yog tsim nyog thaum tsim ib wireless kev sib txuas lus schemes. Tsuas yog nrog kev pab los ntawm no ntaus ntawv nws yog ua tau rau ntes thiab tom qab tshem tawm-band thiab spurious emissions. Raws li tau teev saum toj no, tus ntaus ntawv tso cai los mus taw qhia ntxiv harmonic teeb liab, thiab cov parameter nyob rau hauv lub xov tooj cua kis apparatus yog ntawm kuj zoo kawg tseem ceeb, vim hais tias cov ntxiv harmonics tej zaum yuav poob rau cov zaus ua hauj lwm thiab yog li ua rau cuam tshuam.

Tsis tas li ntawd, qhov no ntaus ntawv ua raws li cov suab spectrum analyzer. Ua li cas nws txhais li cas? Tej zaum nws yog tsim nyog los nqa tawm suab nrov ntsuam raws li ib tug dog dig teeb liab. Tej ntaus ntawv los yog active Circuit Court generated suab nrov. Tej suab nrov piv ntsuas thiab teeb liab / suab nrov piv yog ib qho tseem ceeb cov yam ntxwv ntau qhia ntaus ntawv thiab system.

Summing li, peb hais tias hluav taws xob cov khoom siv los mus ntsuam xyuas thiab debug cov tsim cov khoom cia li xav tau ib tug spectrum analyzer. Tus nqi ntawm no ntaus ntawv yog heev tseem ceeb thiab txawv tshaj ib tug ntau yam. Piv txwv li, yog ib lub nyuaj kiag li lawm (Rigol DSA815) yuav raug nqi txog 50-60 txhiab rubles, tab sis yuav tau them 750-800 txhiab rubles rau cov kev spectrum analyzer (Agilent yees). Xov tooj cua amateur rau nws lub tsev rhiav yog tsis zoo li yuav tsum tau yuav xws li ib tug ntaus ntawv, tab sis lub tuam txhab uas muag los yog lub chaw soj nstuam ntawm tuam txhab uas muag koom nyob rau hauv txoj kev loj hlob ntawm hluav taws xob technology, nws yog ib tug yuav tsum.
