A spectrum analyzer ntsuas qhov loj ntawm aninput teeb liab piv rau zaus nyob rau hauv tag nrho ntau zaus ntawm qhov ntsuas. Qhov tseem ceeb siv yog ntsuas lub zog ntawm lub spectrum ntawm cov cim paub thiab tsis paub.
Ib yam li ntawd, nws raug nug, tus spectrum analyzer ua li cas?
A spectrum analyzer yog ib daim ntawm cov khoom siv hluav taws xob uas siv los ntsuas qhov loj (amplitude orstrength) ntawm ib lub teeb liab muab tso tawm rau tag nrho cov zaus ntawm qhov ntsuas. Nws yog feem ntau siv los ntsuas lub zog ntawm lub spectrum ntawm paub thiab tsis paub.
Tsis tas li ntawd, qhov sib txawv ntawm lub teeb liab analyzer thiab spectrum analyzer yog dab tsi? Cov sib txawv sawv hauv ntsuas tau thiab yuav ua li cas lawv ua. Thaum a spectrum analyzer tsom xam ib qho kev siv teeb liab , ib network tus ntsuas tsim ib teeb liab thiab characterizes cov khoom uas tau txais. Cov spectrum analyzer , ntawm qhov tod tes, yog siv tomeasure carrier fais fab theem, suab nrov harmonics, thiab lwm yam.
Ib tug kuj yuav nug, qhov txawv ntawm lub spectrum analyzer thiab oscilloscope yog dab tsi?
Thaum ib oscilloscope qhia ib lub teeb liab nrog rau lub sij hawm, a spectrum analyzer qhia nws nrog hwm zaus . Peb tuaj yeem siv ib qho oscilloscope nrhiav tus txheeb ze ncua sij hawm nruab nrab ob lub teeb liab. Ntawm qhov tod tes, los soj ntsuam cov zaus cov khoom ntawm lub teeb liab, a spectrum analyzer yog yuav tsum tau.
Lub optical spectrum analyzer ua haujlwm li cas?
Lub photodetector ces converts tus kho qhov muag teeb liab mus rau ib qho hluav taws xob tam sim no proportional rau qhov xwm txheej kho qhov muag zog. Qhov dav nthuav dav ntawm txhua hom ntawm lub laser yog kev ua haujlwm ntawm cov spectral daws teeb meem ntawm lub wavelength-tunable kho qhov muag lim. Daim duab 2. Simplified Optical spectrum analyzer thaiv daim duab.
