Function generators yog hom pib tshaj plaws ntawm cov teeb liab generator. Lawv tsim ntau yam waveforms, xws li sine waves, square waves, thiab triangular waves. Lawv feem ntau siv rau cov hom phiaj kev kawm hauv electronics labs.

Arbitrary waveform generators yog complex tshaj li muaj nuj nqi generators. Lawv muaj peev xwm ua tau ntau dua waveforms, nrog rau cov arbitrary waveforms thiab digital signals. Lawv feem ntau yog siv rau kev sim thiab ntsuas hluav taws xob thiab kev sib txuas lus.

RF signal generators yog siv los tsim cov teeb liab hauv xov tooj cua ntau zaus. Lawv tau siv rau hauv kev tsim thiab kev sim ntawm RF systems, xws li xov tooj cua thiab satellite kev sib txuas lus.

Daim ntawv thov ntawm Signal Generators

Cov teeb liab hluav taws xob tau siv ntau yam kev siv, suav nrog:

1. Kev ntsuas thiab ntsuas hluav taws xob thiab kev sib txuas lus
2. Calibrating cov khoom siv hluav taws xob
3. Tsim thiab tsim kev sib txuas lus, xws li xov tooj cua thiab satellite kev sib txuas lus
4. Kev tshawb fawb thiab kev loj hlob hauv kev lag luam hluav taws xob

Teeb liab Generator Specifications

Cov teeb liab hluav taws xob muaj cov yam ntxwv los ntawm ntau qhov tshwj xeeb, suav nrog ntau zaus, lub zog tso zis, thiab impedance.

Ntau zaus yog hais txog qhov ntau zaus uas lub teeb liab generator tuaj yeem tsim. Qhov ntau zaus ntawm lub teeb liab generator nyob ntawm hom generator. Function generators feem ntau muaj ntau zaus txog li ob peb puas kilohertz. Arbitrary waveform generators muaj ntau zaus ntawm ntau megahertz. RF teeb liab generators muaj ntau zaus ntawm ntau gigahertz.

Lub zog tso zis yog hais txog lub zog ntawm lub teeb liab tsim los ntawm lub teeb liab generator. Nws yog ntsuas hauv volts lossis decibels (dB).

Impedance yog hais txog qhov tsis kam ntawm lub teeb liab generator tso zis. Nws feem ntau yog ntsuas hauv ohms.

Teeb liab Generator nta

Cov cim hluav taws xob feem ntau muaj ntau yam nta, suav nrog kev hloov kho, cheb, thiab tsim suab nrov.

Modulation yog tus txheej txheem ntawm kev sib txawv ntawm lub teeb liab qhov amplitude, zaus, lossis theem. Modulation feem ntau yog siv rau hauv kev sib txuas lus los xa cov ntaub ntawv hla lub teeb liab ntawm tus neeg nqa khoom.

Sweep yog tus txheej txheem ntawm kev sib txawv qhov zaus ntawm lub teeb liab lub sijhawm. Qhov no feem ntau yog siv rau hauv calibration thiab xeem daim ntawv thov.

Lub suab nrov yog cov txheej txheem ntawm kev ntxiv suab nrov rau lub teeb liab. Qhov no feem ntau siv rau hauv kev sim thiab ntsuas hluav taws xob thiab kev sib txuas lus.
