Tus ntsuas lub network yog cov ntsuas uas ntsuas cov ntsuas hluav taws xob ntawm lub network hluav taws xob. Niaj hnub no, cov kws soj ntsuam kev sib koom tes feem ntau ntsuas s – tsis tau vim tias kev xav thiab kev sib txuas ntawm cov xaim hluav taws xob tau ntsuas tau yooj yim ntawm qhov ntsuas siab, tab sis muaj lwm lub network parameter teeb tsa xws li y-tsis, z-tsis, thiab h-tsis tau. Network analyzers feem ntau siv los cim ob-chaw nres nkoj sib txuas xws li cov amplifiers thiab cov ntxaij lim dej, tab sis lawv tuaj yeem siv rau hauv kev sib txuas nrog cov zauv tsis txaus ntawm cov chaw nres nkoj.
Network analyzers siv feem ntau nyob ntawm qhov muaj ntau zaus; kev khiav hauj lwm ntau zaus muaj txog ntawm 5 Hz txog {{1}}. 05 THz. [1] Cov kev sib txuas ntawm cov network tshwj xeeb kuj tseem tuaj yeem txo qhov qis tsawg dua rau { {{1}} Hz. Cov kws ntsuas hluav taws xob hauv network no tuaj yeem siv ua piv txwv rau kev ntsuas kev ruaj ntseg ntawm qhib lub voj lossis rau kev ntsuas ntawm lub suab thiab ultrasonic Cheebtsam.
Qhov ob theem pib hom ntawm lub network analyzers yog
● scalar network analyzer (SNA) - cov khoom loj ntau yam tsuas yog
Zer vector network analyzer (VNA) - ob qho tib si cuam tshuam thiab theem yam ntxwv
A VNA yog ib hom ntawv ntawm RF network analyzer dav siv rau RF tsim kev siv. VNA kuj tseem yuav raug hu ua tus nce-theem 'meter' lossis tus ntsuas lub network tsis siv neeg. Tus SNA tau ua haujlwm zoo ib yam li ib qhov tsom xam spectrum hauv kev sib txuas nrog lub tshuab hluav taws xob nrhiav. Raws li ntawm 2007, VNAs yog hom kev sib txuas ntawm cov network analyzers, thiab yog li xa mus rau" tsis tsim nyog; network analyzer" feem ntau cov txhais tau tias yog VNA. Peb qhov ua lag luam rau VNA tseem ceeb yog Keysight, Anritsu, thiab Rohde& Schwarz.
Lwm hom kev ntsuas lub network yog microwave txoj kev hloov mus tshuaj ntsuam xyuas (MTA) lossis lub teeb liab loj network analyzer (LSNA), uas ntsuas ob qhov loj thiab theem ntawm qhov tseem ceeb thiab kev sib raug zoo. MTA tau ua lag luam ua ntej LSNA, tab sis tau muaj qee qhov ntawm cov neeg siv qhov kev ntsuas zoo tam sim no muaj nyob nrog LSNA.
