Vim li cas cov neeg siv hluav taws xob vector networkzer (VNA) kev sim cov cable feem ntau kim

 

Tus nqi ntawm Vector Network Analyer (VNA)

{{0 {}} Tsis xav tau cov ntawv yuav tsum tau ua

Kev xeem ntaublna xeem khiav haujlwm hauv MHz txog ntau pua qhov kev ntsuas ntawm kev ntsuas ntawm kev ntsuas, thiab yuav tsum tau poob qis dua, thiab theem ruaj khov.

Kev ua tau zoo tseem ceeb yuav tsum muaj:

Tsawg txoj kev poob siab: Hauv cov hlua hluav taws xob he-.}}}}}}}}}}}}}}} .

High rov qab poob (impedance txuam): VNA kev ntsuas yog qhov rhiab heev rau cov paib kev sib txawv (feem ntau yog qhov tsis muaj peev xwm ua kom muaj qhov tseeb thiab cov kev ua tsis tau zoo li qub (feem ntau) yog li 50% nti).

Theem Ruaj Khwv: Theem kev hloov tshwm sim los ntawm cable txav (xws li khoov) lossis qhov kev hloov kho kub (xws li theem, yog li kev ua haujlwm tshwj xeeb .

Electromagnetic cuam tshuam (EMI) / Xov tooj cua Kev cuam tshuam hluav taws xob sib cuam tshuam (RFI): Txhawm rau tiv thaiv kev cuam tshuam sab nraud sab nraud thiab cov phiaj xwm zoo li no ua rau cov khoom siv polymer), uas cov nqi zog polymer), uas nce cov nqi zog thiab cov nqi zog.

 

2.} Cov ntaub ntawv tshwj xeeb

Cov ntaub ntawv siv nyob rau hauv VN tshib yog ua tib zoo xaiv kom tau raws li kev ua tau zoo thiab kev ruaj khov yuav tsum muaj:

Tus saib xyuas: High-purity oxygen-dawb tooj lossis nyiaj-plated / kub} Kuv muaj feem ntau tab sis siv rau cov txuas thiab sab hauv.

Dosau: Tsis muaj kev poob qis, muaj kev ruaj khov kho xws li nthuav dav PTFEsab tsis tu ncua nrog kev hloov pauv thiab zaus, tab sis lawv yog qhov nyuaj rau cov txheej txheem .

Sheathing: Siv tau cov ntaub ntawv tsis yooj yim (xws li fluoropolymers, polyurethane ({}} Cov ntaub ntawv yog ntau dua kim dua li dog dig dog dig dog dig dog dig dog dig dog dig dog dig dog dig dog dig dog dig dog dig dog dig dog dig dog dig dog dig dog dig decog pvc {}}

 

3. precision kev lag luam thiab cov txheej txheem tsim

Tus qauv tsim thiab kev tsim tawm ntawm VNA cable yuav tsum tau muaj micrometer-qib precision:

Qhov seem ntev: Cov geometries ntawm cov tuav hauv sab hauv, thiab sab nraud ntawm kev ua kom tsis txhob muaj kev cuam tshuam los ntawm eccentricity) yuav tsum tau tswj hwm hauv micrometer ntau .

Cov txheej txheem nyuaj: Ntau ntau zaus ntxiv cov txheej txheem ua haujlwm tau txais txiaj ntsig, xws li theem kev ruaj khov thiab qis dua PTFE los txo qhov hnyav thiab poob .

Kev Kho Mob High-Precision Kev Sib Tham: Cov khoom siv tseem ceeb ntawm ultra-high-zaus clescles (xws li cov sib txuas) tej zaum yuav xav tau kev sib dhos thiab kev nce qib, uas nce kev ua haujlwm raug nqi.

 

4. high-kev ua tau zoo sib txuas

Connectors yog qhov tseem ceeb ntawm VNA cable cables, thiab ua yeeb yam tsis zoo ua tau yog qhov chaw ntsuas tsis raug . Lawv yuav tsum:

Precision Machining: Connectors (xws li SMA, 3 {{}}}}}}

Plating kho: Kub lossis rho tawm plating (5-50 microinches tuab), corrosion tsis tshua muaj kev tiv thaiv, thiab kev ua tiav zoo rau kev ntsuas).

Kev kuaj thiab ntawv pov thawj: Txhua lub txuas txuas yuav tsum tau kuaj seb cov hluav taws xob voltage (VWSWR), ntau lub sij hawm poob siab / extractive kauj ruam .

 

5. ib puag ncig kev ruaj khov

Kev cog qoob loo VNes yuav tsum muaj kev tiv thaiv hnyav hauv kev kuaj, chaw ua haujlwm, lossis kev sim ua si:

Yooj taus thiab ruaj khov: Lawv yuav tsum tiv thaiv nws txoj kev khoov, sib npaug yam tsis muaj kev nyuaj siab nyob rau hauv kev ua tau zoo {} Qhov no yuav tsum tau txhim kho sab hauv txhawb nqa kev txhawb nqa thiab ruaj khov.

Thiab huab cua tsis kam: Cov ntaub ntawv yuav tsum nyob ruaj khov nyob rau hauv qhov dav dav, thiab nthuav tawm cov tshuaj thiab cov kuab tshuaj (kim engineering plastics thiab elastomers siv
