BIS Broadband Impedance Cable Fault Locator

BIS Broadband Impedance Cable Fault Locator

Lub MOEORW-WLF10 yog lub portable cable broadband impedance defect locator. Nws ua haujlwm tsis yog -kev ntsuas kev puas tsuaj nrog qhov tseeb ntawm qhov chaw<0.5%, fast testing speed, and long battery life.

Nws yog qhov tsim nyog rau cov kab hluav taws xob hluav taws xob ntawm txhua qhov hluav taws xob, tuaj yeem nrhiav cov teeb meem me me thiab cov teeb meem sib koom ua ke, thiab tsim nyog rau ntev - deb thiab submarine cables.

BIS Kev Taw Qhia

Txoj kev Broadband Impedance Spectrum (BIS) tau tsim los daws qhov tsis txaus ntawm lub sijhawm ib txwm muaj -domain reflection (TDR) hauv kev nrhiav qhov tsis xws luag hauv zos hauv cables. Cov cuab yeej siv tau yooj yim no, nruab nrog lub roj teeb rov qab, yog qhov tsis yog - kev ntsuas kev puas tsuaj. Los ntawm kev sib xyaw ua ke ntawm tus kheej-tsim CBIS kuaj software thiab kho vajtse, lub kaw lus pom muaj kev nkag siab zoo thiab qhov tseeb hauv kev txheeb xyuas qhov tsis xws luag hauv zos thiab nruab nrab cov pob qij txha hauv cov cables, nrog rau qhov chaw yuam kev ntawm<0.6%. Employing frequency domain measurement principles, it detects the reflection of an incident signal (a sinusoidal linear sweep signal with a fixed frequency step) at the impedance discontinuity. By analyzing the reflected wave (or a standing wave composed of the incident and reflected waves) at the transmitting end and calculating the location of the impedance discontinuity based on the cable's propagation speed, the system can effectively address these issues .
