Cable Loop Fault Analyzer

Introduction: DC-390 telecom cable loop fault analyzer is developed according to customer’s application requirement. It combines the functions of multi-meter/bridge test/impulse test and so on, and able to quickly and accurately locate where the problem is and what kind of problem it is, including: disconnection/swinging cross/poor insulation and so on. DC-390 adapts the high speed processor with 200M/S main frequency, newest brighten displayer and unique “skylight” displayer design, which accelerate the test speed and solving the problem of display and water-proof under bright light and cloudy rainy weather. At the same time, it chooses the firm back-taking cabinet,plug and play free integrated testing line, which allow disassemble rechargeable battery and ordinary battery. It is more convenient for using under different situation (for example: on the electric pole), strengthen the user’s working efficiency. Function features DC-390 obtains the function of problem analyzing and locating Impulse test and bridge test join together to success in testing all types of local call cable problems. TDR can accurately locate the cable problems as disconnection/short circuit/water penetration and so on. Bridge test can accurately locate the problem as dichi/insulation and so on. Automatically test and problem analyzing function: press “auto” button to start basic test. The data indicates how far the problem is and what problem is. Has hand testing and automatically test two types, both with accurate result. Obtains the function of multi-meter, can test the insulation resistance and loop resistance. Simple operation, “skylight” working model allows function transfer by switch. Adapt the world first created bipolar impulse emission technique, improving the effective testing length, especially suit for the test of giant wire pair/plastic cable with thin diameter DAGC digital gain auto control system; full-automatic data gain adjust. Blur waveform identification technique; Machine automatically identifies waveform, eliminate test blind zone. Real 32 bits single-chip microcomputer cooperated with fast control circuit technique, device processes all types of complicated calculation, fast and accurately locate how far the problem locates. Advanced 200MHz sampling frequency, with higher resolution ratio. 320×240 dot matrix large screen liquid displayer, show vivid picture, character and data, with CCFL background light, user can get the best display under different light circumstances. DC-390’s unique “skylight” display design, user can test without open the cover of the device, which effective to anti-water and dust, lengthen the using life. Obtain online control function. Connecting with PC, it is convenient to form waveform database and process automatic identification, as well as establish wire test management system according to customer. Super waveform data storage function. It allows save test result more than 500 groups for post analyzing. Expertise analyzing software, able to document, print and analyze waveform on PC. USB interface can connect with U-disk, USB mouse and USB keyboard. Great capacity of rechargeable battery which can be dissembled, protective recharging, endure continuously using of more than 5 hours. Battery can be changed immediately, shorten fixing time, lengthen normal using life. Allows ordinary battery for outdoor and urgent situation Firm back-taking design, unique “skylight” design for rainy day, back-taking design good for working aloft. Withstand impact, water-proof, easy-taking and suit for outdoor. The weight is only 2.0kg, light enough to put on table/ ground or hanging above. Integrated connection wire, avoid the damage or loss of plug and play. Integrated test connection line, avoid
