Abstract

The invention discloses a multifunctional cable tester. The multifunctional cable tester comprises a power supply circuit, an MCU circuit, a low voltage detection driving circuit, a high voltage detection driving circuit, a microwave noise source, a signal acquisition and amplification circuit, a microwave detection circuit and a display circuit. The multifunctional cable tester is divided into three independent function parts and two common function parts in the internal circuit design. The three independent function parts are a direct current resistance measurement part, a direct current insulation resistance measurement part and a coaxial line loss measurement part. The two common parts are a power source and a logic processing part. Basic parameters of a wire and a cable are measured in a single instrument, the test coverage rate is high and the accuracy of the test precision is high, and therefore the overall performance of the cable is ensured more effectively.

Description

technical field [0001] The invention belongs to the field of cable testing, in particular to a multifunctional cable testing instrument. Background technique [0002] Cable is a general term for optical cables, wires and cables, etc. used for optical signal transmission items. Cables have many uses and can be seen everywhere in real life. They are mainly used to control installation, connect equipment, transmit power and signal transmission, etc. They are common and indispensable items in daily life. [0003] Since cables are mainly used for signal transmission, there are certain requirements for their physical characteristics and electrical performance. Various tests need to be carried out during use to check whether its performance is normal and meets the requirements of use. The detection content generally includes open circuit short circuit, wiring error, insulation performance, withstand voltage performance, attenuation and crosstalk, etc. [0004] With the developme...
