Abstract
The utility model relates to a network cable quick test instrument, which comprises a transmitting circuit and a receiving circuit. The transmitting circuit comprises a high-frequency transmitting circuit, a control circuit, and a drive circuit. The transmitting circuit generates a high-frequency pulse which generates an intermediate frequency scanning signal by a control circuit. The drive circuit receives the pulse signal emitted by the control circuit at any moment. And then, the make and break can be intuitively judged for an instant for the 9 lines in the twisted pair of a group of network cables. The utility model is applicable for volume testing the cable twisted pair, simple to be operated, strong in reliability and also suitable for the operation in the open.
