Development of a new line impedance stabilization network system

There are many common products of linear impedance stability network (LISN) presently, each with its own advantages and disadvantages. This paper presented a new line impedance stabilization network (LISN) system, which improved the past LISN system under the premise of perfecting various additional features, making it more convenient. The cost is relatively low. Finally, to consistent with the designed measurement system, it make use of the Labview language to prepare the automatic measurement software for test system real-time monitoring and configuration, test parameters setting, test data collection, display, processing and storage. It also considered the impact of the environmental parameters and testing equipment to the test results. The reasonableness and practicability of the system have been confirmed by test.
