Abstract
To detect amplitude-frequency characteristics of filter with single or differential port is introduced. A novel instrument to detect amplitude-frequency characteristics of xDSL filter is designed considering the specific detection requirement, which applies with multiple modern technologies of MCU, DDS, LPF, auto control and high-frequency small-signal amplification. The verifying experiment contrasted with traditional detection method shows that the instrument can detect fast and accurately with reduced detection cost and convenience to use the test result.
