Abstract

The invention discloses a test system for an interface board. The test system for the interface board comprises a vector network analysis unit and a signal transfer unit, wherein the signal transfer unit is used for inputting first original signals of a to-be-input interface board respectively to the vector network analysis unit and an interface board, for receiving second transmitting signals output by the interface bard after second original signals are transmitted by the interface board, and for transmitting the second transmitting signals to the vector network analysis unit; and the vector network analysis unit I is used for receiving the first original signals, for receiving first transmitting signals output by the interface bard after the first original signals are transmitted by the interface board, for testing the interface board according to the first original signals and the first transmitting signals, for receiving the second original signals of the to-be-input interface board, for accessing the second transmitting signals from the signal transfer unit, and testing the interface board according to the second original signals and the second transmitting signals. By means of the technical scheme, the problem that an existing test method is not perfect is resolved.

Description

technical field [0001] The invention relates to the communication field, in particular to an interface board testing system. Background technique [0002] The digital microwave transceiver (Out Door Unit, ODU) is the outdoor equipment unit in the entire microwave relay communication system, and its working frequency is currently divided into 6G, 7G, 8G, 11G, 13G, 15G, 18G, 23G, 32G according to the frequency band , 38G, 42G and other 11 frequency bands, the specific frequency bands are determined according to the open resources of each country. Its transmission power is usually within 1W, and the longest communication distance is about 80km (related to the working frequency band and power generation capability). [0003] ODU is one of the performance bottlenecks in the whole microwave relay communication. Because of its high operating frequency, high requirements on device technology and strict requirements on reliability, the price of ODU is very high. Moreover, in the m...
