The invention provides a test frame, a shielding effectiveness test system and a test method thereof. The test frame comprises a grounding flat plate, a first supporting plate, a second supporting plate, a shielding tube, a receiving antenna and a transmitting antenna, wherein the first supporting plate is fixedly connected on the grounding flat plate, the second supporting plate is fixedly connected on the grounding flat plate, one end of the transmitting antenna is connected on a first coaxial connector, the other end of the transmitting antenna is connected on a third coaxial connector, oneend of the receiving antenna is connected on a second coaxial connector, and the other end of the receiving antenna is connected on a fourth coaxial connector; and one end of the shielding tube is connected on the first supporting plate, the other end of the shielding tube is connected on the second supporting plate, and the receiving antenna is sleeved in the shielding tube. The test frame, theshielding effectiveness test system and the test method thereof can effectively measure or evaluate the shielding effectiveness of shielding tube-like objects, and is simple in operation and precise in measurement result.
Description
technical field [0001] The invention relates to the technical field of electromagnetic shielding, in particular to a test frame, a shielding effectiveness test system and a test method thereof. Background technique [0002] With the rapid development of information technology, more and more information needs to be transmitted through lines, communication lines are becoming more and more dense, crosstalk and information leakage between communication lines are becoming more and more serious, and the problem of line shielding has attracted widespread attention; The shielding tube or soft shielding cloth wrapping method is used to solve the problem of signal leakage or external interference through the technical means of isolation and shielding, so as to improve the shielding effectiveness between communication lines. [0003] In the prior art, there is no suitable measurement method or evaluation method for the shielding effectiveness of soft shielding cloth wrapping or shieldi...
