Radio-frequency (RF) signal test connection structure and radio-frequency signal test optimization method

Abstract

The invention relates to a radio-frequency (RF) signal test connection structure, which comprises a radio-frequency tester, a tested product is provided with a radio-frequency signal test point, the radio-frequency tester is connected with a probe-type radio-frequency head by a radio-frequency cable, and a probe at the end part of the probe-type radio-frequency head is contacted and connected with the radio-frequency signal test point. The invention also relates to a method for realizing radio-frequency signal test optimization based on the radio-frequency signal test connection structure. The radio-frequency signal test connection structure and the radio-frequency signal test optimization method of the invention have the advantages that: the size of the test point is matched with the used probe-type radio-frequency head; the hardware test connection mode is as follows: an RF output port of the tester, the radio-frequency cable, the probe type radio-frequency head, and the radio-frequency signal test point of the tested product are sequentially connected, therefore, the cost for an antenna connector in a BOM of the tested product is saved; the probe-type radio-frequency head is not easy to be damaged, thereby reducing the test cost; the probe-type radio-frequency head is fixed on a clamp for testing, thereby improving the first pass yield of the tested product; meanwhile, the radio-frequency signal test connection structure and the radio-frequency signal test optimization method of the invention are high in test efficiency, simple in structure, fast and convenient to operate, stable and reliable in operating performance, and wide in application scope.

Description

technical field [0001] The invention relates to the field of radio frequency communication, in particular to the technical field of radio frequency signal testing, and specifically refers to a radio frequency signal test connection structure and a radio frequency signal test optimization method. Background technique [0002] Nowadays, radio frequency technology is widely used in various fields, such as: TV, radio, mobile phone, radar, automatic identification system, etc. Products designed with radio frequency functions must undergo a series of radio frequency index tests before delivery to meet product requirements. requirements. [0003] At present, most manufacturers in the industry use conduction testing in the mass production and testing of products, that is, the hardware connection method is: test instrument radio frequency (RF) port + RF cable + RF connector + product antenna connector. Then use software to control the instrument on the PC side for automated testing....
