The invention relates to the field of wireless communication, and discloses a line loss point inspection system and method. The line loss automatic point inspection system comprises a radio frequency test device, a production clamp, a switch module, a power meter and a control terminal; the switch module comprises M test ports, a reference port and an output port; each test port is connected to radio frequency test equipment through a corresponding test radio frequency line; the reference port is connected to radio frequency test equipment through a reference radio frequency line; the output port is connected with a calibration power detection point of the power meter; each test port can be connected with or disconnected from the output port; each test port can be connected with or disconnected from the reference port; and the output port can be connected with or disconnected from the reference port; and the control terminal is used for performing selective conduction control on the switch module according to a target test radio frequency line so as to perform line loss test on the target test radio frequency line. According to the line loss point inspection system and method embodiment of the invention, line loss measurement can be realized by controlling the switch module through software, manual connection operation is not needed, and the line loss measurement precision and the production efficiency are improved.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a system and method for line loss point inspection. Background technique [0002] With the development of electronic information, the manufacturing of electronic products has also become an important node in product development. The test of radio frequency signals is integrated in the shielding box of the production fixture. The signal line realizes the connection between the radio frequency test equipment and the main board of the electronic product to be produced. In order to quickly realize mass production, it is necessary to quickly realize the loss point inspection of the RF connecting line on the fixture, so as to realize the power calibration of the RF test, and quickly and effectively solve the problem of mass production. [0003] The current line loss point inspection schemes mainly include the following three types, each of which has obvious defects: [0004] (1)...
