The invention relates to a production test circuit board, a radio frequency parameter calibration system, a radio frequency parameter calibration method and computer equipment. An SMA interface, a program control attenuation chip and a processing chip are integrated on the production test circuit board, wherein the SMA interface is used for being connected with a to-be-tested module and transmitting a radio frequency signal transmitted by the to-be-tested module to the program control attenuation chip; the program control attenuation chip is used for receiving a radio frequency signal transmitted by the to-be-tested module, adjusting an attenuation value according to a difference value between a radio frequency parameter of the radio frequency signal and a radio frequency parameter of a gold plate so as to attenuate the received radio frequency signal, and transmitting the attenuated radio frequency signal to the processing chip through a radio frequency line; and the processing chip is used for receiving the radio frequency signal transmitted by the program control attenuation chip, analyzing whether the radio frequency signal accords with a preset parameter range, and sending an analysis result to an upper computer, so that the upper computer adjusts the radio frequency parameter of the to-be-tested module according to the analysis result until the radio frequency parameter of the to-be-tested module accords with the preset parameter range. An original comprehensive tester is replaced by the production testing circuit board, and the problem that the production testing cost of the networking module is high is solved.
Description
technical field [0001] The present application relates to the technical field of testing, in particular to a production testing circuit board, a radio frequency parameter calibration system, method and computer equipment. Background technique [0002] At present, WiFi products have generally been implanted into electronic devices such as smart TVs, mobile phones, tablet computers, and all-in-one machines. Coupled with the comprehensive coverage of wireless networks, using WiFi to surf the Internet anytime and anywhere has become an indispensable part of people's lives. Great convenience came. However, in the manufacturing process of WiFi products, it is necessary to calibrate and test the WiFi chip. With the rapid development of the Internet of Things industry, the market demand is also increasing. The most commonly used in the Internet of Things is the module of the WiFi protocol. A large number of comprehensive testers are required for the calibration of a large number o...
