Detailed Description
The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.
It is to be noted that the experimental methods described in the following embodiments are all conventional methods unless otherwise specified, and the reagents and materials described therein are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
Some of the words referred to herein are described below to facilitate understanding by those skilled in the art.
A radio frequency transceiver: the radio frequency signal is a high-frequency alternating current electromagnetic wave which can be transmitted in the air and reflected by an ionized layer at the outer edge of the atmosphere, and has long-distance transmission capability.
A radio frequency test board: the circuit board is used for testing the radio frequency transceiver, and the radio frequency transceiver to be tested is integrated on the circuit board to form a radio frequency transceiver module which can execute the functions of radio frequency signal generation, radio frequency signal transmission and radio frequency signal receiving.
EVM: error Vector, which includes vectors of amplitude and phase, is the Vector difference between an ideal Error-free reference signal and an actual transmitted signal at a given time, and can comprehensively measure the amplitude Error and the phase Error of a modulated signal. The EVM specifically indicates the closeness of an IQ component generated when a transmitter demodulates a signal to an ideal signal component, and is an index for considering the quality of a modulated signal.
ACPR (acid reaction: the ratio of the average power of the adjacent frequency channels (or offsets) to the average power of the transmit frequency channels.
An information source comprehensive tester: the wireless mobile communication parameter testing instrument can generate 3G, 4G, 5G, Wifi and other information sources. According to different manufacturers, the parameter indexes tested by the tester are different, and most of the comprehensive testers can check the indexes of wireless signals, such as EVM, output power, ACPR and the like.
As mentioned above, there are two main ways for testing the rf transceiver in the prior art, one is laboratory testing, which uses a precise instrument such as a spectrum analyzer or a comprehensive tester to perform testing, and the characteristics of the instrument can be used to more accurately, finely and comprehensively test the rf transceiver. However, the operation is completely carried out manually, so the professional requirement is high and the efficiency is low. The other is factory testing, which uses professional testing equipment and has high testing efficiency, but is inflexible and expensive. And the whole periodic process from the development of radio frequency transceivers to the large-batch generation has the requirement of small-batch generation. For the generation of small batches, if factory testing is directly adopted, the risk is high, because a radio frequency transceiver may have problems in the testing process, the radio frequency transceiver needs to be perfected, the cost for directly customizing factory testing is too high, and the cost is too high if subsequent changes are made; however, if a laboratory test is adopted, the efficiency is too low, because the laboratory test adopts precision instruments such as a spectrum analyzer or a comprehensive tester, the obtained detection result is a specific value of each test index, and a worker needs to analyze the detection result of each radio frequency transceiver to judge the product quality, so that the analysis of the detection result of each radio frequency transceiver consumes time and energy, and the efficiency is low.
In view of the above analysis, it is seen that the main problem of the prior art is that there is no fast, simple and low-cost test method for testing small batches of radio frequency transceivers. In the application, it is mainly considered that a detection device (such as an information source comprehensive tester) generally has a plurality of detection interfaces, and actually, a plurality of radio frequency transceivers can be simultaneously detected, so that only the statistical analysis of detection results needs to be performed by one worker, and the small-batch test cannot be realized. The embodiment of the application provides a low-cost technical scheme for batch testing of radio frequency transceivers, and the upper computer is used for carrying out statistical analysis on the detection result obtained by each interface on the detection equipment to replace the manual work to complete the task, so that the small-batch testing is realized, and meanwhile, the high-price customized testing is not needed.
Further, the technical scheme of the low-cost batch test of the radio frequency transceivers provided by the embodiment of the application can be applied to the design test process of the radio frequency transceivers or the design test process of the production process of the radio frequency transceivers.
