BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0043] Figure 1 It is a schematic diagram of the system structure of the present invention. DETAILED DESCRIPTION

[0044] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0045] A repeater is a relay device used in wireless communication systems. It is mainly used for signal amplification and transmission to enhance signal coverage and signal quality. It receives high-frequency signals from base stations, amplifies, filters and then transmits them, thereby improving the coverage and communication quality of wireless networks. A repeater consists of multiple components, including antennas, RF duplexers, low-noise amplifiers, mixers, electrically adjustable attenuators, filters and power amplifiers. These components work together to receive, amplify and forward wireless signals. In the downlink, the repeater receives the signal from the base station through the donor antenna, amplifies it through the low-noise amplifier, filters out noise through the filter, and finally retransmits the signal to the coverage area through the power amplifier. In the uplink, the repeater receives the signal from the mobile station, and transmits it back to the base station after a similar processing process, thereby achieving two-way communication. Repeaters are widely used, especially in areas that are difficult to directly cover, such as shopping malls, hotels, airports, tunnels, highways and islands. In these places, repeaters can significantly improve communication quality and solve the problem of dropped calls. For example, in areas where signals are difficult to penetrate, such as underground shopping malls or subways, repeaters can effectively extend the coverage of base station signals and ensure smooth communication. As an important part of the wireless communication system, repeaters greatly improve the coverage and communication quality of the network through their signal amplification and transmission functions, and solve many signal blind spot problems. In the future development of communication networks, repeaters will continue to play an important role to meet the growing communication needs.

[0046] The automatic adjustment and testing system proposed in the present invention is designed for repeater products, has comprehensive RF index adjustment and testing capabilities, and has good compatibility, and can adapt to different types and specifications of repeater equipment. Regardless of whether it is for equipment of different frequency bands and different technical standards, the system can perform effective adjustment and testing, which is different from the traditional technology that only tests and can only be used for a single device. It can realize all-round adjustment of RF projects and functional projects, including output power including ALC power adjustment function, maximum gain, EVM, intermodulation, in-band fluctuation, out-of-band gain, noise factor, in-band background noise, in-band spurious, gain adjustment, power detection range and error, actual gain, attenuation, sub-band attenuation, RF switch, performance items including intelligent AGC function, uplink silence, etc. At the same time, the system can calibrate all instruments before adjustment and can perform self-excitation adjustment.
