System and method for testing multiple wireless radio frequency modules

Abstract

A system for testing multiple wireless radio frequency modules is used for testing the wireless radio frequency modules in the same working mode, and comprises a radio frequency signal analyzer, a radio frequency exchanger, a control module and a plurality of testing modules, wherein the radio frequency exchanger is electrically connected with the radio frequency signal analyzer; a working frequency range of the radio frequency exchanger comprises a plurality of frequency ranges of the wireless radio frequency module for transmitting and receiving radio frequency signals; the control module controls the radio frequency signal analyzer and the radio frequency exchanger; the testing modules are electrically connected with the control module and controlled by the control module; each testing module is provided with a storage unit for storing testing results; and the radio frequency exchanger and the testing modules allow each wireless radio frequency module to be electrically connected between the radio frequency exchanger and each testing module. The system and method for testing the wireless radio frequency modules are used for testing the wireless radio frequency modules simultaneously, so that the testing time and testing cost are saved.

Description

technical field [0001] The invention relates to a radio frequency test system, in particular to a test system and a method for testing multiple groups of radio frequency modules. Background technique [0002] Due to the advancement of wireless communication technology, electronic devices installed with radio frequency modules can utilize existing wireless frequency bands or wireless communication architectures to transmit or receive data (or signals). Furthermore, the current bandwidth for wireless transmission or reception of data is gradually approaching the bandwidth of a traditional Ethernet network (Ethernet), so wireless communication has been received and used by a large number of users. For example, Bluetooth (Bluetooth), Wireless Fidelity (WiFi) and Global Positioning System (GPS) are often used. For now, the radio frequency module of the communication device still accounts for a major part of the cost of the communication device, and the quality and efficiency of ...

AI Technical Summary

Problems solved by technology

However, RF signal analyzers are expensive for manufacturers, and the number of RF modules that each RF signal analyzer can test at the same time is often limited by the number of output / input interfaces of the RF signal analyzer

Therefore, using a radio frequency signal analyzer to test a large number of radio frequency modules may have problems such as excessive test time and increased test cost
