Existing UWB RF module test systems often have problems such as large size, high cost, and lack of flexibility, which makes it difficult to meet the rapidly changing market needs and diverse test scenarios. Especially in the production process of integrated circuits (ICs) and products, the scalability, flexibility, and cost-effectiveness of the test system have become key considerations. Traditional UWB RF test systems usually use large equipment, which not only takes up a lot of space, but also has a fixed test configuration, making it difficult to adapt to the needs of different test items. In addition, the firmware update and test item replacement process is cumbersome and requires professional personnel to operate, which increases the complexity and time cost of the test. In a multi-site test environment, the scalability of the existing system is limited, and it is difficult to quickly add or reduce test modules to meet different production test needs. In addition, the existing test system often lacks sufficient interactivity and flexibility when performing application test items such as ranging and angle positioning. In the case of mobile testing or the need to switch different RF interfaces to complete wider angle and longer distance testing, the performance of the existing system is not satisfactory.

Overall, the test system of the present invention significantly reduces production test costs and improves test efficiency through its modular, flexible and intelligent design, while maintaining test accuracy and reliability, providing an innovative solution for the testing of UWB RF modules.

[0057] Example

[0058] The UWB test system achieves efficient RF testing capabilities through miniaturization and modular design. The system uses a single high-speed transmission interface to simplify hardware requirements and supports multiple communication protocols, such as COMPORT and SPI, to adapt to different test environments. Each module is designed with two to six RF interfaces, including at least two TRX RF interfaces and up to six RF interfaces (2TRX+4RX) to meet different test requirements. In addition, the system provides external or internal reference clock options to ensure test synchronization.

[0059] The system is suitable for transceiver loopback RF tests such as FT (factory test), SLT (system level test), reliability test, etc. The module is compact, about the size of a Rubik's Cube, and can provide multiple antenna options to meet the needs of ranging and angle positioning tests. The modules can be freely combined, each module is independently controlled, and the computer can run multiple modules simultaneously through multi-threading or multiple operating modes to achieve cost-effectiveness and efficiency improvement.

[0060] In terms of test applications, the system can perform a variety of RF application test items, including but not limited to chip production test, product production test, reliability test, distance test, angle positioning test, raw data analysis and other performance tests. These test items are implemented through firmware, which is convenient for fast download and update through high-speed transmission interface.

[0061] The system's module and firmware scalability is one of its core strengths. Using the following algorithms, the system can flexibly adapt and expand its testing capabilities as the number of modules and firmware diversity increase.

[0062] Module scalability algorithm: Mx=A / Ma, the system can calculate the maximum number of modules that can be supported based on power supply conditions. Mx is the maximum number of modules that can be supported, A is the total input current, and Ma is the peak current of a single module. For example, a USB HUB that provides 3A current can support up to 5 modules. If you increase the number of USB HUBs or reduce the peak current power consumption of the module, the module scalability will increase accordingly.

[0063] RF interface scalability algorithm: RFP=MxRFx or (A / Ma)RFx, allows the system to calculate the total number of RF interfaces based on the number of modules and the number of RF interfaces of each module. Among them, RFP is the total number of RF interfaces that can be supported, Mx is the maximum number of modules that can be supported, A is the total input current, Ma is the peak current of a single module, and RFx is the total number of RF interfaces of a single module.

[0064] Test item scalability algorithm: AP = MFx-MFs, calculate the number of test items that can be executed in parallel according to the diversity of firmware in the module. AP is the number of application test items that can be executed in parallel, MFx is the total number of modules with firmware, and MFs is the total number of modules with the same firmware.

[0065] In terms of reducing costs and increasing efficiency of the test system, the system is easy to maintain and plug-and-play. The small module design allows for flexible installation and can be stacked, arranged horizontally, vertically or in different positions, which is suitable for multi-site testing of IC or product production. This flexibility allows for the rapid addition or reduction of modules, further reducing production test costs. In addition, the modules can define their own tags and base stations to increase interactivity, which is suitable for application test projects such as ranging and angle positioning. The scalability of small modules and RF interfaces allows different RF interfaces to be switched during mobile testing to complete tests at a wider angle and longer distance, or to achieve more ideal test results through multi-module switching.

[0066] like Figures 1 to 5 As shown, the flexibility and scalability of the UWB test system of the embodiment are demonstrated.

[0067] Figure 1 The innovative design of the combination of module and firmware of the embodiment is demonstrated, wherein the module memory can be dynamically allocated according to different application projects. Figure 1 In the figure, a) shows the dynamic allocation of memory: the system can dynamically allocate memory according to the requirements of the RF interface to support the operation of the maximum number of modules. Among them, module M1 is equipped with 2 TRX RF interfaces and 2 RX RF interfaces, which are used to perform basic functions and application tests, such as transceiver loopback tests of chips and products. Bootloader is a component for system startup and firmware update, which initializes the module and loads basic function firmware. When testing the application firmware that requires 2 TRX and 4 RX RF interfaces, the system will download and update the application firmware, and use the remaining space in the memory to meet additional testing requirements. Figure 1 In the figure, b) shows the update allocation of the memory: the system can update and allocate memory resources for modules equipped with two TRX RF interfaces to adapt to different test requirements. Among them, the module loads the basic function firmware through the Bootloader, and downloads the application firmware as needed for application testing, such as using 2 TRX RF interfaces for chip or product transceiver loopback testing. When it is necessary to execute application firmware 3, which also uses 2 TRX RF interfaces for testing, the system will download and update it to the remaining space of the memory to ensure that the module can flexibly switch test items. This design allows the module to adapt to various test requirements, and by simply downloading and updating the firmware, it can achieve a quick response to different test items. The module's RF interface design supports different numbers of TRX and RX interfaces, further enhancing the adaptability of the system.

[0068] Figure 2 The flexibility of the module RF interface of the embodiment is demonstrated, and the application of the RF interface can be adjusted according to different test requirements. Each module can be equipped with up to six RF interfaces, including RX0, RX1, RX2, RX3, TRX1 and TRX2, and supports the selection of external or internal reference clocks. This design improves the diversity of testing.

[0069] Figure 3 The scalability of the multi-module and multi-firmware test system is demonstrated, realizing "one-to-many" scalability. The computer can be connected to multiple modules (M1 to M8) through a hub, and each module is equipped with different application firmware (APP1 to APP6). This configuration allows the system to run multiple test projects at the same time, and each module can be controlled independently to achieve parallel testing. In addition, the firmware between modules can be recycled. For example, the M4 and M5 modules can recycle the APP1 and APP3 firmware, which increases the flexibility and efficiency of the system. In addition, each module can be used for a variety of wired RF tests to meet diverse test needs and scenarios. Through the combination of multiple modules and multiple firmware, a variety of possibilities for wired RF testing are realized.

[0070] Figure 4 The configuration of the basic firmware transceiver loopback RF test of multiple modules and multiple sites is demonstrated. Through the USB Hub, the system can connect multiple modules M1, M2, M3, M4, etc. and assign them to different test sites, such as Figure 4 SITE1-8 shown in the figure. A configuration method in which one module is equipped for every two sites, for example, the M1 module can correspond to SITE1 and SITE2, the M2 module corresponds to SITE3 and SITE4, the M3 module corresponds to SITE5 and SITE6, the M4 module corresponds to SITE7 and SITE8, and so on, the Mx module corresponds to SITE (2x-1) and SITE (2x). Through this configuration, the system can achieve efficient management of multiple test sites. Each module is connected to the corresponding site through a radio frequency line, ensuring the efficiency and accuracy of the test.

[0071] Figure 5 Demonstrated multi-module multi-directional RF wireless testing. The module is not only suitable for wired testing, but also for wireless distance measurement and wireless angle measurement. Through the collaborative work of multiple modules (such as M1, M2, M3, M4), the system can achieve comprehensive coverage of wireless testing. This wireless testing capability provides a broader space for the application of UWB RF modules.

[0072] The UWB test system shown in the figure demonstrates its excellent flexibility in hardware configuration and software control. The system design allows users to quickly adjust module configuration and firmware according to different test requirements to achieve efficient and accurate RF testing.

[0073] In summary, compared with traditional technologies, the UWB test system of the present invention can significantly reduce production test costs and improve test efficiency through its modular, flexible and intelligent design, while maintaining the accuracy and reliability of the test, providing an innovative, efficient and low-cost solution for the testing of UWB RF modules.
