The frequency offset adjustment module 413, the fine frequency offset synchronization module 414, the descrambling module 415, and the decoding module 416 are connected; the input switch array 4013 and the output switch array 4014 are respectively connected to the frequency offset adjustment module 405, the baseband frame parsing module 406, the deinterleaving module 407, the demodulation module 408, the time synchronization module 409, the equalization module 411, the phase synchronization module 412, the carrier recovery module 413, the fine frequency offset synchronization module 414, the descrambling module 415, and the decoding module 416; the input switch array 4013 and the output switch array 4014 are linked with the data stream sequence switch matrix 4015 to call the corresponding test algorithm module according to the data acquisition node and configure the connection order of each algorithm module.
[0045] In this embodiment, the data flow connection configuration module 401 consists of a branching interface 4011, a combining interface 4012, an input switch array 4013, and an output switch array 4014. The input switch array 4013 and the output switch array 4014 are composed of several gating components. Each gating component has three connection points, for example, points A, B, and C, and four connection methods: AB connection, BC connection, CA connection, and no connection between them, thus forming a flexible gating switch matrix. The input switch array 4013 and the output switch array 4014 have the same function. The data flow sequential switch matrix 4015 includes several switch nodes, enabling the connection and disconnection between the input switch array 4013, the output switch array 4014, and the algorithm module.
[0046] The branch interface 4011 is used to receive test data, inputting the test data to each gating component of the input switch array 4013. The combiner interface 4012 is connected to each gating component of the output switch array 4014, and can output the data processing results to the host computer 600.
[0047] In this embodiment, the input switch array 4013 is connected to the input terminal of the algorithm module, and the output switch array 4014 is connected to the output terminal of the algorithm module. The data flow sequence switch matrix 4015 is linked with the input / output switch matrix. When the input and output of each algorithm module can form a path through the input / output switch matrix, the data flow sequence switch matrix 4015 automatically connects the corresponding node. This establishes a path for the connection of the algorithm modules. The data processing unit 400, through the selection of various baseband processing algorithm modules and the flexible configuration of the connection order between algorithm modules, can adapt to the reception testing and debugging requirements of corresponding signal systems. The host computer 600 is responsible for debugging, analyzing, and evaluating the data processing results and finally outputting the test results. In addition, the data processing unit 400 can call the corresponding test algorithm module according to the selected node and can flexibly configure the connection topology between modules, thereby constructing a customized test architecture adapted to each node of the device under test 700. In this way, not only is the overall performance of the satellite baseband system verified systematically, but it can also serve R&D and debugging scenarios: by dynamically switching data acquisition nodes, abnormal links inside the baseband can be accurately located, significantly improving fault diagnosis efficiency and parameter optimization capabilities, and providing multi-dimensional testing support with both depth and breadth for the baseband under test.
[0048] Taking four algorithm modules as an example (algorithm module 1, algorithm module 2, algorithm module 3, and algorithm module 4), each algorithm module has an input terminal In and an output terminal Out. The corresponding input switch array 4013 and output switch array 4014 each have four selection switch components. The data stream sequence switch array has four signal paths (C1, C2, C3, C4) horizontally and four signal paths (R1, R2, R3, R4) vertically. By configuring the input switch array 4013 and the output switch array 4014, the connection path between algorithm modules 1, 2, and 3 can be established, thus not only selecting the algorithm modules used but also determining their sequential order.

After buffering and parallel-to-serial conversion, the data is sent to the second integrated interface driver module 310 for transmission. The second integrated interface driver module 310 provides drivers for various commonly used high-speed interfaces 300 for the DUT 700. Supported interface types include 10 / 100BASE-T Ethernet interface, 1000BASE-T Ethernet interface, Small Form-factor Pluggable Plus (SFP) interface, Quad Small Form-factor Pluggable Plus (QSFP) interface, and Optical-Copper Link (OCuLink) high-speed direct connection interface, adapted according to the hardware interface of the baseband receiver under test.

[0057] In some embodiments, such as Figure 1 and Figure 2As shown, the host computer 600 includes a debugging and analysis area 610, a function setting area 620, and a test and evaluation area 630.

The function setting area 620 is used to display and dynamically adjust parameters. The test and evaluation area 630 is used to generate test reports and monitor the status of the device under test 700 in real time.
[0058] In this embodiment, the host computer 600 includes a debugging and analysis area 610, a function setting area 620, and a test and evaluation area 630. The test and evaluation area 630 performs a full-function performance evaluation, automatically generates a test report, and monitors the status of the device under test 700 in real time. It includes two parts of information: status monitoring information and a test report. The status monitoring information has two types: demodulation and decoding monitoring information and modulation and coding monitoring information. The demodulation and decoding monitoring information displays the signal processing modules used by the receiver and their connection order in icon form. The status is displayed in the upper right corner of the page, and the status information includes frame synchronization lock, carrier lock, time synchronization lock, power display, frequency offset, total number of frames, number of misaligned frames, frame error rate (FER), modulation and coding combination (MODCOD), normalized signal-to-noise ratio (Eb / N0), etc.

During the hardware execution test process, the software monitors the system status in real time, extracts relevant data for the test items, and automatically compiles and generates a single test report.
[0061] Customized continuous test reports refer to the process where, after the software is set to this mode, the test signal generation unit 100 (i.e., the excitation source of the device under test 700) generates customized continuous test reports. Examples include testing the frame error rate (FER) of the device under test 700 at different symbol rates and the signal-to-noise ratio (Eb / N0) of the device under test 700 at different transmit powers. Specifically, in real-time, the parameter configuration module needs to set the test items to be displayed in the test report, configure the range and step values of the relevant variables of the excitation source, and set the duration of each test segment. The excitation source automatically and continuously adjusts the parameters according to the configuration to perform the test. Finally, the test data is integrated and output in a structured table format to form a complete customized continuous test report.

This module captures timing characteristics with high precision, enabling rapid diagnosis of timing logic errors in the device under test 700 and significantly improving fault location efficiency. The signal spectrum analysis module 612 possesses the basic functions of a spectrum analyzer (such as FFT transformation, window function selection, and amplitude / phase spectrum display), supporting frequency domain characteristic analysis of the measured signal (e.g., noise distribution, harmonic distortion detection). The data calculation and statistics module 613 provides basic statistical operation functions, including summation, mean, standard deviation, and variance calculations, facilitating real-time analysis of test data by users. The custom algorithm simulation module 614 can be built based on the MATLAB engine, allowing users to import and run custom algorithms to achieve real-time comparison between actual hardware operating data and theoretical simulation results (such as algorithm convergence verification or error analysis), thus enabling users to analyze and evaluate the algorithm of the device under test 700.

The function module parameter configuration provides detailed parameter configuration subpages for all modules in the test signal generation unit 100, all modules in the data processing unit 400, and all modules in the time-frequency matching unit 200. Subpage configuration items provide a storage function, allowing users to recall stored configuration parameters to simplify operations. After the configuration parameters are fully set, the configured parameters will be displayed on the right side of the configuration page in a grayed-out, uneditable format.

Next, set the test items, which correspond to the specific test items in the test report (such as signal-to-noise ratio, bit error rate, error vector magnitude (EVM), etc.); configure the signal generation unit parameters (including data source selection, clock configuration, modulation scheme selection, transmitted signal amplitude / phase, channel coding scheme, etc.); set the interface rate matching parameters, which are adapted to the 8-channel parallel architecture of this test and evaluation device based on the number of parallel channels inside the DUT's FPGA; configure the data flow parameters of the data processing unit (including the selection of the required analysis algorithm modules (multiple selections are supported) and the setting of their processing flow order).
[0067] After setting the parameters, start the test process. First, select a debugging and analysis tool (options include spectrum analysis, logic analysis, data statistics, custom Matlab algorithm analysis, etc.). After the data analysis is completed, the raw data and analysis results can be stored. If the test mode is continuous data acquisition, the parameters of the signal generation unit and data processing unit can be adjusted in real time, and the test can be restarted to achieve real-time online debugging and analysis. Before the test starts, the test report generation process can be configured and enabled synchronously (supporting single test or continuous test report modes). After the test starts, the test data will be automatically stored according to the test items, and test reports will be generated synchronously. The host computer supports online viewing and export of test reports.
