The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0031] Figure 1 It is a flowchart of a radio frequency testing method for a satellite terminal proposed in an embodiment of the present disclosure.

[0032] It should be noted that the executor of the radio frequency testing method for a satellite terminal in this embodiment is a radio frequency testing device for the satellite terminal, which may be implemented in software and / or hardware.

[0033] like Figure 1 As shown, the radio frequency test method of the satellite terminal is applied to a control device, and the method includes:

[0034] S101: Obtain a radio frequency test case of a satellite terminal to be tested.

[0035] The control device refers to a device used to control the radio frequency test process in the satellite terminal radio frequency test system, such as a PC.

[0036] Satellite terminal refers to the equipment or device used to communicate with ground stations or other satellites in satellite communication systems. It is an indispensable component of satellite communication systems and is responsible for receiving and sending data, control information, etc. Satellite terminals can be various types of equipment, such as satellite phones, satellite modules, etc. The satellite terminal to be tested can refer to the satellite terminal to be tested for RF.

[0037] Among them, the RF test case is a standardized description of a set of inputs, execution conditions, expected results and execution steps used in the RF test process, which can be used to verify whether the RF system of the satellite terminal works according to the expected functions and requirements.

[0038] For example, the RF test case can be a transmitter performance test case configured for the above-mentioned satellite terminal to be tested, such as being used to test transmit power, output power dynamic range, error vector amplitude, carrier leakage, occupied bandwidth, adjacent channel leakage ratio, etc., or it can also be a receiver index test case, such as being used to test receiver sensitivity, maximum input level, adjacent channel selectivity, etc.

[0039] In the embodiment of the present disclosure, when obtaining the RF test case of the satellite terminal to be tested, a communication link between the execution subject of the embodiment of the present disclosure and the big data server can be established in advance, and then the RF test case is obtained from the big data server. Alternatively, the RF test case can be generated by a third-party device, and there is no limitation on this.

[0040] In the disclosed embodiment, when a radio frequency test case of a satellite terminal to be tested is obtained, a reliable execution basis can be provided for a radio frequency test process of the satellite terminal to be tested.

[0041] S102: Control the satellite terminal to be tested and the test equipment to execute radio frequency test cases based on a preset application program to obtain radio frequency test results.

[0042] The test equipment may refer to equipment used to perform radio frequency testing on a satellite terminal to be tested, and may include, for example, a signal shielding box, a test fixture, a power supply, a circulator, a signal source, a signal analyzer, etc., without limitation.

[0045] That is to say, the disclosed embodiment does not require the satellite terminal to be tested to access the network during the RF test process. Instead, the preset application directly controls the satellite terminal to be tested to execute the corresponding RF test steps, thereby effectively avoiding the testing costs brought about by the terminal accessing the network and improving the practicality of the RF testing method.

[0046] For example, in an embodiment of the present disclosure, a preset application may instruct the terminal to send an uplink signal or a downlink signal through a USB interface for terminal transmitter performance testing and receiver performance testing.

[0047] In this embodiment, by obtaining the RF test case of the satellite terminal to be tested, the satellite terminal to be tested and the test equipment are controlled to execute the RF test case based on the preset application to obtain the RF test result. Thus, the RF performance of the satellite terminal can be automatically tested based on the preset application, thereby improving the RF test efficiency and test accuracy while greatly reducing the test cost.

[0048] Optionally, in some embodiments, before obtaining the RF test case of the satellite terminal to be tested, the communication address of the test device and the storage address of the RF test results can be configured based on a preset application program to determine the connection status between the satellite terminal to be tested, the test device and the control device; if the connection status indicates that the satellite terminal to be tested, the test device and the control device are connected normally, a burning program driver is determined from a preset driver library, and the satellite terminal to be tested is program burned based on the burning program driver, wherein the burning program driver is used to enable the satellite terminal device to have corresponding RF test functions, thereby providing a reliable execution object for the RF test process, which can effectively ensure the reliability and practicality of the RF test process.

[0049] Among them, configuring the communication address of the test equipment may refer to configuring the serial port number, baud rate, etc. of the fixture driver, the IP address of the signal source and the signal analyzer, etc., and there is no restriction on this.

[0050] The storage address may be used to store the radio frequency test results obtained by the execution subject of the embodiment of the present disclosure. The storage address may be in the control device, or may be in a third-party storage medium, and there is no limitation on this.

[0051] The program programming driver may refer to a driver for programming an application processor (AP) program and / or a communication processor (CP) program of a terminal, for example, and there is no limitation to this.

[0052] Optionally, in some embodiments, after determining the connection status among the satellite terminal to be tested, the test equipment and the control equipment, if the connection status indicates that the connection among the satellite terminal to be tested, the test equipment and the control equipment is abnormal, fault detection and maintenance are performed, and a new connection status is determined. Thus, fault detection and maintenance can be performed in a timely manner when the connection among the satellite terminal to be tested, the test equipment and the control equipment is abnormal, so as to effectively improve the robustness of the RF testing process.

[0071] The runtime information may be used to describe the runtime order and execution logic of at least one target driver.

[0072] In the disclosed embodiment, when at least one target driver is determined from a plurality of candidate drivers included in a preset driver library according to test requirement information, and the operating timing information between at least one target driver is determined, reliable data support can be provided for subsequent RF test cases.

[0073] S206: Combine at least one target driver according to the runtime information to obtain a radio frequency test case.
