In this embodiment, the 5G base station 4 to be tested is generally provided with four radio frequency ports, and each radio frequency port has 1800MHz, 2300MHz, and 2600MHz carrier frequency bands at the same time.

Among them, 1800MHz and 2300MHz belong to 4G signal, and 2600MHz belongs to 5G signal. In the prior art, expensive special equipment is required to directly perform hardware test on the 5G signal, so the hardware test method of the embodiment is to use a common test instrument to perform test on the 4G signal. The hardware test mainly tests whether the radio frequency port of the 5G base station has short circuit or open circuit and the like, and whether the radio frequency signal can be normally sent. Because one rf port can transmit 4G and 5G signals simultaneously, if the test result of the 4G signal is good, it indicates that the rf port is normal, otherwise, the rf port cannot transmit the 4G signal and cannot transmit the 5G signal.

In this embodiment, the 5G base station 4 to be tested includes a digital processing module 41, an interface processing module 42, a photoelectric conversion module 43, a power supply module 44, a PHY interface 45, and a radio frequency output module 46, where one end of the digital processing module 41 is connected to the interface processing module 42, the other end of the digital processing module 41 is connected to the radio frequency output module 46, the interface processing module 42 is connected to the photoelectric conversion module 43, and the interface processing module 42 is connected to the PHY interface 45; the digital processing module 41, the interface processing module 42, the photoelectric conversion module 43, the PHY interface 45, and the rf output module 46 are electrically connected to the power supply module 44, and the rf output module 46 is connected to the rf port.

The clock module 47 is used for accurately timing other modules, and ensures time synchronization of each module.

In this embodiment, the test instrument 5 is a spectrum analyzer suitable for testing 4G signals, such as a spectrum analyzer of anli brand 332E model or a spectrum analyzer of de brand 9030B model, both of which can be used for testing 4G signals, and are cheaper and simpler to operate than a special 5G test instrument.

The test instrument 5 selects to test the 2300-frequency-band signal, and if the relevant waveform and information of the 2300 frequency band can be displayed on the display screen of the test instrument 5, it indicates that the hardware of the radio frequency port is normal. If the waveform displayed on the display screen of the test instrument 5 does not conform to the 2300 frequency band or cannot display the related waveform, it indicates that the hardware of the radio frequency port has a problem and needs to be overhauled.

In summary, the hardware test system of the 5G base station of the present invention determines whether the hardware line of the radio frequency port is normal by testing the 4G signal of the radio frequency port, and the miniaturized core network 1 can directly issue the configuration data of the normal operation mode without first issuing the configuration data of the test mode and then restoring, so that the test procedure can be simplified, and the test can be completed by using a common test instrument, thereby reducing the test cost and improving the test efficiency.
