[0053] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0054] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of the radio frequency test equipment in the hardware operating environment involved in the embodiment of the present invention.

The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may optionally be a storage device independent of the aforementioned processor 1001.

[0056] Those skilled in the art will understand that Figure 1The structure shown in the figure does not constitute a limitation to the radio frequency test equipment, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0057] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a radio frequency test program.

[0058] exist Figure 1 In the RF test device shown, the network interface 1004 is mainly used for data communication with the network integration platform workstation; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the RF test device of the present invention can be set in the RF test device, and the RF test device calls the RF test program stored in the memory 1005 through the processor 1001 and executes the RF test method provided by the embodiment of the present invention.

[0059] Based on the above hardware structure, an embodiment of a radio frequency testing method of the present invention is proposed.

[0060] Reference Figure 2 , Figure 2 FIG. 1 is a flow chart of a first embodiment of a radio frequency testing method according to the present invention.

[0061] In a first embodiment, the radio frequency testing method includes the following steps:

[0062] Step S10: determining the radio frequency received signal strength indicator data of the first device under test.

[0063] It should be noted that the execution subject of this embodiment is a radio frequency test device, and it can also be other devices that can achieve the same or similar functions, such as a radio frequency test system, etc. This embodiment does not limit this. In this embodiment, the radio frequency test system is used as an example for explanation.

[0064] Understandably, the reference Figure 3 , Figure 3 This is a schematic diagram of an RF test system, which specifically includes multiple DUTs, a PC terminal, and a path loss channel. The multiple DUTs and the path loss channel constitute an RF shielding box. Two DUTs are used as an example for illustration. For example, a first DUT and a second DUT, that is, the RF signal transmitted by the first DUT to the first DUT or the RF signal transmitted by the second DUT to the first DUT both need to pass through the path loss channel.

[0065] It should be understood that the RF received signal strength indication data refers to the indication data of the first device under test receiving the RF signal transmitted by the standard device, and the RF received signal strength indication data can be directly read after the first device under test receives the RF signal.

[0066] Furthermore, step S10 includes: after detecting that the first device under test receives the radio frequency signal transmitted by the standard component, reading radio frequency received signal strength indication data of the first device under test.

[0067] It is understandable that after the standard component transmits the RF signal, the RF signal will pass through the path and then be received by the first device under test, and then the RF received signal strength indication data of the first device under test will be read, that is, the RF received signal strength indication data of the first device under test can be obtained through the RF signal transmitted by the standard component.

[0068] Step S20 , determining the RF transmission power error and the RF received signal strength indication error of the first device under test according to the RF parameters of the standard component, the RF transmission power of the first device under test, and the RF received signal strength indication data.

[0069] It can be understood that the RF parameters refer to the parameters of the RF signal transmitted by the standard component. The RF parameters of the standard component include but are not limited to the actual transmission power, RF received signal strength indication data, etc. The RF transmission power error of the first device under test refers to the error of the RF signal transmitted by the first device under test with a specified power. The RF received signal strength indication error of the first device under test refers to the error of the strength indication of the RF signal received by the first device under test.

[0070] Step S30 : Compensating the RF transmission power and RF received signal strength indication data of the first device under test according to the RF transmission power error and the RF received signal strength indication error.

[0071] It should be understood that after obtaining the RF transmission power error and the RF received signal strength indication error, the RF transmission power of the first device under test is compensated according to the RF transmission power error, and the RF received signal strength indication data is compensated according to the RF received signal strength indication error. After the compensation is completed, the first device under test can be used as a standard part to perform RF testing on other devices under test.

[0072] Further, step S30 includes: determining a transmission power compensation value of the first device under test based on the RF transmission power error; compensating the RF transmission power of the first device under test based on the transmission power compensation value; determining a RF received signal strength indication compensation value of the first device under test based on the RF received signal strength indication error; and compensating the RF received signal strength indication data of the first device under test based on the RF received signal strength indication compensation value.

[0073] It can be understood that the transmission power compensation value refers to the value used to compensate the RF transmission power of the first device under test. After the compensation is completed according to the transmission power compensation value, the RF transmission power error of the first device under test can be offset. The RF received signal strength indication compensation value refers to the value used to compensate the RF received signal strength indication data of the first device under test. After the compensation is completed according to the RF received signal strength indication compensation value, the RF received signal strength indication error of the first device under test can be offset.

[0074] Step S40 , performing a radio frequency test on the second device under test by using the first device under test after compensating the radio frequency transmission power and the radio frequency received signal strength indicator data.

[0075] It can be understood that the first device under test after compensating for the RF transmission power and the RF received signal strength indication data can be used as a standard part, that is, the second device under test is subjected to RF testing by using the first device under test after compensating for the RF transmission power and the RF received signal strength indication data, so as to avoid defects such as damage and consumption of the standard part caused by using the same standard part to test other devices under test, thereby reducing the cost of RF testing.

[0076] Furthermore, after step S40, the method further includes: if there is a third device under test that needs to be tested for RF, determining the transmission power error and the RF received signal strength indication data error of the second device under test; compensating the RF transmission power and RF received signal strength indication data of the second device under test according to the transmission power error and the RF received signal strength indication data error of the second device under test; performing RF testing on the third device under test using the second device under test that has been compensated for the RF transmission power and the RF received signal strength indication data; if there are other components that need to be tested for RF, repeating the above steps of determining the transmission power error and the RF received signal strength indication data error until all components have completed the RF test.

[0077] It should be understood that after testing the second DUT, it is determined whether there is a third DUT that requires RF testing. If so, it indicates that the third DUT still needs to be RF tested. At this time, the second DUT is tested in the same manner as the RF test of the second DUT is performed using the first DUT. Specifically, the RF transmission power and RF received signal strength indication data of the second DUT are compensated based on the transmission power error and RF received signal strength indication data error of the second DUT. The second DUT that has been compensated for the RF transmission power and RF received signal strength indication data performs RF testing on the third DUT. After the test is completed, it is determined whether there are other components that require RF testing. If so, the above steps of determining the transmission power error and RF received signal strength indication data error are repeated until all components have completed RF testing.

[0078] For ease of understanding, refer to Figure 4 , Figure 4 The figure is a schematic diagram of the overall process, which is explained by taking a standard part and three DUTs as examples, namely the first DUT1, the second DUT2 and the third DUT3. The RF test of this embodiment includes a power test and a bit error rate test. First, the power test and the bit error rate test are performed on the first DUT1 through the selected standard part, and then the RF transmission power and the RF received signal strength indication data of the first DUT1 are compensated according to the RF transmission power error and the RF received signal strength indication error of the first DUT1. After the compensation is completed, the first DUT1 can be used as a standard part to perform power test and bit error rate test on the second DUT2, and then the RF transmission power error and the RF received signal strength indication data of the second DUT2 are compensated according to the RF transmission power error and the RF received signal strength indication error of the second DUT The RF transmission power and RF received signal strength indication data of the second device under test DUT2 are compensated according to the error in the RF transmission power and the error in the RF received signal strength indication of the third device under test DUT3. After the compensation is completed, the second device under test DUT2 can be used as a standard component to perform power testing and bit error rate testing on the third device under test DUT3. Then, the RF transmission power and RF received signal strength indication data of the third device under test DUT3 are compensated according to the error in the RF transmission power and the error in the RF received signal strength indication of the third device under test DUT3. After the compensation is completed, the third device under test DUT3 can also be used as a standard component to perform power testing and bit error rate testing on other components that need to be tested on RF. Performing RF testing on multiple devices under test in a progressive manner can avoid defects such as damage and consumption of standard components caused by always using the same standard component to test other devices under test.

[0079] This embodiment determines RF received signal strength indication data of a first device under test; determines an RF transmission power error and an RF received signal strength indication error of the first device under test based on RF parameters of a standard component, the RF transmission power of the first device under test, and the RF received signal strength indication data; compensates the RF transmission power and the RF received signal strength indication data of the first device under test based on the RF transmission power error and the RF received signal strength indication error; and performs an RF test on a second device under test using the first device under test after compensating for the RF transmission power and the RF received signal strength indication data. In this manner, the RF transmission power error and the RF received signal strength indication error of the first device under test are determined, and then the first device under test is compensated to be a standard component based on the RF transmission power error and the RF received signal strength indication error; and then the compensated first device under test is used to perform an RF test on the second device under test, thereby effectively reducing the cost of RF testing and improving the accuracy of RF testing.

[0080] In one embodiment, if Figure 5Based on the first embodiment, a second embodiment of the radio frequency testing method of the present invention is proposed. Step S20 includes:

[0081] Step S201: obtaining the actual transmission power of the standard component according to the radio frequency parameters of the standard component.

[0082] It should be understood that the actual transmission power of the standard component refers to the actual power of the radio frequency signal transmitted by the standard component to the first device under test. For example, the actual transmission power of the standard component is P(set).

[0083] Step S202 : determining the radio frequency transmission power error and the radio frequency received signal strength indicator error of the standard component according to the radio frequency parameters of the standard component.

[0084] Furthermore, step S202 includes: obtaining the actual transmit power of the RF transmitter and the actual RF received signal strength indication data of the RF receiver based on the RF parameters of the standard component; obtaining a preset transmit power threshold and a RF received signal strength indication threshold; calculating the RF transmit power error based on the actual transmit power of the RF transmitter and the preset transmit power threshold; and calculating the RF received signal strength indication error of the standard component based on the actual RF received signal strength indication data of the RF receiver and the RF received signal strength indication threshold.

[0085] It can be understood that the standard parts include an RF transmitter and an RF receiver. The selected standard parts need to ensure that the RF transmitter and receiver are in good condition, the actual transmission power of the RF transmitter is close to the preset transmission power threshold, and the actual RF received signal strength indication data of the RF receiver is close to the RF received signal strength indication threshold. The similarity measurement condition is that the RF transmission power error and the RF received signal strength indication error are less than or equal to the preset error threshold. For example, the actual transmission power of the RF transmitter is P0(test) and the preset transmission power threshold is P0. Then the RF transmission power error of the standard part ΔT0=P0(test)-P0, the actual RF received signal strength indication data of the RF receiver is R0(test), and the RF received signal strength indication threshold is R0. Then the RF received signal strength indication error of the standard part is ΔR0=R0(test)-R0.

[0086] Step S203 : calculating the transmission power of the radio frequency signal according to the actual transmission power of the standard component and the radio frequency transmission power error.

[0087] It can be understood that after obtaining the RF transmission power error, the transmission power of the RF signal is calculated based on the actual transmission power of the standard component and the RF transmission power error. For example, the actual transmission power of the standard component is P(set) and the RF transmission power error is ΔT0, then the transmission power of the RF signal P = P(set) + ΔT0.

[0088] Step S204 : Calculating the RF received signal strength indication error of the first device under test according to the transmission power of the RF signal and the numerical value corresponding to the RF received signal strength indication data.

[0089] It should be understood that after calculating the transmission power of the RF signal, the RF received signal strength indication error of the first device under test is calculated based on the transmission power of the RF signal and the numerical value corresponding to the RF received signal strength indication data. For example, if the numerical value corresponding to the RF received signal strength indication data is R1(test), then the RF received signal strength indication error of the first device under test ΔR1=R1(test)-P.

[0090] Step S205 : determining the radio frequency transmission power error of the first device under test according to the radio frequency received signal strength indicator error of the standard component.

[0091] Furthermore, step S205 includes: after detecting that the standard component receives the RF signal transmitted by the first device under test, reading the RF received signal strength indication data of the standard component; obtaining the path loss data of the RF signal transmitted from the first device under test to the standard component; and calculating the RF transmission power error of the first device under test based on the RF received signal strength indication data of the standard component, the RF received signal strength indication error of the standard component, and the path loss data.

[0092] It should be understood that the path loss data refers to the loss data of the RF signal emitted by the first device under test transmitted from the first device under test to the standard device through the path loss channel. The RF received signal strength indication data of the standard device and the RF received signal strength indication error of the standard device are then combined to calculate the RF received signal strength indication error of the first device under test. For example, the RF received signal strength indication data of the standard device is R01, the RF received signal strength indication error of the standard device is ΔR0, the path loss data is L, and the transmission power of the first device under test is P1, then the RF received signal strength indication error of the first device under test ΔT1=R01+ΔR0+L-P1.

[0093] This embodiment obtains the actual transmit power of the standard component based on the RF parameters of the standard component; determines the RF transmit power error and the RF received signal strength indication error of the standard component based on the RF parameters of the standard component; calculates the transmit power of the RF signal based on the actual transmit power of the standard component and the RF transmit power error; calculates the RF received signal strength indication error of the first device under test based on the transmit power of the RF signal and the numerical value corresponding to the RF received signal strength indication data; and determines the RF transmit power error of the first device under test based on the RF received signal strength indication error of the standard component. In this manner, the transmit power of the RF signal is calculated based on the actual transmit power of the standard component and the RF transmit power error, and then the RF received signal strength indication error of the first device under test is calculated in combination with the numerical value corresponding to the RF received signal strength indication data, and the RF transmit power error of the first device under test is determined based on the RF received signal strength indication error of the standard component, thereby effectively improving the accuracy of determining the RF received signal strength indication error and the RF transmit power error of the first device under test.

[0094] In addition, an embodiment of the present invention further provides a storage medium, on which a radio frequency test program is stored. When the radio frequency test program is executed by a processor, the steps of the radio frequency test method described above are implemented.

[0095] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0096] In addition, refer to Figure 6 , an embodiment of the present invention further provides a radio frequency testing device, the radio frequency testing device comprising:

[0099] The compensation module 20 is configured to compensate the RF transmission power and the RF received signal strength indication data of the first device under test according to the RF transmission power error and the RF received signal strength indication data error.

[0100] The testing module 30 is configured to perform a radio frequency test on the second device under test by using the first device under test after compensating the radio frequency transmission power and the radio frequency received signal strength indicator data.

In this manner, the RF transmission power error and the RF received signal strength indication error of the first device under test are determined, and then the first device under test is compensated to be a standard component based on the RF transmission power error and the RF received signal strength indication error; and then the compensated first device under test is used to perform an RF test on the second device under test, thereby effectively reducing the cost of RF testing and improving the accuracy of RF testing.
