Referring to fig. 1 and fig. 2, a method for testing the receiving sensitivity of an electronic device according to an embodiment of the present invention can be implemented by a system 100 for testing the receiving sensitivity of an electronic device according to an embodiment of the present invention. Test system 100 includes an electronic device under test 10 and a test device 20. The electronic device under test 10 comprises a test circuit 12, an antenna 14, and a radio frequency receiver 16. Test circuit 12 includes a first branch 122, a second branch 124, and a third branch 126 connected to each other. The first branch 122 is connected to the antenna 14, the second branch 124 is connected to the radio frequency receiver 16, and the third branch 126 is connected to the test equipment 20.
Referring to fig. 1, a method for testing the receiving sensitivity of an electronic device according to an embodiment of the present invention includes:
step S12: when the first branch 122, the second branch 124 and the third branch 126 are all provided with preset resistors, acquiring a first signal error rate of the electronic device 10 to be tested and determining a first receiving sensitivity according to the first signal error rate;
step S14: when the second branch 124 and the third branch 126 are both provided with preset resistors, obtaining a second signal error rate of the electronic device 10 to be tested and determining a second receiving sensitivity according to the second signal error rate;
step S16: when the absolute value of the difference between the first receiving sensitivity and the second receiving sensitivity is larger than the first threshold value, it is determined that interference signals are introduced through the antenna 14 to affect the receiving performance of the tested electronic device 10.
According to the method for testing the receiving sensitivity of the electronic equipment, interference introduced by the antenna 14 is taken into consideration, and whether interference signals are introduced through the antenna 14 to influence the receiving performance of the electronic equipment 10 to be tested can be determined by comparing the first receiving sensitivity with the second receiving sensitivity, so that the accuracy and the reliability of the test are improved.
It is understood that the electronic device 10 under test generally includes a usb (universal Serial bus) module, and/or a pcie (peripheral component interconnect express) module, and/or a ddr (data Direction register) module. The USB signal generated when the USB module works, the PCIE signal generated when the PCIE module works, and the DDR signal generated when the DDR module works easily interfere with the antenna 14, so that the receiving performance of the electronic device 10 to be tested is affected. In the related art, the output end of the test equipment is directly connected with the input end of the tested electronic equipment, and interference signals introduced by an antenna of the tested electronic equipment are not considered, so that the receiving sensitivity test of the tested electronic equipment is inaccurate.
In order to improve the accuracy and reliability of the reception sensitivity test, in the embodiment of the present invention, the interference signal introduced through the antenna 14 is introduced into the test link through the first branch 122, and the reception sensitivity test with the antenna 14 is implemented. In step S12, the interference signal of the electronic device under test 10 includes the interference signal introduced through the antenna 14, and in step S14, the interference signal of the electronic device under test 10 does not include the interference signal introduced through the antenna 14. Therefore, by comparing the first receiving sensitivity and the second receiving sensitivity, it can be known whether there is an interference signal introduced into the electronic device under test 10 through the antenna 14.
In the embodiment of the present invention, the electronic device 10 to be tested includes a mobile phone, a wireless router, a tablet computer, a notebook computer, etc. The electronic device under test 10 may comprise one antenna 14, two or more antennas 14. For example, the electronic device 10 to be tested is a 2 x 2MIMO product, comprising two antennas 14, and correspondingly, two receiving paths. For example, the electronic device 10 to be tested is a 3 × 3MIMO product, and includes three antennas 14, and correspondingly, three receiving paths. For example, the electronic device 10 under test is a 4 × 4MIMO product, and includes four antennas 14, and correspondingly, four receiving paths.
Each receiving path is provided with a test circuit 12 to test the receiving sensitivity of the electronic device 10 under test under different working conditions. It will be appreciated that the electronic device under test 10 comprising a plurality of antennas 14 may be operated with one antenna 14 or with two or more antennas 14 operating simultaneously. In the example of fig. 2, the electronic device under test 10 is a 2 x 2MIMO product, comprising two antennas 14 and two receive paths. Each receive path is provided with a test circuit 12. In the reception sensitivity test, the reception sensitivity of each antenna 14 when operating alone is separately tested, and the reception sensitivity of two antennas 14 when operating simultaneously is tested.
In one example, the electronic device under test 10 includes a USB module, a PCIE module, and a DDR module. When the receiving sensitivity test is performed, the USB module, the PCIE module, and the DDR module may all be controlled to be in a working state to obtain an interference condition of the tested electronic device 10 under the limit working condition.
In the embodiment of the present invention, the test circuit 12 is a T-type network structure. After the T-type network circuit is introduced into the test link, the first reception sensitivity measured at step S12 has an attenuation of 3 db. Therefore, the second reception sensitivity measured in step S14 needs to be reduced by 3db before being compared with the first reception sensitivity. Wherein the first threshold may be 1 db. Of course, the first receiving sensitivity measured in step S12 and the second receiving sensitivity measured in step S14 may be directly compared with each other, and the first threshold may be set to 4 db. The first threshold may be other values, which is not limited in this embodiment.
In the embodiment of the invention, the preset resistor is a zero-ohm resistor and plays a role of direct signal connection. If a predetermined resistor is not set in a certain resistor pad 121, it indicates that the corresponding branch path is cut off, and the signal is interrupted.
It should be noted that after the receiving sensitivity test is completed, the preset resistance of the third branch 126 in the test circuit 12 may be removed, that is, the third branch 126 is not provided with the preset resistance, and both the first branch 122 and the second branch 124 are provided with the resistance. In this way, radio frequency signals can be radiated to free space through the antenna 14, and the electronic device 10 to be tested can be used normally.
Referring to fig. 3, in some embodiments, before step S12, the testing method includes step S10: the radio frequency receiver 16 is controlled to operate in a preset bandwidth mode.
Preferably, in the present embodiment, the predetermined bandwidth is a maximum bandwidth. The maximum bandwidth is the maximum frequency bandwidth occupied by the signal that can be received by the rf receiver 16. Before the receiving sensitivity test is started, the radio frequency receiver 16 is controlled to work in the maximum bandwidth mode, so that the test channel can cover all the used frequency bands, and the reliability of the test result is improved.
In certain embodiments, the testing method comprises: and determining the source of the interference signal and the interference strength through a comparison test.
It can be understood that, after determining the source and the interference strength of the interference signal, the interference source may be processed in a targeted manner according to the interference strength, so as to further improve the receiving performance of the electronic device 10 to be tested.
In one example, the tested electronic device 10 includes a USB module, a PCIE module, and a DDR module, and it can be determined through two test comparisons that the interference signal originates from the USB module, or the PCIE module, or the DDR module, and the interference strength. During the first test, the USB module, the PCIE module, and the DDR module are all controlled to be in a working state, and when the first branch 122, the second branch 124, and the third branch 126 are all provided with the preset resistors, the signal error rate of the tested electronic device 10 is obtained, and the receiving sensitivity S1 is determined according to the signal error rate. During the second test, the PCIE module and the DDR module are controlled to be in the working state, the USB module does not work, and when the first branch 122, the second branch 124, and the third branch 126 are all provided with the preset resistors, the signal error rate of the tested electronic device 10 is obtained, and the receiving sensitivity S2 is determined according to the signal error rate. If S1 and S2 are the same, it is indicated that the source of the interference signal is not the USB module. If S1 is different from S2, it indicates that the USB module is one of the interference sources, and the interference strength generated by the USB module can be determined by the difference between S1 and S2. If the interference intensity is small, corresponding processing is not needed. If the interference intensity is higher, the interference generated by the USB module can be reduced by increasing a shielding cover, increasing wave-absorbing materials, strengthening grounding or changing the signal frequency of the USB module and the like.
In certain embodiments, step S12 includes: the first signal error rate is determined based on the number of data packets received by the rf receiver 16. Step S14 includes: the second signal error rate is determined based on the number of data packets received by the rf receiver 16.
It is understood that the test device 20 may be a signal emitting Source (e.g., IQ N × N SG Source) for emitting a plurality of data packets with a certain signal strength to the rf receiver 16 of the electronic device 10 under test. When an interfering signal is present, the radio frequency receiver 16 may not receive all of the data packets transmitted by the test equipment 20, and may lose some of the data packets. Therefore, the signal error rate of the tested electronic device 10 under the signal strength can be determined according to the number of the data packets received by the radio frequency receiver 16.
In certain embodiments, step S12 includes: monitoring the signal strength emitted by the test equipment 20 when the first signal error rate is greater than the second threshold; and determining a first receive sensitivity based on the signal strength. Step S14 includes: monitoring the signal strength emitted by the test equipment 20 when the second signal error rate is greater than a second threshold value; the second reception sensitivity is determined based on the signal strength.
It can be understood that when the signal error rate of the electronic device under test 10 exceeds the second threshold, the signal strength emitted by the testing device 20 at this time can be considered as the receiving sensitivity of the electronic device under test 10. For example, if the second threshold is 10%, and the error rate of the signal exceeds and approaches 10%, and correspondingly, the strength of the signal transmitted by the testing device 20 is-85 dbm, the receiving sensitivity of the electronic device 10 under test can be considered to be-85 dbm. The second threshold may be other values, which is not limited in this embodiment.
Referring to fig. 2, an electronic device receiving sensitivity testing system 100 according to an embodiment of the present invention includes an electronic device 10 to be tested, a testing device 20, a memory 30, and a processor 40. The electronic device under test 10 comprises a test circuit 12, an antenna 14, and a radio frequency receiver 16. Test circuit 12 includes a first branch 122, a second branch 124, and a third branch 126 connected to each other. The first branch 122 is connected to the antenna 14, the second branch 124 is connected to the radio frequency receiver 16, and the third branch 126 is connected to the test equipment 20. The memory 30 stores a computer program, and the processor 40 realizes the method for testing the reception sensitivity of the electronic device according to any of the above embodiments when executing the program.
According to the method for testing the receiving sensitivity of the electronic equipment, interference introduced by the antenna 14 is taken into consideration, and whether interference signals are introduced through the antenna 14 to influence the receiving performance of the electronic equipment 10 to be tested can be determined by comparing the first receiving sensitivity with the second receiving sensitivity, so that the accuracy and the reliability of the test are improved.
It should be noted that the explanation and the advantageous effects of the electronic device reception sensitivity testing method according to the above embodiment are also applicable to the electronic device reception sensitivity testing system 100 according to the present embodiment, and are not detailed here to avoid redundancy.
In the embodiment of the present invention, the memory 30 and the processor 40 may be a memory and a processor in the tested electronic device 10. Of course, the memory 30 and the processor 40 may also be provided in another separate device, such as a control device. That is to say the control device comprises a memory 30 and a processor 40. The control device connects the test device 20 and the radio frequency receiver 16.
In some embodiments, the first branch 122, the second branch 124, and the third branch 126 each include a resistance pad 121, and the resistance pad 121 is used to set a preset resistance.
It is understood that the predetermined resistor is soldered to the resistor pad 121. The predetermined resistance may be a zero ohm resistance.
In some embodiments, the test circuit 12 includes a microstrip line 128. The first branch 122, the second branch 124 and the third branch 126 are connected to each other by a microstrip line 128. The width of the resistance pad 121 coincides with the width of the microstrip line 128.
It is understood that the microstrip line 128 is a microwave transmission line, which can transmit microwave signals. The width of the resistance pad 121 is consistent with that of the microstrip line 128, so that the radio frequency impedance continuity can be ensured, and impedance sudden change is avoided.
In some embodiments, the test circuit 12 includes an antenna pad 123 and a radio frequency test pad 125. The first branch 122 is connected to an antenna pad 123 via a microstrip line 128, the antenna pad 123 being connected to the antenna 14. The second branch 124 is connected to the radio frequency receiver 16 by a microstrip line 128. The third branch 126 is connected to the rf test pad 125 via a microstrip line 128, and the rf test pad 125 is connected to the test equipment 20.
Further, the antenna pad 123 and the antenna 14 may be connected by a microstrip line 128 or may be connected by a coaxial line. Preferably, if the antenna 14 is an internal antenna, the antenna 14 is connected to the antenna pad 123 through the microstrip line 128; if the antenna 14 is an external antenna, the antenna 14 is connected to the antenna pad 123 through a coaxial line. The rf test pad 125 and the test equipment 20 are connected by a coaxial line.
It is understood that the antenna pads 123 may be replaced with antenna 14 receivers. The rf test pad 125 may be replaced with an rf test socket.
In some embodiments, the width of the rf test pad 125 corresponds to the width of the microstrip line 128. Therefore, the radio frequency impedance can be ensured to be continuous, and impedance sudden change is avoided.
It should be noted that, in the present invention, the impedance value of the rf receiver 16 is the same as the impedance value of the microstrip line 128. In one example, the impedance value of the rf receiver 16 and the impedance value of the microstrip line 128 are 50 ohms.
