Firstly, the method for measuring the equivalent isotropic radiated power of equipment proposed in the embodiment of the present application will be described in detail with reference to FIG. 1 .

Fig. 1 is a schematic flowchart of a method for measuring equivalent isotropic radiated power of a device according to an embodiment of the present application.

As shown in Figure 1, the equipment equivalent isotropic radiated power measurement method of the present application includes the following steps:

Step 101, adjust the position of the device under test to determine the target position of the device under test when the signal power received by the test device is at a maximum value.

Specifically, the equipment equivalent isotropic radiated power measurement method provided in the embodiment of the present application can be executed by the electronic equipment provided in the embodiment of the present application, and the equipment equivalent isotropic radiated power measurement device can be configured in the electronic equipment to realize the An accurate measurement of the equivalent isotropic radiated power of a device. Among them, there are many types of electronic devices, which can be selected according to application requirements, for example, mobile phones, computers, and the like.

Wherein, the device under test (Device Under Test, referred to as: DUT) may be any device with a radio frequency function, such as a wireless router, a smart phone, a tablet computer, and the like.

During specific implementation, data transmission can be performed between the device under test (the wireless DUT in Fig. 2 ) and the companion device (System Under Test, referred to as: SUT) according to the measurement scenario shown in Fig. 2, and the test device (The spectrum analyzer in Figure 2) receives the transmitted signal by the receiving antenna, so that the target position of the device under test can be determined when the signal power received by the test device is at the maximum value by adjusting the position of the device under test.

Wherein, the accompanying testing device may be a smart phone, a tablet computer or a notebook computer and the like. The test equipment may be a spectrum analyzer or any other instrument capable of studying the spectrum structure of an electrical signal, which is not limited here. In the accompanying drawings of this embodiment, the device to be tested is a wireless router, the companion device to be tested is a notebook computer, and the test device is a spectrum analyzer as an example.

In an exemplary embodiment, the position of the device to be tested and the orientation of the antenna in the device to be tested can be adjusted at each position, so as to determine that the test device receives Each signal power value, and then determine the location of the device under test when the signal power received by the test device is the maximum value, as the target location of the device under test.

For example, assume that the location of the device under test includes three locations A, B, and C, and the antenna in the device under test includes three orientations of 1, 2, and 3. Then, by making the device under test respectively located at positions A, B, and C, and adjusting the orientation of the antenna in the device under test at each position, it can be determined that when the device under test is located at position A and the antenna is facing 1, 2, and 3 respectively, the When the device under test is located at position B and the antennas are facing 1, 2 and 3 respectively, and when the device under test is located at position C and the antennas are facing 1, 2 and 3 respectively, the power values of the signals received by the test device. If the device under test is at position A and the antenna is facing 2, and the signal power value received by the test device is the largest, then it can be determined that the target position of the device under test is position A.

It should be noted that, in the embodiment of the present application, the position of the device under test is adjusted to determine the target position of the device under test when the signal power received by the test device is at the maximum value. The data transmission speed between meets the following conditions: the data transmission speed between the device under test and the accompanying device is the data transmission speed of the device under test at the maximum transmission power.

Correspondingly, before step 101, it may also include:

Obtain the maximum transmit power of the device under test and the corresponding target rate mode;

Control the accompanying device under test and the device under test, and perform data transmission in the target rate mode.

Wherein, the target rate mode includes parameters such as the data transmission rate of the device under test.

Specifically, the RF circuit of the device under test can be directly installed in the RF test socket, and the maximum transmit power of the device under test can be obtained by testing the transmit power of the RF test socket, and the maximum transmit power of the device under test can be recorded. The data transmission speed of the device can control the accompanying device under test and the device under test in the measurement scene shown in Figure 2, and perform data transmission at the data transmission speed corresponding to the maximum transmission power of the device under test.

Step 102, detecting the output power value of the signal transmitter when the signal power received by the test equipment reaches the maximum value, wherein the signal transmitter is used to drive the omnidirectional antenna located at the target position.

Specifically, after determining the target position of the device under test when the signal power received by the test device is the maximum value, the device under test can be replaced with an omnidirectional antenna, that is, as shown in Figure 3, the wireless antenna shown in Figure 2 The DUT is replaced by an omnidirectional antenna, and the omnidirectional antenna is located at the target position of the device under test determined in step 101, and the omnidirectional antenna is connected to an external signal transmitter at the same time, and the signal transmitted by the signal transmitter passes through the omnidirectional antenna. Test equipment receiving antenna reception. Then, by adjusting the output power of the signal transmitter, the signal power received by the test equipment is changed accordingly, so that when the signal power received by the test equipment reaches the maximum value, the output power value of the signal transmitter is detected.

Wherein, the maximum value of the signal power received by the test device refers to the maximum value of the signal power received by the corresponding test device when the device under test is at the target position in step 101 .

Step 103: Determine the actual equivalent isotropic radiated power of the device under test according to the output power value of the signal transmitter and the gain value of the omnidirectional antenna.

Wherein, the gain value of the omnidirectional antenna may be determined according to characteristics such as size and shape of the omnidirectional antenna.

In an exemplary embodiment, after determining the output power value of the signal transmitter, the actual equivalent isotropic radiated power of the device under test can be determined by the following formula (1):

EIRP＝P+G (1)

Among them, EIRP is the actual equivalent isotropic radiated power of the device under test, P is the output power value of the signal transmitter, and G is the gain value of the omnidirectional antenna.

It can be understood that, through the measurement scenario shown in FIG. 3 , when determining the output power value of the signal transmitter, the signal transmitter and the omnidirectional antenna may be connected through a radio frequency coaxial cable. The radio frequency coaxial cable may have a loss value. When the loss value of the radio frequency coaxial cable is small, the loss value of the radio frequency coaxial cable can be ignored as described in the foregoing embodiment, and only the output power of the signal transmitter value and the gain value of the omnidirectional antenna to determine the actual equivalent isotropic radiated power of the device under test. When the loss value of the RF coaxial cable is large, in order to make the result of the actual equivalent isotropic radiated power of the device under test more accurate, it is also necessary to consider when determining the actual equivalent isotropic radiated power of the device under test Loss values for RF coaxial cables.

That is, before step 103, it may also include:

Correspondingly, step 103 may specifically be implemented in the following manner:

According to the output power value of the signal transmitter, the gain value of the omnidirectional antenna and the loss value of the RF coaxial cable, determine the actual equivalent omnidirectional radiation power of the device under test.

In an exemplary embodiment, the actual equivalent isotropic radiated power of the device under test can be determined by the following formula (2):

EIRP＝P+G-loss (2)

Among them, EIRP is the actual equivalent isotropic radiated power of the device under test, P is the output power value of the signal transmitter, G is the gain value of the omnidirectional antenna, and loss is the loss value of the RF coaxial cable.

It should be noted that, due to the complex electromagnetic environment in practical applications, there are a large number of unstable wireless electromagnetic wave interferences, which may affect the entire measurement efficiency and measurement results. Therefore, in order to avoid the interference of wireless electromagnetic waves, when measuring the equivalent isotropic radiated power of equipment in this embodiment, as shown in Figure 2, the receiving antennas of the equipment under test, accompanying equipment under test and testing equipment can be placed in a shielding environment , and as shown in Figure 3, place the omnidirectional antenna and the receiving antenna of the test equipment in a shielded environment to ensure the stability and reliability of the measurement results.

Further, after determining the actual equivalent isotropic radiation power of the equipment to be tested, the actual equivalent isotropic radiation power of the equipment to be tested can be compared with the limit value specified by the regulations to determine the equivalent isotropic radiation power of the equipment to be tested. Check whether the actual equivalent isotropic radiated power of the test equipment exceeds the regulatory limit. For example, after determining the actual equivalent isotropic radiated power of the device under test, it can be judged whether the actual equivalent isotropic radiated power of the device under test exceeds the European Conformity (conformity of European, referred to as CE) or the US Federal Communications Commission (Federal Communications Commission). Commission, referred to as FCC) limits. If the actual equivalent isotropic radiated power of the device under test is greater than the equivalent isotropic radiated power specified by regulations, it is necessary to adjust the shape of the antenna in the device under test or the impedance in the radio frequency circuit until the actual equivalent isotropic radiated power of the device under test The radiated power is less than the equivalent isotropic radiated power defined by regulations.

It can be understood that the equipment equivalent omnidirectional radiated power measurement method provided in the embodiment of the present application determines the maximum value of the signal power received by the test equipment under the actual working condition of the equipment under test, and then uses the omnidirectional antenna plus the signal transmitter. The method simulates the transmission power of the equipment under test under actual working conditions, and the signal transmitted by the signal transmitter is received by the receiving antenna of the test equipment after passing through the omnidirectional antenna. The signal power received in the way of antenna plus signal transmitter is the same as the maximum signal power received by the test equipment under actual working conditions, and then according to the output power value of the signal transmitter and the gain value of the omnidirectional antenna , the EIRP value of the device under test can be obtained under actual work, and then it can be judged whether the EIRP value of the device under test exceeds the legal limit.

The above method of measuring EIRP uses an omnidirectional antenna plus a signal transmitter to simulate the transmission power of the device under test under actual working conditions, so the measured EIRP is the EIRP value of the device under test under actual work. There is no error in the result of the EIRP value measured by the above method, which is consistent with the actual measurement result, so it is more accurate and reliable.

In the method for measuring the equivalent isotropic radiated power of equipment provided in the embodiments of the present application, the position of the equipment under test is first adjusted to determine the target position of the equipment under test when the signal power received by the equipment under test is at the maximum value, and then the equipment under test is placed Replace it with an omnidirectional antenna, and make the omnidirectional antenna at the target position, and then detect the output power value of the signal transmitter driving the omnidirectional antenna when the signal power received by the test equipment reaches the maximum value, and finally according to the output power value of the signal transmitter and the gain value of the omnidirectional antenna to determine the actual equivalent isotropic radiated power of the device under test. Thus, the measurement of the equivalent isotropic radiated power of the device to be tested is realized, and there is no error in the measurement result, which is consistent with the actual measurement result, and the accuracy and reliability of the measurement result are improved.

From the above analysis, it can be known that the equipment equivalent omnidirectional radiated power measurement method provided by the embodiment of the present application can use an omnidirectional antenna plus a signal transmitter to simulate the transmission power of the equipment under test under actual working conditions, and then realize the measurement of the equipment under test. Accurate measurement of equivalent isotropic radiated power. Further, the equipment equivalent omnidirectional radiated power measurement method provided by the embodiment of the present application can also determine whether the impedance of the radio frequency circuit of the device under test matches the impedance of the antenna. The following describes the equipment provided by the embodiment of the present application in conjunction with Figure 4 The measurement method of effective omnidirectional radiated power will be further explained.

Step 203, adjust the position of the device under test to determine the target position of the device under test when the signal power received by the test device is at a maximum value.

Step 204 , detecting the output power value of the signal transmitter when the signal power received by the test equipment reaches the maximum value, wherein the signal transmitter is used to drive the omnidirectional antenna located at the target position.

Step 205, acquiring the loss value of the radio frequency coaxial cable.

Step 206: Determine the actual equivalent isotropic radiated power of the device under test according to the output power value of the signal transmitter, the gain value of the omnidirectional antenna, and the loss value of the radio frequency coaxial cable.

Wherein, for the specific implementation process and principles of the above steps 201-206, reference may be made to the detailed description of the above embodiments, and details will not be repeated here.

Step 207: Determine the reference equivalent isotropic radiated power of the device under test according to the maximum transmission power of the device under test and the gain value of the antenna in the device under test.

Specifically, the radio frequency circuit of the device under test can be directly installed in the radio frequency test socket, and the maximum transmit power of the device under test can be obtained by testing the transmit power of the radio frequency test seat. In addition, the nominal value of the antenna gain in the antenna specification of the device under test can be used as the gain value of the antenna in the device under test.

In an exemplary embodiment, the reference equivalent isotropic radiated power of the device under test can be determined by the following formula (3):

EIRP'=P'+G' (3)

Among them, EIRP' is the reference equivalent isotropic radiated power of the device under test, P' is the maximum transmit power of the device under test, and G' is the gain value of the antenna in the device under test.

It can be understood that in practical applications, there is usually a feeder loss between the transmitter of the equipment under test and the antenna feed. When the feeder loss is small, the feeder loss can be ignored as shown in formula (3), and only based on the Determine the reference equivalent isotropic radiated power of the device under test based on the maximum transmit power of the device under test and the gain value of the antenna in the device under test. When the feeder loss value is large, in order to make the result of the reference equivalent isotropic radiated power of the device under test more accurate, it is also necessary to consider the loss value of the feeder when determining the reference equivalent isotropic radiated power of the device under test.

That is, before step 207, it may also include:

Obtain the feeder loss between the output terminal of the device under test and the antenna feed;

Correspondingly, step 207 can be implemented in the following manner:

According to the maximum transmission power of the device under test, the gain value of the antenna in the device under test and the feeder loss between the output end of the transmitter of the device under test and the antenna feed source, determine the reference equivalent omnidirectional radiated power of the device under test.

In an exemplary embodiment, the reference equivalent isotropic radiated power of the device under test can be determined by the following formula (4):

EIRP'=P'+G'-loss' (4)

Among them, EIRP' is the reference equivalent isotropic radiated power of the device under test, P' is the maximum transmit power of the device under test, G' is the gain value of the antenna in the device under test, and loss' is the output of the transmitter of the device under test The feedline loss between the terminal and the antenna feed.

Step 208 , judging whether the difference between the actual equivalent isotropic radiated power and the reference equivalent isotropic radiated power is within a preset range, if yes, execute step 209 , otherwise, execute step 210 .

Step 210, adjust the shape of the antenna in the device under test, and/or adjust the impedance in the radio frequency circuit, and return to step 201 until the difference between the measured actual equivalent isotropic radiated power and the reference equivalent isotropic radiated power The value is within the preset range.

Specifically, a range can be set in advance. After determining the actual equivalent isotropic radiation power and the reference equivalent isotropic radiation power of the equipment to be tested, the actual equivalent isotropic radiation power and the reference equivalent isotropic radiation power Poor power. If the difference between the actual equivalent isotropic radiated power and the reference equivalent isotropic radiated power is within a preset range, it can be determined that the impedance of the radio frequency circuit of the device under test matches the impedance of the antenna.

If the difference between the actual equivalent isotropic radiated power and the reference equivalent isotropic radiated power is not within the preset range, it can be determined that the impedance of the radio frequency circuit of the device under test does not match the impedance of the antenna. At this time, you can adjust the shape of the antenna in the device under test or adjust the impedance of the RF circuit in the device under test, or adjust the shape of the antenna in the device under test and the impedance in the RF circuit at the same time, and then re-determine the actual equivalent of the device under test The isotropic radiated power and the reference equivalent isotropic radiated power until the measured actual equivalent isotropic radiated power and the difference between the reference equivalent isotropic radiated power are within a preset range.

Wherein, the preset range can be arbitrarily determined according to needs, for example, the preset range can be set to be less than 3 decibels (dB). The form of the antenna may include the shape and size of the antenna.

In an exemplary embodiment, the impedance in the radio frequency circuit can be adjusted by adjusting parameters such as capacitance or inductance in the radio frequency circuit.

It should be noted that by adjusting the shape of the antenna in the device under test or adjusting the impedance of the RF circuit in the device under test, or adjusting the shape of the antenna in the device under test and the impedance of the RF circuit at the same time, until the measured actual equivalent full After the difference between the reference equivalent isotropic radiated power and the reference equivalent isotropic radiated power is within the preset range, the last determined actual equivalent isotropic radiated power of the device under test can be used as the final effective equivalent isotropic radiated power of the device under test. to radiate power.

Through the above process, the impedance in the RF circuit of the device under test can be guaranteed to match the impedance of the antenna, thereby avoiding the wireless performance of the device under test when the impedance in the RF circuit of the device under test is seriously mismatched with the impedance of the antenna. , to improve the wireless performance of the device under test.

In addition, in the embodiment of the present application, the orientation of the antenna in the device under test may also be determined when the device under test is configured.

Specifically, in the process of measuring the actual equivalent isotropic radiated power of the device under test, the location of the device under test and the orientation of the antenna in the device under test can be adjusted at each position to determine the When the positions of the antennas are facing different directions, the power values of the signals received by the test equipment are tested. Therefore, when the impedance of the RF circuit of the device under test is matched with the impedance of the antenna, during the corresponding measurement process, when the signal power received by the test device is at the maximum value, the orientation of the antenna in the device under test is determined as when the device under test is configured The final orientation of the antenna in the DUT.

That is, the device equivalent isotropic radiated power measurement method provided in the embodiment of the present application may also include:

At each position, adjust the orientation of the antenna in the device under test to determine the target orientation of the antenna in the device under test when the signal power received by the test device is at its maximum value;

After determining the actual equivalent isotropic radiated power of the device under test and the reference equivalent isotropic radiated power, if it is determined that the impedance of the RF circuit of the device under test matches the impedance of the antenna, the recorded The target orientation is determined as the orientation of the antenna in the DUT when the DUT is configured. If it is determined that the impedance of the RF circuit of the device under test does not match the impedance of the antenna, adjust the shape of the antenna in the device under test, or the impedance in the RF circuit, or the shape of the antenna in the device under test and the impedance in the RF circuit, Until the difference between the measured actual equivalent isotropic radiated power and the reference equivalent isotropic radiated power is within the preset range, the last recorded target orientation of the antenna in the device under test can be determined as the configuration to be tested device, the orientation of the antenna in the device under test.
