Further, in this embodiment, the setting method applicable to the verification system 10 and the computer system 12 can be further summarized into a compensation process 20. As shown in FIG. 2, the compensation process 20 is compiled into a code and stored in the storage. In the device 122, the operation between the verification system 10 and the computer system 12 is adaptively controlled, and is not intended to limit the scope of the present invention. The compensation process 20 includes the following steps:

Step 200: Start.

Step 202: Acquire an overall attenuation value of one of the noise generators 100.

Step 204: Acquire a plurality of respective attenuation values corresponding to the transmission ports Port1~PortN.

Step 206: Compare the difference value between the respective attenuation values of each transmission chirp and the overall attenuation value to compensate for the plurality of respective attenuation values corresponding to the transmission ports Port1~PortN, and correspondingly obtain the complex number of the transmission ports Port1~PortN. The downlink power value.

Step 208: End.

In step 202, the user obtains the overall attenuation value of the noise generator 100 through the computer system 12, that is, the noise generator 100 adjusts the initial noise signal of the output according to the product specifications of the network bridge 102. The size corresponds to providing different sizes of noise initial signals to the network bridge 102. In this embodiment, the noise generator 100 can adaptively adjust the magnitude of the overall attenuation value according to the control of another code to generate different noise initial signals, which is not intended to limit the scope of the present invention.

In step 204, the user obtains the plurality of downlink powers corresponding to the transmissions of the network bridge 102, Port1~PortN, through the spectrum analyzer 104, and obtains the transmission. 复Port1~PortN multiple individual attenuation values. In detail, in this embodiment, the user connects the spectrum analyzer 104 and the transmission ports Port1~PortN respectively to measure the initial downlink power values of different transmission ports, and accordingly, the user can further refer to the computer system 12 according to the computer system 12 A downlink power value lookup table preset in the medium compares the initial downlink power values of different transmission ports with their corresponding values in the downlink power value lookup table, and further obtains respective attenuation values of different transmission ports. At the same time, the noise generator 100 can also operate at different operating frequencies, so that the spectrum analyzer 104 can obtain the respective attenuation values of different transmissions at different operating frequencies by repeating the operation of step 204.

In step 206, the computer system 12 compares the difference value between the respective attenuation values of each transmission port and the overall attenuation value to compensate for the plurality of respective attenuation values corresponding to the transmission ports Port1~PortN, and obtains the corresponding transmission values.

For example, in this embodiment, the computer system 12 will first obtain the overall attenuation value of the noise generator 100 as 40 steps, wherein each step corresponds to 0.25 dB. Then, the computer system 12 obtains the respective attenuation values of different transmissions at different operating frequencies, and then compares the difference between the respective individual attenuation values of the transmission ports Port1~Port16 and the overall attenuation value, for example, the transmission port 11 is analyzed by the spectrum analyzer. After 104 measurements, the row power value is 42 steps. In this case, the processor 120 can determine that the difference between the overall attenuation value (ie, 40 steps) and the line power value under the transmission port (ie, 42 steps) is 2 steps, and is further determined by the computer system 12. The difference value (ie 2 steps) corresponds to the row power value under the modified transmission port1, for example, another step value is converted to 0.5 steps (ie 2×0.25 dB), and then the initial downlink power value of the port 1 Port1 is transmitted. With 0.5dB, a new downlink power value for different transmissions can be obtained.

It should be noted that the storage device 122 of the computer system 12 of the embodiment further stores a preset threshold value, so that the computer system 12 obtains a new downlink power value under different operating frequencies, and then corresponds to a new downlink. The difference between the power value and the preset threshold value is such that the new downlink power value does not exceed the preset threshold value, that is, the preset threshold value includes an upper/lower limit threshold value, and the computer system 12 will cause the new downlink power value not to exceed the upper limit value. Threshold value or lower limit threshold.

In this embodiment, if the new downlink power value does not exceed the preset threshold, the storage device 122 of the computer system 12 will store a new downlink power value, thereby forming another lookup table (or replacing the original downlink power value). Lookup table) for the user to know the plurality of new downlink power values that are transmitted at different operating frequencies. On the other hand, if the new downlink power value has exceeded the preset threshold, the computer system 12 or the compensation process 20 will determine that the current operation of the transmission is an error compensation operation, and then discard the new downlink power value of the transmission. In this case, the computer system 12 can generate a prompt signal to inform the user, so that the user can appropriately decide whether to re-compensate the transmission, or modify the setting between the verification system 10 and the computer system 12. The constants are not intended to limit the scope of the invention.

It should be noted that a person skilled in the art can also provide a user interface in the computer system 12, correspondingly providing a user to perform a compensation operation between different transmissions, or when generating a fault compensation operation in a single transmission. Corresponding to the relevant setting constant used to modify the transmission port. Of course, the computer system 12 can also set an initialization operation to match the compensation flow. The operation of the process 20 enables the computer system 12 to be coupled to the verification system 10 for the first time, and correspondingly select one of the plurality of downlink power value lookup tables in the storage device 122 and the relevant setting parameters of the verification system 10. In addition, the computer system 12 can also be combined with different switching mechanisms to perform the compensation operation between the plurality of verification systems 10 at the same time, which is also the scope of the present invention.
