And stored in the storage device 122 to appropriately control the operation between the verification system 10 and the computer system 12, but is not intended to limit the scope of the present invention. The compensation process 20 includes the following steps:

Step 200: Start.

Step 202: Obtain a power lookup table corresponding to the transmission port 1 Port1~PortN of the network bridge 102.

Step 204: Connect the device under test 104 to one of the ports 1Port1~PortN.
