[0073] In one embodiment, step S5, obtaining the anti-interference test result of the device under test according to the comparison result, includes:
[0074] If the current strength of the interference signal is within the preset signal strength range, the anti-interference test of the device under test is determined to have passed; if the current strength of the interference signal is not within the preset signal strength range, the anti-interference test of the device under test is determined to have failed.
[0075] In an embodiment of the present invention, if the reception quality of the current device under test is affected, that is, the RF reception is interfered, it is determined whether the current strength of the interference signal is within a preset signal strength range. If so, it is considered that the current device under test fails the anti-interference test.
