Embodiment 2
[0030] Embodiment 2: The side length of the hollow metal cavity is a rectangle of 55*50cm, the window is changed to a square hole of 30*30cm, other conditions remain unchanged, and the above steps 1~5 are repeated, it can be found that the test results Not affected by window size.
[0031] The tested fabric material is tightly covered on the window through the flange.
[0032] The transmitting antenna is placed in the reverberation chamber, and its distance from each corner of the reverberation chamber is different, and the direction of the transmitting antenna is the corner closest to it in the reverberation chamber.
[0033] In the step 3, the stepping speeds of the first agitator and the second agitator are consistent.
[0034] This method avoids setting up field strength meters on the inner and outer sides of the cavity, and only needs to set up a field strength meter in the hollow cavity. The test results are not affected by the size of the window. The test equipment is ...
