After the above work is completed, the mobile drive component 20 drives the fixed frame 30, the micrometer 40 and the flip frame 50 to move a long distance to the set position, and then operates the micrometer 40 to adjust the short distance to move the frame 51 so that it contacts the pressure detection component 90 until the value detected by the pressure detection component 90 reaches the set value. Finally, the electromagnetic wave signal generator 70 emits electromagnetic waves for testing, and the electromagnetic wave signal receiver 80 receives the transmitted electromagnetic wave signal and displays the measured information through the spectrum analyzer 100.

[0028] In one specific embodiment, the mobile drive component 20 of the present application includes a linear groove 21 opened on one side of the test platform 10, a servo screw module 22 arranged in the linear groove 21, linear guide rails 23 respectively arranged on the test platform 10 on both sides of the linear groove 21, and a slide 24 slidingly arranged above the two linear guide rails 23 and connected to the servo screw module 22.
