[0027] The product seat 1 has a second rotating motor 13, and the second rotating motor 13 drives a rotating disk 14.

The product carrier 11 is vertically arranged with the rotating disk 14. The product carrier 11 is provided with a suction cup group 12 for adsorbing and fixing the product.

[0028] The following is the working process of the signal interference test device:
[0029] The electronic product is placed on the product carrier 11, and the suction cup group 12 adsorbs the electronic product to fix the electronic product on the product carrier 11.
