RFI/De-sense can cause the performance degradation of receiver on wireless products.

The reasons for this degradation are usually the following two:

-RF interference from other working modules (such as camera, display, speaker, SIM/SD card, etc.) in the product with the receiver.

-Interference from other wireless transmitters in the product with the receiver.

RFI/IOP test

-Full-channel fast scanning for the RX sensitivity of Cellular 2/3/4G、BT/WiFi、GPS, etc.

-Failure detection for OTA TIS

Near-field Scanning Test

-Near field scanning for EMI issues in display modules, and assist in assessing the performance

-Near field scanning of both automatic and manual method for PCBA, FPC and cable connection, to identify the noise source and analysis the coupling path
