Hello:
The customer has encountered an issue with DLPA2010 interfering with RF GSM sensitivity. Please help to determine the next steps for analysis and resolution.
Problem phenomenon: When the projection is turned on, the sensitivity of the GSM full channel decreases by more than 10dB, and the GPS CN0 decreases by more than 10dB.
The following experiments have been conducted:
1. Turn off the fan -->No use
2. Turn off the projection light -->No use
3. Paste conductive cloth at the opening of the shielding cover, seal it ->no use
4. Strengthen the grounding of the projection module and wrap it with conductive cloth -->No use
5. Closing FPGA -->No use
6. Close DLPA2005-->interference disappears
