Provide case details or comments:
To whom it may concern,
we have an appliance using the above mentioned SimpleLink WiFi Chip.
The testing for FCC compliance at the CSA Testlab failed, because the RMS value ist above the limit of 54 dBµV/m.
The test is done using the TI Radio test tool with the settings you see here:
The result of the measurement you see here:
The black line is the RMS value and the limit is exceeded at point M7 and M8.
The design is not so sophisticated, the WiFi chip and a filter band pass, finished:
Can you provide any information what might cause this problem.
For additional information: We did also the testing for the RED (for Europe) at the VDE testlab and hab not problem there.
This is the measurement plot from VDE:
The green line is the RMS value.
Surprising, the line is much lower in this plot, and also we do not see the humps right and left of the 2.4 GHz.
Do you have any idea. If you need more information, please let me know
All pictures you also find attached. Thank you very much.

Another questions:
- Why does the part number selection filed does not recognize the complete part number?
- Why is it not possible to select a different forum before posting the request?
