Hello
We are right now in the certification of our CC3200 cevice and the EN300 328 V2.1.1 adaptivity test failed. Adding the interference signal the EUT doesn't stop trasmissions.
I found on page 12-13 and 50 of this PDF this test but there it was PASS:
Is there something that we have to enable so the CC3200 passes this test?
Happy for any hints!
Thank you
Hello Riz
The certification lab confirmed us that they are not using the radio tool. The RF cable is soldered right after the balun (on the antenna side) and the antenna trace is cut.
They just confirmed us that the test is still failing. What else could be wrong??
They wrote to us:
"We have re-test it but still failed, it does not stop the transmission when inject interference signal. It will delay after a period of time to stop transmission.
T1 is inject interference signal, the standard require this time after the EUT will to stop the transmission But this sample still transmission until T2 stop.
In addition, we have tried to increase the interference signal level by 7dBm, but the result is the same I suggest you can verification it at local"
Here a pic of the RF cable after the balun:
Calibration AWGN signal from the certification lab:
And the measurement again as they described it above:
Hello Riz
Thanks for your reply.
Next step is that we'll try with a new setup.
Here is the block diagram:
For the series firmware, I'm not sure where this feature handled exactly?
Is it handled in the WiFi-Network processor by the servicepack (provided by TI) or in the application firmware?
thanks

Hello Roland,
thank you for the feedback that the issue is solved.

Hello Roland,
I'm also having this same problem regarding the adaptivity test.
You mention that test mode wasn't on for the test. How did you activate it?
Is it some configuration that you have to do?
It would help a lot if you would provide me an answer.
Thank you very much for your attention!
