NTM88 RF output phase noise is high

Please refer to the attachment for specific test waveform. The chip output conduction test is like this, which has nothing to do with antenna matching.  Is there any way to debug？

Hello,

I hope all is great with you.

Yes, it is possible to debug the device. The PTA4 pin places the device in the BACKGROUND DEBUG mode (BDM) to evaluate MCU code and transfer data to/from the internal memory.

You may find further information at the post below:

Codewarrior no debug configuration found?

Please let me know if this information is useful for you.

Regards,

David
