IWR6843ISK: the level of the signal changes periodically every 100 frames

Mateusz Mazur
Part Number: IWR6843ISK
I have set IWR6843ISK working with DCA1000 set to 128 chirps/frame (all these same), 2000 frames, every frame has 40ms period
What is observed. The amplitude of signal for first 100 frames is similar ( measured background) for next 100 frames it rises some percents and is stable for these entire 100 frames, next it falls down to previous level observed for first 100 frames, next rises and again and again up and down...
any suggestions?

Hi,

Does this happen regardless of the configuration used? Is this the same issue as linked post?
e2e.ti.com/.../787561

Please try using a different chirp configuration with idle time less than 10usesc, this will prevent the power save and confirm if the issue is caused by the device switching from "low Power" mode

short idle time helps, but it is not a solution when longer idle time is recommended
besides, this effect is only for "even" samples and generally is more noticeable for imaginary part of samples
have You any document with recommendations how to omit such "hazards"

Hi,

The work around is to disable the power save feature or ignore the first chirp. This should also only be seen in the first chirp after "wake up" not in 100 frames.
Can you please confirm that this is the case?

I described case when all chirps in 100 frames have different level comparing to next 100 frames. omitting first chirp is not a solution, as there are 100 frames with chirps per next 100 frames with chirps having different level

Hi,

Please try disabling the power save feature for cases where longer idle time is recommended.
