IWR6843ISK-ODS: Question about valid values of Number-Of-ADC-Samples

Part Number: IWR6843ISK-ODS

Tool/software:

Hello,

I attempted to create a 25 cm range resolution as below profile. My script shows the range resolution is 25 cm but demo visualizer indicates 19 cm. Later I figured it out that the Out of box algorithm appeared to take 128 as the number of ADC samples instead of 100 in range resolution calculation. Does the number of ADC samples have to the power of 2? I didn't see any statement about that in my impression. Please tell me which specification if I missed out somehow.

profileCfg 0 60.00 7 3 44.79 0 0 23.98 1 100 4000 0 0 158

Thanks.
