IWR1843: High accuracy level sensing not work when exceed 512 samples

Hi,

I have ported high accuracy level sensing lab from IWR1642 to IWR1843. And using High_Accuracy_Visualizer to check the result. It works fine with the default chirp config which is provided from the mmwave_industrial_toolbox_4_2_0. 

Then I try to modified the chirp config: increase the sample rate and increase the sample number, so the overall sample time is nearly same as the default config. After I changed the config, I find the High_Accuracy_Visualizer could not display the range profile oproperly any more. and also no valid object detection as well.. below is the chirp config I used.  Any ldea what cause this problem?

Thanks and Best Regards

Dong
