Hi,
In the datasheet for IWR6843 it seems to be specified what the maximum frequency/us change is (266MHz/us).
I have 3 questions:
1. What would be the slowest we could set it to be?
2. Also are there limitations on frequency bands of use for slow rates? Ive seen in some posts that its best to avoid 62.1 GHz in general. Is that still the case?
3. what documentation and/or tool is best to use to investigate different type of chirp, frequency setups for the IWR6843. thanks.
Hello Dr_SP,
Maximum frequency/us change is 250MHz/us.
Please find my responses to your questions:
1. What would be the slowest we could set it to be?
[Chethan] You could refer to below doxygen from the mmWave SDK, Below are the valid ranges.
D/ti/mmwave_sdk_03_0x_00_0x/packages/ti/control/mmwavelink/docs/doxygen/html/structrl_profile_cfg__t.html
2. Also are there limitations on frequency bands of use for slow rates? Ive seen in some posts that its best to avoid 62.1 GHz in general. Is that still the case?
[Chethan] If you are using narrow bandwidths then there are frequency regions where you would notice doppler spurs on the Range/Doppler heatmaps.
For more information you could refer to below errata:

3. what documentation and/or tool is best to use to investigate different type of chirp, frequency setups for the IWR6843.
[Chethan] There are various tools are available:
