AWR1843: Which value can I use as ADC sampling rate?

Nobu

Part Number: AWR1843

Hello.

I have used profileCfg below and I want to halve maximum range and number of sample.

profileCfg 0 77 7 7 58 0 0 68 1 128 2750 0 0 30

I tried to use profileCfg below, but this command couldn't be used.

profileCfg 0 77 7 7 58 0 0 68 1 64 1375 0 0 30

I think number of sample "64" is no problem, so error point is ADC sample rate "1375".

In user guide, sample rate is "any value as per mmwavelink doxgen/device datasheet".

I checked "C:\ti\mmwave_sdk_03_01_01_02\packages\ti\demo\xwr18xx\mmw\docs\doxygen\html\index.html" and other pages,
but I can't find the information I want.

How can I know valid ADC sample rate?

Hello Nobu-San,

Please refer to the mmWave ICD i.e. the Interface control Document to see the configurable values for ADC Sampling rate. You will find this information in the following API: "AWR_PROFILE_CONF_SB"

mmWave ICD is a part of mmWave DFP package<ver>/docs folder.

Regards,

Ishita
