IWR6843ISK-ODS: Problem with setting the ADC sampling rate in mmWave Studio

Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: DCA1000EVM,

Dear TI Team,

I am working with IWR6843ISK-ODS plus IC Boost and DCA1000EVM to read raw data.

When I am trying to set the ADC sampling rate in mmWave Studio, I received an error message that "The sampling rate is outside the valid range [2, 37.5] Msamp/sec" while I am setting the sampling rate in fact in the valid range.

Also, it seems mmWave Studio does not allow setting a sampling rates above12 Msamp/sec for IWR6843ISK-ODS.

I would be grateful if you let me know how I can fix this issue to have higher ADC sampling rates.

A snapshot of the parameters I set in SensorConfig tab is attached to the message.

Thanks a lot and have a nice weekend.

Best Wishes,

Saeid

HI, Saeid:

The maximum ADC sampling rate is different in different mode and for different device. You can find the detailed limitation at SDK doxygen documentatin:

Best,

Thank you very much Zigang.

It seems the maximum sampling rate of the mmwave radar I am working is 12.5 Msamp/sec. That's why I get an error.

Thank you very much for the reply.

Best Wishes,

Saeid
