DCA1000EVM: Relationship Between ADC Bits and Q Format & How to Retrieve Their Values

Tool/software:

Hi,

I have two questions regarding data acquisition and processing with the AWR1243:

  1. Is there a relationship between ADC Bits and Q Format?
    In different post-processing modes of Radar Studio (Complex 1x, Complex 2x, Real mode), does the ADC sampling bit-width (ADC Bits) affect the Q Format of IQ data? If so, how are they related?

  2. How can I find the values of ADC Bits or Q Format?
    Where can I check the specific values of ADC Bits and Q Format in Radar Studio or SDK configurations? Can these parameters be retrieved via an API, or is there a standard method to determine them?

Thanks in advance for your help!
