IWR6843ISK: Inquiry about the Meaning of adcFmt = 0 (Complex Format) in mmWave SDK

Part Number: IWR6843ISK

Tool/software:

Hello,

I’m currently working with TI's mmWave SDK version 03_05_00_04.

In the file mmwdemo_adcconfig.h located at
C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\utils,
the structure MmwDemo_ADCBufCfg_t defines adcFmt, where:

adcFmt = 0 is labeled as Complex

adcFmt = 1 is labeled as Real

However, there is no clear documentation specifying whether the "Complex" setting corresponds to Complex 1x or Complex 2x format.

Could you please clarify which format is intended by adcFmt = 0?
If there is an official reference or documentation that defines this, I would greatly appreciate it.

Thank you.
