IWR6843AOP: how to check reading data is CP,CQ data

HI, 

Please refer to the following e2e thread for additional steps needed to enable CQ data capture.

If you enable CQ data capture correctly, then at the post processing GUI, there is a display option for "CQ metrics - DFE Energy Monitor", you should be able to see the image band and signal band start to make sense to you.   Like image band signal power should be much lower than signal band power.

Hi zigang Yang.

I could not run the RawAdcDataProc_withCQ.m.

I want to know the Settings of mmWaveStudio with which I can run the RawAdcDataProc_withCQ.m.

If you can, I want the lua file of the Setting.

Thanks.

HI, there:

Here attached the LUA script that enables CQ.  You will need to

1) Start radar studio, do connection/firmware loading/RF power up. 

2) Run this script

3) setup DCA1000 and start capture.

Let me know if it works for you.

Best,

Hi zigang Yang.

I could run the RawAdcDataProc_withCQ.m with DataCaptureLoopWithRFInit_CQMode.lua 

Thank you very much.

Now, I am checking that CQ data works nomally.

I measured the FMCW data under the condition that corner reflector is set in front of the antenna (distance is 10cm).

But CQ1 data means no saturation and CQ2 data means no interference.

How can I confirm that CQ data  work normally?

By the way, it is not easy to saturate the front end, because the receive chain has two stages of high-pass filter, which filters the close-in reflection. 

Best,

Zigang
