AFE4300: I have a problem with continuous IQ measurements.

Part Number: AFE4300

Hello.

I have previously asked that there is a problem with continuously IQ measurements.
link : e2e.ti.com/.../881585

The answer was then asked to see the Archiving Deminist phase in IQ Mode section on the datasheet.

I looked it up and read it, but I can't understand it.

Can you explain it in detail?

The picture below shows the results obtained by continuous measurements.

The order is the same as 8 kHz (I,Q) - 16 kHz (I,Q) - 32 kHz (I,Q) - 64 kHz (I,Q) - FWR, programmed to repeat.

At 8 kHz, I and Q values are constant even when measured repeatedly.
However, at other frequencies, the change in Q value was particularly significant.

Help me.
