Hello,
I am working with the QM33120WDK1 kit and testing PDOA Mode 3.
From the documentation, I understand that in Mode 3 the receiver switches antenna ports in the middle of the STS sequence, resulting in two outputs: STS_POA
and STS2_POA
.
However, based on my own tests, it seems that in PDOA Mode 3 the second half (STS2 / STS2_POA
) is actually being received on Antenna 1.
I was under the impression that by default the first half should correspond to Ant1 and the second half to Ant2, so this result is a bit confusing.
Could you please clarify:
- In the default configuration of QM33120WDK1, which antenna is used for
STS_POA
and which forSTS2_POA
? - Is it expected that
STS2_POA
(STS2) is received on Ant1, or might this be related to configuration or interpretation? - If the default RF port is changed, does the mapping of
STS_POA
andSTS1_POA
swap accordingly?
Any official clarification or reference to register-level documentation for QM33120 would be very helpful.
Thank you!
