Dw3000 pdoa and phase

hi,

I get the pdoa info, and aslo want to get the every anttenna phase info, so set the pdoa mode 3, then try to get the Sub-register 0x0C:08 – STS_POA and Sub-register 0x0C:10 — STS1_POA, the two value subtract, compare with the pdoa value, It is found that most of the time the value will vary by about 200. Sometimes the difference is about 2 times.
