How to convert the 14 digit POA to the true POA value?

Hi @Wassim_Qorvo ,

Thanks for pointing out the source code. I have a question about interpreting the ipatovPOA value. The comment says it is signed rad*2-12. Does it mean that it is the raw radians value times 2^-12? So to convert it back to radians, I should divide this value by 4096?

However, the ipatovPOA is defined as an uint16_t, which is unsigned. Is this conflicting with the comment? Or should I interpret the ipatovPOA as an int16_t to convert it back to radians?

Secondly, I am curious about the physical meaning of ipatovPOA value. Is it the phase of the CIR value at the first path index (e.g., 740.39)? Then because of existence of the fraction part, this POA value should be more precise compared to directly reading CIR data and calculating the phase myself?

Thanks in advanced!
