CC2640R2F: CC2640R2F: I/Q samples - Antenna Pattern

Part Number: CC2640R2F

Hello,

From my understanding, I know that we have 512 samples in a packet. (32*16( number of samples per block ) = 512) and antenna 2 from antenna Array 1 ( A1.2 ) is the initial antenna which detects and receives Incoming packets at the beginning and at the end of data collection.

What I want to know about the pattern below is the following;

1. How do we know the exact antenna pattern in the I/Q raw data samples that are exported to a csv file. Is it 16 samples from A1.2 and then A1.1 A1.2 A1.3 and so on or?

2. We should calculate the Phase difference by finding the difference between the vector angle from the I/Q samples of the toggling antennas ?

3. Should we only consider samples from [8-15] of each antenna ( A1.1 A1.2 A1.3 .. A1.1 .. ) because samples from [0-7] are measurement Errors and therefore we will have 256 valid samples to work with in a           single packet?

I would very much appreciate it if you could clarify my questions.

Thank you in Advance.

Best regards,

Fatma
