LAUNCHXL-CC26X2R1: IQ data question.

Nick Sun

Part Number: LAUNCHXL-CC26X2R1

Hi team,

Here's the request from the customer:

SDK is 5.20, using the two antennas of antenna 1 and antenna 2 to switch and getting the IQ data in the figure below:

A pkt has 180 sampling data, do these 180 sampling data include the IQ data of antenna 1 and antenna 2?
How to distinguish between the IQ data collected by Antenna 1 and Antenna 2?

Could you help check this case? Thanks.

Best Regards,

Nick

Hi Clément，

Here's reply from customer:

Using sdk5.30, the configuration shown in Figure 1 is switched between Antenna 1 and Antenna 2.

The IQ data collected through the official Python script is shown in Figure 2. There are multiple pkt channels in the obtained data.

The question is which of the following is the IQ data obtained through the official Python script?

IQ data collected within the same pkt channel is for Antenna 1 only or for Antenna 2 only?
The IQ data in the same pkt contains both antenna 1 and antenna 2 acquired data?

Best Regards,

Nick
