LAUNCHXL-CC26X2R1: Some issues about IQ data.

Part Number: LAUNCHXL-CC26X2R1

i team,

Here's the request from the 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?

  1. IQ data collected within the same pkt channel is for Antenna 1 only or for Antenna 2 only?
  2. The IQ data in the same pkt contains both antenna 1 and antenna 2 acquired data?
  3. The figure below is the image of the data that customer obtained after separating the I data of antenna 1 and 2 in the order of antenna 1 and 2 acquisition. Above is the I data for Antenna 1 and below is the I data for Antenna 2.I data from antenna 1 can be found not to look like a sine wave at all, is this normal?
  4. The picture below is a pkt channel to collect 180 sets of I data, this 180 sets of data does not separate the antenna 1, 2 data, instead the I data image is more like a sine wave, why?

Could you help check this case? Thanks.

Best Regards,
