AWR1642: ADC data format using AWR1642+DevPack+TSW1400

Omin Chou

Part Number: AWR1642

Hi all,

I want to clarify more about ADC data format when use AWR162+DevPack+TSW1400.

When default RadarStudio configures 16 bit complex the order of data should be:

RX1-I sample 0 , RX1-Q sample 0 , RX1-I sample 1 , RX1-Q sample 1 .....Rx1-I sample N-1 , RX1-Q sample N-1 , RX2-I sample 0 , RX2-Q sample 0 ……

Questions:

1. The above data order is correct or not.

2. Is there any header between frames?

3. What is the first sample as following figure? Does they align with big-endian or little-endian?

Thanks in advance.

Hello Omin Chou,
I wanted to confirm if you are looking at the data file captured by TSW in binary format, it that right?

Hi Vivek,

Thanks for your reply.
Yes, the default file name is adc_data.bin.

Hello Omin Chou,
Thank you for the confirmation.
1) You are right , the data format is as you have listed. Each value (say Rx1_I0) is a 16bit value .
2) There is no header for the frame by default. You can write your own application that can append headers if required. The AWR1642 SDK capture application provides an example code to add your own header values.
3) The 16 bits are MSB-LSB as is.

Regards,
Vivek
