Introduction 

This user guide provides details on how to build and utilize the data acquisition tool 
to capture raw data (ADC samples) from 4x AWR1243 Cascade Radar RF board with 
TDA2x Digital board. 
For 4x AWR1243 Cascade Radar, depending on the Radar configuration, the raw data 
throughput could be up to ~6 Gbps. To save the raw data in real-time to a storage 
device,  it  requires  an  interface  with  very  high  BW  capability.  On  TDA2x,  PCIe 
interface  can  provide  maximum  5Gbps  BW  per  lane  with  total  of  2  lanes.  Using  2-
lane PCIe interface on TDA2x to connect  to a SSD storage device, it is sufficient to 
achieve real-time data acquisition for 4-chip cascade radar use case.
