3.16 DCA1000EVM Mode

The setup for raw data capture using DCA1000EVM is shown in Figure 3-31. For more details on raw ADC data capture, refer to DCA1000 mmWave Studio xWRL6844 section in the following path of Tirex page (mmWave radar sensors/ Embedded software/ Radar Toolbox/ Hardware Docs/ DCA1000 Perdevice/ DCA1000 mmWave Studio xWRL6844 .

Note: When EVM is directly mated with DCA1000 board, kindly use spacers which are included in the kit and ensure no physical contact happens between DCA1000 and the xWRL6844EVM as it can damage the boards.
