-After successfully programming the FPGA, launch the "data_capture.bat" from the "../DataCapture" folder.+At this point everything is set up and it is possible to start the evaluation of the ADI hardware. To capture data from the ADC run the **data_capture.bat** script located in the **"../DataCapture"** folder from the reference design .zip file. Every time the script is run a new batch of 8192 samples are read from the ADC at the ADC's maximum sampling rate and saved into the Acquisition.csv file located in the same folder as the data capture script. On the UART terminal messages will be displayed to show the status of the program running on the FPGA as shown in the picture below.

Line 66: Line 72:
 The reference design is built on a Microblaze based system. It consists of two functional modules, a LVDS interface, and a DMA interface. The LVDS interface captures and buffers data from the ADC. The data is captured using Echoed-Clock mode or Self-Clock mode (depending on the project). The DMA interface then transfers the samples to the external DDR-DRAM. The capture is initiated by the software, and transfered to the PC using a *.tcl script. The reference design is built on a Microblaze based system.
