-For component evaluation and performance purposes, as opposed to quick prototyping, the user is directed to Analog Devices [[/resources/eval/sdp|System Demonstration Platform]] (**SDP**). The **SDP** consists of a: +{{page>common_sdp}}
-  * a controller board, like the **[[resources/eval/sdp/sdp-b|EVAL-SDP-CB1Z]] (SDP-B)** +
-  * a compatible Analog Devices SDP [[adi>sdp#exallist|product evaluation board]] +
-  * corresponding PC software +
-The EVAL-SDP-CB1Z controller board is part of Analog Devices SDP providing USB 2.0 high-speed connectivity to a PC computer running specific component evaluation software.  Each SDP evaluation daughter board includes the necessary installation files needed for this performance testing. It's expected that the analog performance on the two platforms may differ.+

 The [[adi>AD7983]] is a 16-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD. It contains a low power, high speed, 16-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, it samples an analog input IN+ between 0 V to REF with respect to a ground sense IN−. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput. The [[adi>AD7983]] is a 16-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD.

-The EVAL-AD7983SDZ evaluation board is a member of a growing number of boards available for the SDP. It was designed to help customers evaluate performance or quickly prototype new AD7983 circuits and reduce design time. When using this evaluation board with the SDP board or BeMicro SDK board, apply +7.5V as +Vs, a voltage between -2V and -5V as -Vs and +2.5V as VDD.+The EVAL-AD7983SDZ evaluation board is a member of a growing number of boards available for the SDP.

-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 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.+At this point everything is set up and it is possible to start the evaluation of the ADI hardware.
