======EVALUATING THE AD9736/AD9735/AD9734 DIGITAL-TO-ANALOG CONVERTER======

=====Preface=====
This user guide describes both the hardware and software setup needed to acquire data capture from [[adi>eval-ad9736|AD9736-DPG2-EBZ]] evaluation board to characterize [[adi>AD9736]] 14-bit 1200 MSPS  digital-to-analog converter.

This guide shows how AD9736-DPG2-EBZ works with SDP-H1 or ADS7-V2 controller board developed by Analog Devices. Documentation and software updates for using the <fc #ff0000>[[adi>AD9734]]/[[adi>AD9735]]/[[adi>AD9736]]</fc> Evaluation Boards are included in a self-extracting update file. Documentation can also be downloaded individually below.

    * USB-A to USB-Mini Cable
  * The following are included in ADS7-V2 Evaluation Kit:
    * 12V 60W AC/DC Power Supply
    * Power Cord
    * USB-A to USB-B Cable

=====Quick Start Guide=====
  - Attach the evaluation board to the FMC connector of SDP-H1 or ADS7-V2 using the AD-DAC-FMC-ADP adapter board. Connect continuous wave generator for clock input to J1, and the DAC output from J2 to a signal/spectrum analyzer. Connect the evaluation board to PC via USB and to a 5Vdc 2A power supply via banana plug cables. Refer to Figures 1a and 1b.Set clock input to **500 MHz and 6 dBm**.
     * If using **SDP-H1**,  Connect to PC via USB and to a 12Vdc wall wart.
     * If using **ADS7-V2**, Connect to PC via USB and to a 12V 60W AC/DC power supply. Switch the board ON using S1 beside the connector for 12V supply.
  - Open ACE. The board will automatically be recognized by the software. Otherwise, install the plugin for AD9736 evaluation board. Apply the configuration wizard settings shown in Figure 2. <WRAP centeralign>{{ :resources:eval:dpg:ad9736_ace_chip_view.png?direct&600 |}}//Figure 2. ACE Chip View Initial Configuration Wizard//</WRAP>
  - Start DPG Lite or DPG Downloader. At the SDP-H1 or ADS7-V2 settings, ensure that **Evaluation board** is equal to AD9736 and DCO frequency of around 250 MHz should be displayed.
  - In DPG Lite or DPG Downloader, from the **Add Generator Waveforms** pulldown menu, select **Single Tone** and apply the settings as shown in Figures 3a and 3b.Set **Data Rate** to 500 MHz and **Desired Frequency** to 50 MHz.
  - Continuing on setting up DPG Lite or DPG Downloader, set **DAC resolution** to 14 bits.\\ <WRAP centeralign>{{ :resources:eval:dpg:ad9736_dpglite_sdp-h1.png?nolink&600 |}}//Figure 3a.

  - Select the Single tone from the **Data Vector** pulldown menu
  - Press the download arrow and then the play button. The FFT plots similar to Figures 4 should appear in the signal/spectrum analyzer.\\ <WRAP centeralign>{{ :resources:eval:dpg:ad9736_output_fft.png?nolink&600 |}}//Figure 4. EVAL-AD9736 FFT for Data Rate = 500 MHz, Fout = 50 MHz//</WRAP>

=====Troubleshooting=====
This section lists items to check and practices to use when debugging any unexpected performance of a board. If unexpected results occur:
  * Check the supply voltage of the evaluation board. Voltage rail should be 3.3V.
  * Check if all (3) blue LEDs on the AD-DAC-FMC-ADP board is lit up. Reconnect the board to the FMC connector of SDP-H1 if not lit up.
  * Check if the SDP-H1 is being supplied properly by 12Vdc adaptor. Some LEDs on the SDP-H1 should lit up.
  * Power cycle both the SDP-H1/ADS7-V2 and the AD9736 evaluation board.
  * Check on the Spectrum Analyzer if the DAC clock inputs are properly driven. For 500MHz clock, the spectrum analyzer should detect a weak signal at 500MHz. If not detected, check properly the clock source and connections.
  * Disconnect and reconnect the SDP-H1 /ADS7-V2 and AD9736 evaluation board. Reopen DPG Lite software.
