=====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 J3, and the DAC output from J1 to a signal/spectrum analyzer. Connect the evaluation board to PC via USB, a 5Vdc 2A power supply to J17. Refer to Figures 1a and 1b.
     * If using **SDP-H1**, set clock input to **300 MHz and 0 dBm**. Connect SDP-H1 to PC via USB and to a 12Vdc wall wart.
     * If using **ADS7-V2**, set the clock input to **2 GHz and 0 dBm**. Connect ADS-V2 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 AD9739 evaluation board. From the AD9739-EBZ tab, Click **“Run Example Startup Routine (Sync Disabled)”**. 
     * If using **SDP-H1**, The MU Controller Locked indicator should light up as shown in figure 2a.
     * If using **ADS7-V2**, The first three indicators should light up as shown in figure 2b. <WRAP centeralign>{{ :resources:eval:dpg:ad9739_ace_boardview.png?nolink&600 |}}//Figure 2a. ACE Initial Board Configuration Wizard for SDP-H1//</WRAP> <WRAP centeralign>{{ :resources:eval:dpg:ad9739_ads7_ace_boardview.png?nolink&600 |}}//Figure 2a. ACE Initial Board Configuration Wizard for ADS7-V2//</WRAP>
  - Double click the AD9739 Box to open chip view. 
     * If using **SDP-H1**, The DLL_LOCKED indicator should light up as shown in figure 3a.
     * If using **ADS7-V2**, All three indicators should light up as shown in figure 3b. <WRAP centeralign>{{ :resources:eval:dpg:ad9739_ace_chipview.png?nolink&600 |}}//Figure 3a. ACE Initial Board Configuration Wizard for SDP-H1//</WRAP> <WRAP centeralign>{{ :resources:eval:dpg:ad9739_adsv7_ace_chipview.png?nolink&600 |{{ :resources:eval:dpg:ad9739_ads7_ace_boardview.png?nolink&600 |}}//Figure 3b. ACE Initial Board Configuration Wizard for ADS7-V2//</WRAP>
  - Start DPG Lite or DPG Downloader.
    * At the SDP-H1 settings, ensure that Evaluation board is equal to AD9739 and **DCO frequency** of around **75 MHz** should be displayed.
    * At the ADS7-V2 settings, ensure that Evaluation board is equal to AD9739 and **DCO frequency** of around **500 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 4a and 4b. 
    * When using SDP-H1, set **Data Rate** to 300 MHz and **Desired Frequency** to 20 MHz.
    * When using ADS-V2, set **Data Rate** to 2 GHz and **Desired Frequency** to 180 MHz.
  - Continuing on setting up DPG Lite or DPG Downloader, set **DAC resolution** to 14 bits. Check off the **Unsigned Data** box.
  - Select the Single Tone from the **Data Vector** pulldown menu \\ <WRAP centeralign>{{ :resources:eval:dpg:ad9739_dpg_sdph1.png?nolink&600 |}}//Figure 4a.

  - Press the download arrow and then the play button. The FFT plots similar to Figures 5a and 5b should appear in the signal/spectrum analyzer.\\ <WRAP centeralign>{{ :resources:eval:dpg:ad9739_fout_sdp-h1.png?nolink&600 |}}//Figure 5a.

=====Troubleshooting=====
This section lists items to check and practices to use when debugging any unexpected performance of a board. If unexpected results occur:
  * Check if the Voltage supply test points of the evaluation board has the correct value. 
  * 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 AD9739 evaluation board.
  * Check on the Spectrum Analyzer if the DAC clock inputs are properly driven. For 300MHz clock using SDP-H1, the spectrum analyzer should detect a weak signal at 300MHz. For 2GHz clock using ADS7-V2, the spectrum analyzer should detect a weak signal at 2GHz.  If not detected, check properly the clock source and connections.
  * Disconnect and reconnect the SDP-H1 /ADS7-V2 and AD9739 evaluation board. Reopen DPG Lite software.
