 The AD9129-MIX-EBZ connects to a DPG2 to allow for quick evaluation of the AD9129, a high-speed, RF Digital to Analog converter (RF DAC). The DPG2 automatically formats the data and sends it to the AD9129-MIX-EBZ,​ simplifying evaluation of the device. The Evaluation Board (EVB) runs from +5 volt and -5 volt supplies. Figure 2 is an image of the top side of the AD9129 EVB.  The AD9129-MIX-EBZ connects to a DPG2 to allow for quick evaluation of the AD9129, a high-speed, RF Digital to Analog converter (RF DAC).

-==== Initial Set-Up ====+ 
 +==== A. ACE ==== 
 +=== Initial Set-Up === 
 +1. Install the DPG Downloader, ACE, AD9129 ACE plug-in, and AD9129 software and support files on your PC  
 +2. Start ACE 
 +3. Connect the EVB to your PC and lab equipment as shown in Figure 1 above. Use a USB cable to connect your PC to the EVB, and another USB cable to connect your PC to the DPG unit.  
 +It is suggested that the basic set-up is verified before making any modifications to the evaluation board.  
 +=== Load ACE Settings === 
 +Open ACE from the start window. It can be found by following the file path to the program or by searching in the windows search bar for “ACE.” The {{:​resources:​eval:​user-guides:​ace_icon_small.png}} icon indicates the ACE software. 
 + 
 +If the board is connected properly, ACE will detect it and display it on the Start page under //Attached Hardware//. Double click this board.  
 + 
 +{{ :​resources:​eval:​user-guides:​ad9129_detected.png }} 
 + 
 +Ensure that the {{:​resources:​eval:​user-guides:​connection_icon.png}} button is green in the subsystem image under the “System” tab. If not, click it, select the AD9129, and click //​Acquire//​. Double click on the subsystem image.  
 + 
 +{{ :​resources:​eval:​user-guides:​ad9129_system.png }} 
 + 
 +On the board diagram, click //Run Example Startup Routine//. This will set the parameters for this example.  
 + 
 +{{ :​resources:​eval:​user-guides:​ad9129_chipview.png }} 
 + 
 +For further changes, double click on the AD9129 on the board diagram. This will bring up the chip block diagram, which can be used to set other parameters, such as data format and PLL Config. The PLL and DLL should both be locked and the delay cells should be checked. If not, click //Read All// in the upper left corner of the page. For more details about altering parameters, see the //ACE Software Features// section.  
 + 
 +{{ :​resources:​eval:​user-guides:​ad9129_clickview.png }} 
 + 
 +=== Configure Hardware === 
 +Configure the hardware according to the hardware set-up instructions given in the //Hardware Setup// section above. Set the frequency of the signal generator to 2 GHz, and the output level to 0 dBm. The spectrum analyzer can be configured with Start Frequency = 20 MHz, Stop Frequency 1 GHz, and Resolution Bandwidth of 100 kHz. Use an Average/RMS detector setting, and choose Input Attenuation to be 10 dB. This can be adjusted later if indications are that the analyzer is causing degradations (warnings on the analyzer itself, or third order products appearing on the output spectrum). 
 + 
 +=== Load Pattern from the DPG2 === 
 +Open DPGDownloader (Start > Programs > Analog Devices > DPG > DPGDownloader). Ensure that the program detects the AD9129, as indicated in the //​Evaluation Board// drop-down list, and select it. For this evaluation board, LVDS is the only valid Port Configuration. If it is not selected automatically,​ select it from the //Port Configuration//​ drop-down list. The //Data Clock Frequency// window may not yet show a clock frequency, but it normally does.  
 +Click on //Add Generated Waveform//, and then //Single Tone//. Enter the data rate, or DAC clock frequency, as 2GHz and the desired frequency as 200 MHz. Next, choose the //​Resolution//​ to be 14 bits. Ensure that the DPDDownloader settings match the figure below.  
 + 
 +{{ :​resources:​eval:​user-guides:​ad9129_dpgd_singletone.png }} 
 + 
 +Next, in the lower portion of the screen, select //Single Tone// as the Data Vector. The other options can be left at their default values. The Data Clock Out (DCO) frequency from the AD9129 should be reported in the Data Clock Frequency window as roughly 500 MHz.  
 +Make sure the DPG2 unit is powered up and the AD9129 eval board is plugged into it correctly. Click the Download button ({{:​resources:​eval:​dpg:​ad9129:​Download.png?​15|}}) to download the pattern from the computer to the DPG2 unit, wait for the Play ({{:​resources:​eval:​dpg:​ad9129:​play_pattern.png?​15|}}) button to become active, and then click the Play ({{:​resources:​eval:​dpg:​ad9129:​play_pattern.png?​15|}}) button to begin vector playback to the AD9129.  
 + 
 +=== Result === 
 +The final result should be a clean 200 MHz tone as shown below. To best verify the set-up, match the settings seen below on the spectrum analyzer screen.

 +===== ACE Software Features =====
 +The ACE software is organized to allow the user to evaluate and control the AD9122A evaluation board. The “Initial Configuration” wizard, which is only available for certain boards, controls the DAC and PLL setups. Block diagram views of the board and chip contain elements that can be used to vary parameters like ref current and data format. These parameters can be changed using check boxes, drop down menus, and input boxes. Some parameters do not have settings shown in the diagram. Double click on the parameter to view the available settings, seen with the NCO settings below. ​

To use, check the “Record Sub-Commands” checkbox and press the record button. Changes in the memory map, which are bolded until they are applied to the part, are recorded as UI commands by the macro tool once the changes are made. Changed register write commands for the controls are also recorded. Hit “Apply Changes” to execute the commands and make changes in the memory map. To stop recording, click the “Stop Recording” button. A macro tool page with the command steps will be created. The macro can be saved using the “Save Macro” button so that it may be loaded for future use.

 +The raw macro file will be saved using ACE syntax, which is not easily readable. To remedy this, the ACE software download includes the Macro to Hex Conversion Tool. The user can choose to include or exclude register write, reads, and/or comments in the conversion. The file pathways for the source and save paths should be the same, except that one should be an .acemacro file and the other should be a .txt file. The “Convert” button converts and opens the converted text file, which is easier to read. The conversion tool can also convert back to an .acemacro file if desired. ​
