-The AD9121/​AD9122 Evaluation Board connects to the Analog Devices Digital Pattern Generator (DPG) or System Demonstration Platform (SDP-H1, PN: EVAL-SDP-CH1Z) to allow for quick evaluation of the AD9122. The DPG or SDP-H1 allows the user to create many types of digital vectors and transmit these at speed to the AD9122 in any of the AD9122 operating modes. The AD9122 evaluation board is configured over USB with accompanying PC software.+The AD9121/​AD9122 Evaluation Board connects to the Analog Devices Digital Pattern Generator (DPG) or System Demonstration Platform (SDP-H1, PN: EVAL-SDP-CH1Z) to allow for quick evaluation of the AD9121/AD9122.

 ==== Software Installation ==== ==== Software Installation ====
-The DAC Software Suite plus AD9122 Update should be installed on the PC prior to connecting the hardware to the PC. The DAC Software Suite is included on the Evaluation Board CD, or can be downloaded from the DPG web site at https://​wiki.analog.com/​resources/​eval/​dpg/​dacsoftwaresuite. This will install DPGDownloader (for loading vectors into the DPG2) and the AD9122 SPI Controller application. However, ACE, a newer evaluation software from ADI, is the preferred evaluation software over the legacy SPI control graphical user interface (GUI). ACE can be downloaded from the ACE website at www.analog.com/​ace. The ACE plug-in for the evaluation board, which is also required, is available for download on the AD9122 eval webpage in the software section at http://​www.analog.com/​en/​design-center/​evaluation-hardware-and-software/​evaluation-boards-kits/​EVAL-AD9122.html#​eb-relatedsoftware. ​+The DAC Software Suite plus AD9121/AD9122 Update should be installed on the PC prior to connecting the hardware to the PC.

 ==== Hardware Setup (DAC OUTPUT) ==== ==== Hardware Setup (DAC OUTPUT) ====
 Once the DPGDownloader software is installed, the hardware can be connected as shown below. A single 5V power supply powers the evaluation board. The power supply should be able to source up to 2A to cover all of the board’s operating conditions. A low jitter clock source (< 0.5psec RMS) should be used for the DACCLK. A sinusoidal clock output level of 0 to 4dBm is optimal. By default, the DAC outputs are connected to SMA connectors for evaluation. Both DAC outputs are available. Later in the document, the modifications for observing the modulator output and different clocking options will be shown. Once the DPGDownloader software is installed, the hardware can be connected as shown below.
