This user guide describes both the hardware and software setup needed to acquire data capture from AD9114-DPG2-EBZ/AD9115-DPG2-EBZ/AD9116-DPG2-EBZ/AD9117-DPG2-EBZ or AD9714-DPG2-EBZ/AD9715-DPG2-EBZ/AD9716-DPG2-EBZ/AD9717-DPG2-EBZ evaluation board to characterize AD9114/AD9115/AD9116/AD9117 or AD9714/AD9715/AD9716/AD9717 8-/10-/12-/14-bit 125Msps low-power high-speed digital-to-analog converter.
This guide shows how AD911x-DPG2-EBZ/AD971x-DPG2-EBZ works with SDP-H1 controller board developed by Analog Devices. Link to the previous user guide document is provided for customers who still have the DPG2 or DPG3 controller board.

This section lists items to check and practices to use when debugging any unexpected performance of a board. It also provides information on how to check for proper operation when using the modulator in the signal chain. If unexpected results occur
If the common-mode voltage is not as expected, unplug the board and check the resistances at R13, R14, R52, and R53 for the correct values of the particular board. If a proper reading is not present, unsolder J13, J14, J19, and J23, which removes the resistors from the parallel connection with 1 kΩ/100 Ω at the input of the modulator to measure the individual resistances of those components. Check if the resistance values are still incorrect and if so, change out for the appropriate values listed above. If not, try resoldering the jumpers and test again to make sure there was not a problem with the previous connection.
