 The outputs of the AD917x can be captured at the SMA connectors: J1 for DAC0; J2 for DAC1; and J3 for CLKOUT.
+Some applications may be more sensitive to clock spurious. To prevent any spurious coupling from the onboard HMC7044 onto the AD917x output, the HMC7044 may be kept in reset:
+  - reset the board in ACE (Reset Board button in the "AD917x-FMC-EBZ" view)
+  - in the Wizard, under Eval System Option select chip to configure: "AD917x Only". This will keep the HMC7044 in reset after step #1.
+  - Under DC Test Mode, select the option "Main" or "Channel" to enable the NCO-only mode
+  - Under SERDES Interface, set the link mode and interpolation (this will apply a clock to the corresponding datapaths. E.g. dual-link to enable both datapath0 and datapath1, that would feed DAC0 and DAC1 respectively)
+  - Under Clock frequencies, set the Input Data Rate to set the DAC Clock Rate. DAC Clock Rate = Data Rate * Interpolation.
