Refer to the user guide of the eval board for setup steps, specifically on page 3 of the AD8460 Evaluation Board User Guide.
Make sure that you have your SYNC clock running to have an output signal.
If AWG mode is also used, the connection is through the FMC connector P7.
Please follow the steps as mentioned on page 14 of the user guide, 'Using the Arbitrary Waveform Generation Mode' section.
In the AWG mode, 14-bit digital input data representing the desired waveform is loaded through the parallel interface (pins DB13:DB0) and clocked in on the rising edge of SYNC, corresponding to conventional parallel mode high-speed DAC usage to update the output. The AWG mode is used when complex waveforms, specific edge speeds, or digital predistortion are required
Please refer to page 19 for troubleshooting errors.
AWG mode output does not update.
a. Sometimes one Download → Play sequence is not enough to display the results. Monitor the output on an oscilloscope and repeat the steps until the output is displayed correctly.
b. If the output is repeatedly updating to a square waveform, generate a Copy of the desired vector in the vector generator tool and repeat the Download → Play sequence until the output is displayed correctly
