DAC output has 2.6V DC, but no sine wave

I have a single DAC design runing on a ZCU111 eval board. When I write sample data to the DACs AXIS interface, I get 2.6V on the output of the XM500 DAC0 output, but no sime wave.

Is the 2.6V DC expected? Any suggestions on what to debug for the abcense of the sine wave?

Any comments are appreciated.

Yes, please try with the evaluation design.
likely the issue is that the RF PLLs on the board are not programmed by you so the tile will not have started.
