An DAC code that works should be the DA/AD performance test provided in the factory design.

I see several points why your test may have no output. Unfortunately none of same can be seen from the information you provided:

1. I don't understand which pin or other source provides the clock to the DAC,

2. As you have a 1.5 Hz divided clock, the DAC ramp has a periof of 3 hours. It may be difficult to observe.

3. The DAC SMA output connector is transformer coupled with Mini-Circuits ADT1-1WT, that has 400 kHz lower cut-off. You can't see any LF or DC signal here.
