DAC Converter

Thanks for your answer

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

I see what you mean but I hane not yet foud this code because I have not installed all the cds.

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

I take the clock I have defined: I make an output on a pin, and I put it on J12.

My settings on j18 are PIN 7 and 8

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.

Ok, I have changed my clock:

signal compteur: std_logic_vector(11 downto 0):="000000000000" ;
clk2<= compteur(11);

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.

Can I see an output signal? Now I have some pics alternatively plus and minus of the same amplitude (1 V). I do not understqnd why there is the same amplitude for a different code of 14 bits....

Or Have I to put it in an AD converter and see if my bits are right? But in this case there is a loss of data so I am not sure to have what I want to see even if the DA conversion is correct. Right?
