AD9166 plus ADS7-V2EB

Are you planning to use internal clock with external reference?  Your question is not clear to me. 

HMC7044 provides SYSREF and reference clock to FPGA. sampling clock is supplied by ADF4372. Could you explain your actual issue.  

Thanks for getting back to me, I was trying to use the following settings to load 2 files via DPG but the set up crashed after couple of minutes.  

The ACE settings are below:

I have now added an external 10MHz reference via J61 at 0dBm level but didn't changed any resistors. It seems more stable and doesn't crash but my question is in this mode do I need to change any of the 0R link positions,

How is your sync status in DPG? Can you see the desired output? 

In both cases I can see the required output but with the All internal clocking setting, the system crashes after a couple of minutes. Also I can see the sync status as locked in both cases. This stops when the system crashes.

So my question is, 

Is it ok to set board clocking scheme to Internal clock plus Ext Ref clock (10MHz 0dBm), via J61 and not change any of the 0 Ohm links, plus do I need to add any further ref signals with this scheme

Thanks,

You can use internal clock with external reference. Make sure your reference signal is not drifting or it is not feeding in a weak signal. Your spectrum analyzer and reference clock signal generator should be synchronized.

Also make sure you have all the updated drivers installed for your system.  

Many thanks for your help, I understand and I have the reference connected also to the spectrum analyser

Hi,

I am trying to use the same ADS7 board and AD9166 DAC after a short break but when I initialize the DPG download software I see a scan take place then returns an error saying no boards are connected. I have tried this with multiple DAC boards and see the same error. Nothing has changed in my set up.

Any thoughts?

Thanks

Alan

 Try to reset your ADS7. Check for firmware update. If you have another ADS7 you can plug in that one with your AD9166.
