Thank you very much for your reply!
To clarify though, the only issue that is actually preventing us from sampling at a higher rate is the fact that we we have:
Fs = 3000;
dq.Rate = Fs;
nSamples = 0.02*Fs;
dq.ScansAvailableFcnCount = nSamples;
Given that Shengjie, Mauro, and Agostina all had the exact same issue as well-- a 10 Hz read limit exactly for everyone involved in this thread-- I do not believe this is an issue arising from our own use case. Unless I am misinterpreting line 1514 in my earlier screenshot, the 10 Hz limit is being set within the source code itself.
Given that we also have our setup working perfectly with the old toolbox, this convinces me further of that possibility.
If you have any other information, it would be greatly appreciated. I am happy to contact technical support if needed.
Thank you again for your time!
