@Logan_K As for the actual aging of the components... I am not surprised that the warranted specification is much wider than the actual performance of your unit. Generally NI is very conservative with their warranted specifications to ensure that >95% of devices will pass these limits. Assuming a roughly gaussian distribution of performance across devices, the majority of devices would be expected to have significantly less drift than the worst case. Specifications labeled as "typical" are usually a better representation of how the majority of devices will perform.
I know that and I agree with you regarding this, but are the given numbers for the offset time drift OK? If you are with NI can you please check this?
Thank you
