Accuracy of PXIe-6614 ?

[MaxiMuz1979]

I did not find direct specification on clock accuracy . There are "Temperature drift only" and "Temperature and 1 year drift (excluding retrace error)", but there is not accuracy information.

Did anybody encounter with this task ?

Specifically what accuracy info are you looking for?

I am looking for info .. about base clock accuracy

Several potential contributors are listed on page 6 of the specifications.   I don't know with certainty which items are purely additive, but the worst case is to assume you need to add the +/-75 ppb accuracy tolerance to the +/-10 ppb retrace error and then perhaps also the +/-50 ppb long term stability (though maybe that's already included in the accuracy spec?).

Worst case seems to be +/-135 ppb or 0.0000135%

It is question to the producer : do we need to add 'long term stability' to the common accuracy ?
