stability in the clock of a PCI 6043 E

[emma]

Hello!
I've got a PCI NI 6043 E card, I found a drift in the internal clock of 5.9e-6 sec/sec. I would like to know how stable is it.
Thank you very much!

Emma,

I believe you may be misquoting the model of your DAQ card. I don't believe we have a PCI-6043E. In any case, the base clock accuracy can be found for most boards in the Specifications Appendix of the User Manual. You can find your board's manual at www.ni.com/manuals. In most cases, the base clock accuracy is +/- 0.01%.

Hi Justin

Though this was some years ago:

I do not find in the manuals which error sources are included in the named "BaseClock Accuracy"

Is temperature drift and power supply drift included in that??
