We use NI PCI-6221 to measure some transients. What we want is to change the sample rate while the measurement is ongoing and keep the right timestamp. For example, We measure for the first 10 seconds with 100kS/s, for the next 90 with 1000kS/s and for the next 900 with 10S/s.
Is it possible to use the internal clock to do this? If yes how?

Dear kypros,
You can technically implement a solution to this application by creating a pulse train from a counter output. You can change the frequency of this cunter output on the fly and correlate your acquisition to this counter. Feel free to look at the examples in our developer zone. You might find this example useful:

Thank you. Although i have Labview 8.6 and can't try the example i got the idea so i will try something like this and see if it works for my problem.
