Need some Input and help for this plz.
Im using shared variables to log data into TDMS database in Labview
Im also using cFP and cRIO to log data from diffrent instruments(Flow,Pressure,Tempratur)
I want to sample 5000 samples over 10 s from cRIO (500 Hz for pressure).
At the same time i want to sample flow from cFP at 2Hz.
My problem is how i can sample and store both these in the same database using TDMS, and at the same time have them synchronized for logging later .
Any Ideeas??

Again, TDMS is not a database - by putting the word "Database" in the subject line you are limiting the number of people that will look at it...
To do what you need should not be a problem assuming that you have timestamps associated with the data as it is acquired. The timestamping of the data will keep them aligned. For example, with a waveform you have a T0 value (when the acquisition started), a DeltaT (how much time there is between datapoints) and an array of data values. These values of the two waveforms will exactly define the time relationship between the two signals.
