Hi,
I have an analog pressure sensor that is capable of reading data at a frequency of 1K Hz. I would like to collect the pressure sensor data as a function of time at the frequency of 1K Hz (the maximum frequency for the pressure sensor). I would then like to read the pressure vs. time data in a spreadsheet.
I have been able to record the pressure vs time however the maximum frequency I am able to obtain has been ~60 Hz using the DAQ assistant(run continuously) while using the elapsed timer. I believe the DAQ assistant is running correctly, but the elapsed timer is not quick enough.
I am using a PCI-6280 DAQ board, I believe I would like to use the internal clock on this DAQ board as the timer to collect this data. I have had no luck thus far, any ideas on how to do this?
I have attached my VI for reference.
Thanks!

HI,
Please find attached Sanpshot, this will log the analog pressure sensor data with time (save to .xls file)
Hope this helps
Regards

Thanks for your help, but I do not appear to be setting up the cluster correctly. Could you give me some advice on how to do that, or possible attach the vi, I am using Labview 7.0, but can use 8.0 is necessary.

I have have tried the suggestions, but I am still not reaching my initial goal of reading pressure vs time at a frequency of 1 KHz and exporting this to a spreadsheet. I would like to have a spreadsheet that has time values at 1 KHz, so 0.001, 0.002, 0.003, etc with the corresponding pressure values, how would I record time in this manner?
Thanks for your help thus far!
