I am acquiring impact
data using NI sound and vibration and NI cRIO 9233. I am averaging the
data over 10 hits and saving it to Ascii, LVM files. When I open the
file in excel I see 11 sets of readings. The frequency resolution is 1.25Hz
and range is 0 - 1562.5Hz that gives me 1250 divisions, which means its
storing each of them separately. Why is it doing so and does it store the
averaged data or just individual runs? After the final hit am I seeing the averaged data or the final hit.
Also could I possibly set a condition where
the data is accepted by the software only if the hit is good and I want
to accept it. May be like a condition where I could accept that data by
clicking a push button after looking at the averaged coherence and FRF? And if possible could it be inbuilt into signal express impact measurement system? Attached is my acquisition template and also
the data in ascii format. I need to get this going as soon as possible. Please help me out here.
