Why do you think you need to convert to an array? Just wire a single multiply function up to the waveform data type. The multiply is polymorphic. You did not even need to index out the separate 1D arrays. You could also apply a custom scale with DAQmx and skip the multiply function all together.
well i tried using Export waveform to spreadsheed vi. it works but the time stamp seems to be not correct. only gives me minutes and seconds not the date and hours
I really don't care what you are showing in Excel. Open the file as .txt (i.e. with Notepad) and look at the date/time column there. Do NOT open it first in Excel and save it. In fact, don't even give it an xls extension.
