Setting the digits of precision for TDMS logging

‎04-30-2014 11:31 AM

I can't seem to figure out a way to set the digits of precision when logging data to a TDMS file. I'm hopping to be able to reduce the file size by doing this. Any suggestions? Thanks, Cosimo

The data in a TDMS file is binary.  So you can't set the digits of precision.  If you want to make smaller files, then cast your data to Singles instead of Doubles.  You will have 1/2 the resolution, but use 1/2 the bits on disk.
