most efficent way to log SCXI thermocouple data

[faustina]

I want to log thermocouple data collected using SCXI-1102C cards.  It is for an extended period of time (2 weeks) but I'm only collected periodically (once every 10 min).  I'm only collecting about 15 channels of data and I'd like to sample as slow as possible without having aliasing problems.  I was thinking of using the Configure Logging (TDMS) VI as used in the following example https://decibel.ni.com/content/docs/DOC-11300.  However, when I collect the data it must be timestamped using IRIG.  Is using the Configure Logging (TDMS) VI overkill for my application?

The way to avoid aliasing problems is have some hardware low-pass filtering on the inputs. In terms of your other question, the real issue is, "What is your data worth?"

If it is worth going to the trouble to use TDMS, it's probibly worth the effort to really do things right and put it in a database.
