Writing Units and Description to a TDMS File in LabVIEW

[Chris_VH]

Description

Description-Separate-1

1. Overview:

This example writes a simulated signal to a TDMS file and adds channel information 

2. Description: 

The TDM data model offers three levels of hierarchy: root, group, and channel. Each level accepts an unlimited number of user-defined attributes, which makes the files search-ready.

This example demonstrates how to write units and/or description to the channel level using the TDMS Set Properties function.

3. Requirements

• LabVIEW 2012 (or compatible)

4. Steps to Implement or Execute Code

1. Run Write TDMS with channel properties LabVIEW 2012 NI Verified
2. Select a place to save your TDMS File
3. In the TDMS File Viewer select a channel and verify that the "Description" and "Unit_String" properties are present

Thanks so much for posting this , it helped me a lot on my project

chris this looks nice but what if you want to have different  units for each signal. This makes the units the same for all.
