TDMS wf_start_time with milliseconds

[sez]

How can I include millisecond information to waveform start time information within my TDMS file?

My timestamps look like: 10/17/2016 08:59:34.000 AM

Hi sez!

You can do that with the TDMS Set Properties.vi.

Please also check out these two links:

• How Do I Set the File, Group, and Channel Properties of my TDMS File?
• TDMS Set Properties Function (List with TDMS Properties)

Thanks for your reply Wolfgang,

I am using DAQmx Configure Logging.vi after DAQmx task creation that setups TDMS file handling. Not using any of TDMS low level functions.

Is there any way to include millisecond information to wf_start_time with DAQmx Configure Logging.vi method?

Hi sez!

The DAQmx property do not support to set properties in the TDMS log file.

The only thing you can do is to create a file and write the start time property to this file. The DAQmx driver opens this file again and log the data into the file.

Basically you can do this but I would prefer the low level solution with the TDMS VIs shown in the post before.

Best Regards,

Wolfgang
