Time Stamp on output file using Tektronix Edition

[funkytuqe]

Hello, I am using NI signal express 2.5.0 with Tektronix edition 1.1.0

I am using a Tek TDS2004B scope to trigger, then measure the Mean and P-P of the acquired signal, then output to a file using the Save to ASKI/LVM (saving to ASKI, there is no LVM option for me for some reason).   I would like to have a time stamp in the output file for each mean/p-p output, but the file only shows the measured values and not a time stamp associated with it.    I have also tried the auto recording option with the same result, I get a test start time/date in the header but no time stamps for each acquisition of mean and p-p values.

How can i get the time stamps to show up in my data output?

Attached is the project i am working from.

Thank you.

Hi funckytuque,

You aren't seeing any time information because you are trying to save data that doesn't contain any timing information.  You are saving two signals that are arrays of doubles, which don't have any timing or X column information, rather than waveforms, which do.

Attached you'll see what happens when you try to save a waveform data type:

Thank you Eric, your time taken to reply is much appreciated.

I tried to look at the project you attached but i get this error (see picture).  Does this mean i need an updated version to view your project?

In addition I gather by what your saying, it would be best to capture the waveform first then post process for mean/p-p.   That way the values will have a time stamp associated with them which can be included in the output file.

Thanks again.

Hmm, I'm not positive what that error means.  The TDS 2000B isn't in the project, we're using the 2004B step.  Interesting. As far as what version, I am using Signal Express 2010, and just installed the techtronics edition 2.5.1 on top of it.

Attached is the screen shot of the project, it should be enough to show you what to do.  Note the two different icons, the DBL indicating a double data type, which does not have timing information, vs the graph for the waveform datatype, which does have timing information.
