Help with saving time stamps to "write to measurement file" excel format.

[connor016]

I am having problems saving the timestamps from my data to the write to measurement express vi for excel.  My incoming data is converted from dynamic data to a 1d array for processing, which I understand you lose the time stamp data. I added a new array for time stamps but this array then cannot be converted back to the dynamic data that is requested to go into the write to measurement file express vi.  I would prefer to leave the data in an array to be saved rather than converting it to a waveform so is there any way to add the time stamps from my 1d array back into the write to measurement file?

Why don't you want to convert the dynamic data to a waveform data type? This retains the time stamp and dt. You can easily use the Get Waveform function of you want the y array. The Write to Measurement function will accept the waveform data. Of you insist on using an Express function, you must accept its requirements.

I am taking data from the analog inputs and monitoring it realtime while it is then being saved to an array of scalars that averages the dynamic data so I don't have as much data to deal with.  When converting to a waveform can you reduce it to essentially one value of the average input?

Yes.

how do you go about that while keeping the data type waveform?  mean changes it to a double.and does not retain the time information.

I set it up to build a waveform now but I am still having issues with it saving the correct timestamp.  The time just incriments for every second (as it did before converting the dynamic data to the waveform). I attached a screenshot.

I think I misunderstood what you were doing. You didn't attach the file you are saving but I think the issue is with the dt and not the timestamp. When you reduce the samples to the mean, you have a single sample and the dt is meaningless. You could use the tone out takes for one iteration of your loop as the dt.
