回复： Write waveform timestamps with data in TDMS file

[djroseman]

Hello,

I am attempting to write data from an array of waveform data derived from a multi sample DAQmx acquisition, but I have found where I have used the get date / time function within my while loop passed to a TDMS Write in series with another being passed the waveform data, that I have many more data points than timestamps, as I am getting a timestamp then the list of sampled points.

I am looking at using the timestamp data from the waveform, but I'm not sure how to make this work.  Attached is an example where I have attempted this, but just managed to obtain mismatched data types.

Could anyone please offer some advice on how to get the following structure in my file:

timestamp of sample | channel 1 sample | channel 2 sample | .... | channel N sample

Thanks

Dave

I'm not quite clear about your use case in the attached VI. However, you should give input of channel names to the 2 "TDMS Write" nodes since they have different type of raw data.

That was the thing I was missing - adding that built my file as expected.

Thanks for your assistance
