Not sure what that is. Can you please guide me?

I tired using Format into string, but then the result text file includes time stamp 4 times for each line of data, instead of doing just once.

I have this .vi that converts the .TDMS to ASCII. However at the moment the time format is "00:00.000001 5.2041 0.2388 -0.0004 0.9106" for each line. How can I make it in seconds in scientific format so the data will show as "1e-6 5.2041 0.2388 -0.0004 0.9106"? Also how can the headers be added into the ASCII file? to_Asci_2.vi

They use the same channels. OK, thanks. Good to know I cannot run two task with same channels simultaneously.

Thanks for the .vi. Seem like the notifier is being passed to the new loop, as new .tdms file is created, but the loop inside the case structure is not being executed, hence the data is not being written into that file. The count stays at 0.

Not sure if I understand... I want the loop when meets condition not to stop but carried on. At the moment there is an "OR" block that is connected to the LED and to the stop loop.

Would it be possible, not to stop the recording of the low sampling rate, while the high sampling rate is also recording after the trigger?

This is great. Many thanks for your help. All makes sense.

Not sure if this is the right way of doing it. R_R_9_MTDS_Split_Rec_trig.vi

Hi I want to create a logic to trigger an event with Case Structure block with Greater Than block, where the "x" value for the Greater Than is input coming from one of the channels value. I used Get Waveform Components to extract the "Y" value from waveform and wanted to use this as an input into the "x" for Greater thank block, however Case Structure does not accept this type. Any thoughts?

So effectively I want to create a variables with file path and samples number.

In task there is the option to split the file by spanning multiple files over the given number of samples. Any chance I can do this with the LabVIEW code, so I have control over the file names and samples per file? R_R_9_MTDS_2.vi

Hi, I have this .vi project where I acquire data from the NI-Module and save it to TDMS. The acquisition rate for the TDMS is in the Resample Waveform block. However when I examine the TDMS in excel it does not match the expected number of samples recorded based on the chosen acquisition rate. I also tested it without the Resample Waveform block, when the rate is directly set in the Task, the TDMS again does not match the expected rate. Any thoughts? Regards R_R_9_single_channel_1.vi

How do I postprocess automatically, so that the .tdms is converted into the delimited .txt file that includes the time and all channels involved columns. Also to have headers. See the .vi attached. R_R_9_MTDS_2.vi

Do you mean, to save into MTDS, and postprocess to text?

Hi, What would be the most efficient way to record data in sampling rates >1MS/s into the .txt? I tried to use Write to Measurement File but after a few seconds it spits error, saying that I run out of memory. Please have a look at the .vi. R_R_3.vi
