TTL triggering tdms AI Data Acquisition

[BCar]

Hi,

Currently as a part of my research work, I am trying to acquire data in a .tdms file from an analogue channel triggered synchronously by each rising edge of a TTL signal input by a signal generator to PFI0. So to be clear, I won't be having any reference of time. Data will be sampled each time a rising edge of the TTL signal is input. Therefore the sampling frequency would ultimately be determined by the frequency of the TTL signal I input by the signal generator.

Initially I was trying to begin from some examples available, however no luck so far. I hope you guys can help.

Thanks in Advance,

Carl

Hi BCar,

Here is a link to a tutorial on how to set up triggering with DAQmx:

Figure 11 will probably be most helpful, because you'll need to use a while loop for collecting many samples.

Hope this helps!
