Synchonously write to TDMS from two loops

[Der_schorsch]

Hi everyone, I have searched the forums so far to no availe, thus I'm posting the question here: I'm using a cdaq to give out an analog signal and record an analog signal, however at two different sampling rates. I'd like for both signals to written into a Tdms so they have the same timestamp (the idea is to have a same time basis of output and input), without having to use a hardware loop and an additional analog input. After my search I'm thinking that that is not possible. Or is it? I'd be very thankful for a push in the right direction

Hi Der_Schorsch,

it is possible to select the same source for the sample sampleclock. Then, analog Input and analog output are working at the same event. Use the trigger event. The analog Input (Spannungstast) starts to trigger, if the first analog outout event occurrs.

I hope this advice helps you.

Best Regards, Fabian
