Save data in Labview NXG

[Dr.pink]

hello,

I am doing experiment using USRP and Labview NXG. Now I can get data but I need to save them to a .txt file. I tried some methods but the problem is the system only save the data in last moment. All the previous data is covered. 

So, is there any way to save all the data in the whole experiment? It is better to save the timestamp together. 

thanks

Figure2 might be helpful for you. Do you really need txt?

I recommend to work with TDMS because RF data would be large in most case.
