Hello Everyone. I am Using NI-USRP 2954 for some experiment and my received signal is received at a rate of 2.5MS/s. I need to keep on collect the data for atleast few second. I am using "write to measurement file" vi from File I/O group for the data logging. However when I am collecting data it is gathering data very slow. There becomes a huge difference between number of transmitted and received chirp. If I am not collecting the data then there is no difference between the transmitted and received chirp, i.e., if i am transmitting 10 chirp in a duration of time i am getting 10 chirps at receiver. So, what is the way to to acquire the data in such a high rate.

Yes i used tdms file functions, but it is saving data with .tdm function not iwith .tdms.

All we got from you is an image showing an ExpressVI.

Please provide some (real) code aka VI...

(Please downconvert when you use a very recent LabVIEW version (File->Save for previous). I prefer LV2019.)

Best regards,
