Hi Vladica, I think the overflow means that the host pc cannot process the data flow fast enough or you might need to set the parameter timeout of
recv(buff_ptrs, num_rx_samps, md, timeout) a bit longer?

The problem is that I get an overflow condition every time I try to receive more than 10k samples. According to the data for the N321, it has 1 or 2 GB memory, enough for 100k samples, so this number of samples can be stored in the RAM and than sent to the PC. Unfortunately, this is not happening. Is there a workaround for this issue? I use rx_timed_samples for this. With 10 Gbps Ethernet everything is OK. Also, I want to ask if it is possible to trigger the sample acquisition on a given input signal level, i.e. threshold?
