Hello everyone, [USRP E310]
We need to capture some 300 Hz signal for a long period of time (up to 15'), as long as a GPIO is '1'. Minimum configurable bandwith is 286 KHz, what makes us sample the data at 286 KSPS. At this sampling rate, every 15' of capture results in a file of 2.2 GB. The following error appears randomly, sometimes in the first capture, some times after several sequencial captures, and the resulting capture is flawed: *"Got an overflow indication. Please consider the following: Your write medium must sustain a rate of 2.28 MB/s. Dropped samples will not be written to the file. Please modify this example for your purpose. This message will not appear again."* Our "write medium" is a USB 2.0, that should support data rates well above that one. I found the recommendation in this thread <http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2017-March/024178.html> of configuring "NUM_SAMPS_AND_DONE" but in our case we don't know how many samples have to be captured beforehand. Any recommendation? Regards, Brais.
