The combination of clock_source=external,time_source=gpsdo is not available out of the box, but can be enabled by patching the MPM source code (n3xx.py). This is considered an advanced and unsupported use case. Read the appropriate source code for a description of drawbacks. Using this ...

uhd::device::RECV_MODE_FULL_BUFF, timeout ); It looks like the scheduling of the USRP N200 does not work in UTC. Whenever the value of stream_cmd.time_spec becomes large, sampling starts right away. I have found a work around (first code sample), but I would rather schedule ...
