    Open Live Script

    Create an SDRu receiver System object. Set the clock source to be the 10 MHz clock signal from a GPSDO.

    rx = comm.SDRuReceiver( ...
    Platform="N320/N321", ...
    IPAddress="192.168.20.2", ...
    ClockSource="GPSDO");

    Get the lock status of the USRP radio to the 10 MHz clock signal.

    status = referenceLockedStatus(rx)
    status = uint32
