    Create an SDRu receiver System object. Set the pulse per second (PPS) signal source to be the PPS signal from a GPSDO.

    rx = comm.SDRuReceiver(Platform ="X300",IPAddress ='192.168.60.2',...
                     PPSSource="GPSDO",ClockSource="GPSDO",...
                     EnforceGPSTimeSync=true,SamplesPerFrame=20000);

    Get the current USRP radio time.

    GPSLockStatus = 0;
    while ~GPSLockStatus 
        disp("Trying to lock to GPS constellation ...");
        GPSLockStatus =  gpsLockedStatus(rx);
    end  
    Trying to lock to GPS constellation ...

    disp("GPS Locked");
    GPS Locked

    rx_data = rx();
    USRP time synchronized to GPS time

    radTime = getRadioTime(rx);
d = datetime(radTime,'ConvertFrom','posixtime',...
'Format','MM/dd/uuuu HH:mm:ss','TimeZone','Asia/Calcutta');
fprintf('The current USRP radio time is %s',d)
    The current USRP radio time is 07/27/2023 16:29:31

    release(rx);
