MATLAB: USRP B210 with GPSDO

b210gpsdosdrusrp

Hi,
Is it possible, with MATLAB, to configure USRP B210 to use GPSDO as ClockSource ?
I've USRP B210 with GPSDO. I'm not able to figure out how to configure USRP to use GPSDO as time and frequency reference. Currently the SDRuReceiver and SDRuTransmitter allows to select ClockSource property to be 'internal' or 'external' but not GPSDO. It is clear that the radio doesn't use GPSDO as default, because the frequency offset is so high. E.g. with GNU Radio I'm able to configure ClockSource to be GPSDO and the frequency error drops significantly.
Br, Teemu

Currently, the MathWorks USRP support package does not support a GPSDO clock source. However, if you have an alternative external clock (e.g. an Octoclock or a Keysight 10 MHz source), you can use it to provide a highly stable frequency reference for the LO.
