Hi Folks,
I am just wondering whether the ZYT-GPSDO-2 LCD SYMMETRICOM 10MHz 1PPS OCXO GPS Diszipliniert Oszillator offered in AliExpress provides more phase stability in comparison to the BG7TBL GPSDO GNSSDO GNSS Disciplined Oscillator Disciplined Clock with 10MHz Output, also offered in AliExpress.
The BG7TBL GPSDOs we tested two of those each connected with a separate GPS antenna to synchronize two RF-synthezisers at 110 MHz.
We compared the phase drift of the two 110 MHz signals with a amplitude- and phase comparison meter.
We measured a phase drift permanetely variating between of more than 180 deg within of app. 60 seconds.
The RF-synthezisers keep their phase within 1 deg when connected with the same 10 MHz reference signal -> so, they are ok, as well as the phase comparison meter.
My question would be if with the ZYT-GPSDO-2 LCD SYMMETRICOM 10MHz 1PPS OCXO GPSDOr better results can be expected in terms of phase stability?
Thanks DJ2XH
