No problem for the PRS10 - there is an external pps input. For the FRK-RbO I don't have a practical solution yet, because I don't have a manual with circuit diagram found for this 5 MHz model. This RbO is actually running free, drift controlled by an external resistor set by two 10 turns potentiometers. I think it should be possible to inject a current instead. The control by eg. the Shera controller need some modifs for this purpose which I have not yet done. The time constant need to be modified too I think.
