There are two types of FE5680's. The older style used an ANALOG approach to controlling the Rb. The newer version changed the circuitry so that frequency control was done with a DDS device by means of sending a digital word to the DDS and thus changes frequency. The digital version does not permit any ANALOG control.
Instructions for determining which version one has would make it easier for potential users to decide if they want a controller. Preferably, without opening it up or turning it on, if that is possible. Can you tell by the label, for example?
