I looked at two units of the FE-5680, two units of the > Efratom FRS, and one Datum LPRO. Which variety of the FE-5680A did you measure ? That with the output frequency adjustable in a wide range, with a master oscillator at 52..ish MHz, or the latest one, derived from a 60 MHz oscillator, where you can just tweak the output frequency with commands to the DDS ?
