According to the documentation I have, pins 2, 4, and 5 are all tied together internally
I think you may be correct. My recollection was that it needed to be done at the connector, but I may be mis-remembering. Worth a check, though.
If you have Pin 6 ranging from + 5 V to - 5 V with respect to Pin 2 and are only getting 50 mHz of frequency change, then yes, it appears that the EFC in that oscillator is not working normally.
Note that different versions of the 10811 have different nominal EFC slopes -- most are nominally 0.1 Hz/V (1 Hz/10 V), but some are nominally 0.25 Hz/V (2.5 Hz/10 V) (05071-60219, 05071-69219, 10811-60158, 10811-60159, 10811-60160, 10811-60164). The 10811 D/E Option 100 and Option H41 (10811-60125, 10811-60131, 10811E Option H41, 10811-60133, and 10811-69133) are "Not Specified" for EFC. I do not know if this means they do not have EFC, or only that they are not guaranteed to meet any particular EFC slope. I think the latter is more likely -- perhaps Rick knows and will comment, or someone here has an Option 100 or Option H41 oscillator and can measure it.
