Hi,

I also would use an adjustable PS and checking the output RF level to see
if the RF level is increasing while incraising the DC voltage... when the output amplitude is not changing anymore then it should be the operating DC voltage....
or chk the outcoming Ref DC voltage.

 I'm getting a signal out with 3.3vDC in.  I haven't tried to test this
 higher. 
The data sheet at 
 http://www.vectron.com/products/ocxo/c4550.pdf
hows 3 common input voltages.  3, 5, and 12 V.
It also says 3 W warmup.  So I'd be tempted to see how much power it used as 
 cranked up the input voltage.  (1 W steady state.)
