[time-nuts] Morion MV89 output level?

Got my replacement FE-5680 and a MV89 in from Nichegeek.  I figured 
I'd better power up and check the MV89 before I let 'em know 
everything was ok.  The MV89 is warming up nicely, the current is 
down to 290 mA (and still dropping), but the output seems low; about 
40 mV RMS as measured on a scope with a 10Meg 10x probe.  (Datasheet 
spec is +7 +/- 2 dBm.)  The output is too weak to reliably trigger my 
5345A counter.

The reference voltage measures 4.90 VDC.

If anyone can make a quick measurement on their MV89, I'd appreciate it.


thanks!
