Hi Bob,
Yes, I did notice the prior thread about this. At the moment, I have
been looking at it using the spectrum analyzer function of my HP 8935.
With the reference level set to 20 dBm, I am getting a reading that
varies from 6.99 to 7.37. I am trying to figure out whether this is
normal based on the prior comments on this issue.
I am going to see whether the signal level is adequate to drive the
Cushman 5110. If so, the MV89 will become the new reference for that
unit. At present, it looks like the MV89 is within 1 Hz even without
the application of the reference voltage. Fine tuning will have to
await a trip to the local parts store to get a multi-turn pot.

Hi
The big question is weather yours has the "capacitor of death" problem or not.
If it has the bum capacitor(s) in it, you will need to pop it open and replace the cap. I
would check things out before moving forward.

I just received my first Morion MV89A. It came attached to a piece of the
original PC board.
I wonder how others have mounted theirs. One option seems to be to get a piece
perf board (perhaps with solder pads). Another might be to leave it on the
original PC board since that seems to have a nice ground plane and enough of
the board remaining around the edges to mount the whole thing on stand-offs. I
could remove the dozen or so capacitors and resistors on the original board.
I am thinking of using at least one of these in an existing piece of equipment,
so something simple is desirable.
Thanks for any suggestions.
