I forgot to mention that it can be removed nicely with hot air, and has
the very nice property that you can solder things that are coated just
in case you should make a misteak. it is soft. I did not know the
epsilon or tand.

Look at 3M Scotch-Weld Epoxy Potting Compound DP270.

I purchase from McMaster-Carr (Midwest pickup window is 2 miles from house).
This is what I have used, since it is rated for -65° to 350° F and safe with
copper (potting electronics,

It's worth noting that the HP5370A has a doubler on the reference
input. It will accept either 5

Hi,
I strongly recommend the HP AN200 series of application notes. Having
those alongside Enricos slides is a good start for those new in the field.
There is one variant of averaging which is used in the HP5328A/B
counters that is described there that is not covered in Enrico Rubiolas
Gerhard,
May I have a copy of the Gerbers for the Doubler-Distribution amp? I started
designing a PCB for the board myself, but if you could send me a copy of your
files, surely would save me a ton of time and work.
Thanks for your willingness to share your work.

The interesting source you referred to contained a slide deck which
turned out to be a gold mine for a novice like me.

This should be on leapsecond
Many thanks

Hi,

You seem to have gone to extraordinary lengths to trap out each unwanted
product, yet the final spectrum shows only -50dBc products. That seems a
poor return for that effort in filter design.
I made a 5MHz doubler plus distribution for my HP5061. You can see the
design at
Thank you Gerhard. Great project!

Let’s start with the HP/Symmetricom 58503A/59551A manual (leapsecond.com)
http://www.leapsecond.com/museum/hp59551a/097-59551-02-iss-1.pdf
Use an appropriate Serial Cable for the SatStat program to access the 59551A.
The HP/Symmetricom 59551A uses SCPI commands for configuration.

Hello,
Probably Mupsil was a typo. Mapsil 213B is a silicone-based coating also
approved (at least by ESA) for space applications.
