[time-nuts] HG 414A Rubidium

[Bob Camp]

Hi

The whole counter thing has been run around in a thread back a month to
three months ago. It's in the archives.

Bottom line - if you want a cool one, it's got parts in it that are tough to
work with in a basement setting. If you stick with easy to solder parts,
it's not as cheap / fast / cool. For reasonable performance, price gets
above that of a "who knows if it works" 5370 on the auction sites. Even the
53181 it's self can be had fairly cheap if you spend a while (months)
shopping for one. The last 53181 I bought was under $500.

Yeah, I would be one of the bidders for this little toy
ifn it was available for purchase here.

I think that someone needs to take up the flag to begin
a group project to scratch design a home buildable
reciprocal counter. The project would teach a lot and
would result in quite a few folks on this site acquiring
significantly improved counting performance. Something
on the order of a 53181A would be very nice. The finished
module would be made of a processor, an FPGA,
and some peripheral bits. The manual for the 5345A
exposes quite a bit of theory and some this circuitry
might be directly adaptable to an FPGA.

I have been watching Scottys Spectrum Analyzer Group
for years and this SA / VGA is becoming an amazing
piece of equipment based on small (or not so small)
contributions of many of the participants.

Any thoughts?

Greg
