apart is fascinating and something I'd like to learn how it is done.
The VNA is a good comparison. I have a nice scalar nw but would like a VNA.
That's kinda my point about using rs232. Serial to USB, serial to Ethernet
adaptors will be available for a good long while.
Also why I like the idea of a standalone instrument that also has a pc
interface of some sort. Or a slot for a pc interface of whatever source I
want.
So how does o
I love those Hammond boxes until I have to pay the bill. The one for my n2pk
VNA was about $28.
But one of those as the primary enclosure with input boards and output boards
that plug into a main board would be feasable if a tad expensive.
Some modules lend themselves to plugins on a main boa

Greg,
I'm going to be in the area next month and might be able to pick some up and
redistribute them if that is of any assistance.
If I can end up with a clock somehow, I'd be interested in that too.

Of the 2 lc orgs I administer or am a member of, and the roughly 8 other lc
orgs I interact with on a regular basis, only one uses lc certified gps equip.
The others are all consumer grade or don't use gps.
However, a slew of filings and letters from the lc community might not be a bad
idea,
Sorry. Life critical. Fire, ems, law enforcement, aviation, etc.

I've not seen 110v fans in 'ultraquiet'.

James,
I used an old 1 u server case and it's accompanying power supply. The back
panel was already punched for a db9. All I had to do was drill some holes for
BNC output and sma for the antenna connector.
The big win was the 2x16 backlit LCD panel on the front which I hooked up to a
monitor
Another interesting measurement would be to use the timebase output and
external reference to compare the readings using the same timebase.
Or are you already using a gpsdo?

I have this problem as well. The issue is that the USB com port shows up as a
different number sometimes after a reboot and thus I must go in and manually
disable the 'mouse' again.
Quite annoying when trying to set up a system that just boots up and works.

That small hemispherical antenna could also have been 900mhz. I have one here @
home that is a combined gps/900mhz antenna from an ambulance tracking system.

Guess I'm an oddball, I have my choice of about a dozen wrist bourn time pieces
from the dresser.
Hardly the best, but my favourite is a euro spec tag heurer chrono.

My educated guess is that they expected to sell these to telcos, who
traditionally run everything in a central office on -48v and running off of ac
was an afterthought.
