IIRC the internal transfer price was $400.
The whole "business model" of being a captive supplier
was extremely messy, including the calculation of
internal transfer price. For T instruments for
internal consumption, they abandoned "transfer at
cost" decades ago.
This was probably one of the
The Prologix is very easy to use . I use it with Labview ($ 50.00 Home
edition) and have several vi's.
I have interfaced it with HP 3325A, HP 3405A , HP 3478A , WK 2400, XL
Microwave 3401 and several others.
You can use Termite(free) or GPIB Configurator ( free) to sent one liners

C12 and C15 on the support board are for peaking the multiplier/amplifier
for the external standard input. The unit accepts 1MHz, 5MHz or 10MHz for
the external reference frequency. The capacitors tune the external input to
10MHz for the counter to use as the reference.

Hi
The “most often mentioned” run rate was “about 800 a month". It was never at
all clear
if that also came out to 10,000 a year or not. ( = how often did they hit that
rate).
If you wanted to buy one piece, I believe the price was $800. At that price,
even 800 a
month would be pretty good

Luiz,
Found some more info on replenishing the Hydrogen in the Kvarz CH1-76 and
CH1-75.
Anders had the procedure pretty close for a fully charged canister from
the vendor.
However recharging the original is a bit more challenging!
Use care and protective gear from the high and low temperatures
Folks:
I’ve been doing a lot of SW work using the U-blox ZED-F9P chip over the past
few months. Being a SW guy, I try to minimize the amount of breadboarding and
HW integration I have to do.
For several months most of my work has been using the SimpleRTK2B board from

Hi,
At operating temperature the lamp, filter cell (if used) and the
resonance cell only have gaseous Rubidium in them.
Only exception is early designs that have a "stem" on the resonance cell
that exits the cavity.
There is a small amount of liquid Rubidium in the stem and in the 5065A a
Surface tension keeps the liquid Rb in place in the short term.
In the long term, the Rb has to be designed to have place
where the Rb was concentrated to be at the lowest temperature.
In the HP10816, this place was the "tip-off" for the cell.
We tried to heat sink the tip-off to cool it off.
It seems to me that the basic operation of the Rb cell and/or the filter
cell
and lamp must all involve the presence of some liquid Rb at normal
operating temperatures. Otherwise, temperature regulation would not
be a viable means of controlling the Rb concentration on the vapor mix.
If I'm

With a multiplexed display you should be able to do it all with one
processor.

You really can't properly monitor any stratum-2 sources you have

US operators are planning to shut down their CDMA networks. See for example

I wouldn't be surprised to see this date get pushed back though.
