This kind of problem is almost always the electrolytic filter capacitors
in the power supply shorting. Sometimes they take the diodes with them.
the repair is easy. I often preemptively replace all the power supply
electrolytics in old devices.

That link has been dead for all the years I've visited their site. Given the

Henk,
Thanks very much! I knew that someone would have a copy.
Chuck, I always check the wayback machine. I just sometimes forget to
mention that. :) The wayback machine is good, but there are many
technical issues and administrative decisions that make it more
frustrating than useful.

Hi Steven,
You can contact me off-line about this if you want more information.
Being someone with plenty of cesium clocks I looked into his claims in the late
90's. His cables and electronics were not at all temperature compensated. It's
a simple mistake we all make at one point or another in

Maybe if the cables were burried sufficiently deep, there would be no
short term changes of temperature, since the temperature underground
is more contant than on the surface of the earth.
If the cables are buried on the order of 1 m deep, in touch with the
ground, temperature effects are drastically cut, without controllers,
etc. Surface temp changes are very attenuated.

The most common approach is to *assume* that the two devices are

There was a point in time where HP made a *lot* of the Cs standards out there.

The 10544 was a BT cut based oscillator. When they went to the SC in the 10811,
making it from natural quartz was pretty much not an option. HP bought blanks
from several suppliers. I suspect they each switched to synthetic at a
different point.

The OCXO in most Rb's isn't all that great. They are after good ADEV, but
tempco and aging aren't terribly important.

What are you trying to do? If you are simply trying to run NTP, there are a lot
of options. If you want more than that, then your options narrow down a bit.

Dear All:
I just got a Z3815A GPSDOS, now it working well, but I have few questions:
1, Why my Z3815A will do survey everytime at power on? Even its finished survey
100%.
2, Why its date is 1994 Jun 11? But time is correct.
3, What's type of antenna connector in back panel?
Thanks!

Sorry I forgot a qeustion about EFC, last night when I power on my Z3815A, it
had a alarm message is EFC limit, I use follow command to watch EFC value:

Yes, in many of the more recent Rb standards you're lucky if the crystal
is ovenized at all. But are you sure that they're after good ADEV? I
get the impression that the only thing they're interested in is low
drift for the unit (e.g. for holdover purposes) since they're intended
