In addition to manuals, we should start to preserve the (EP)ROM
contents of these instruments, early generation EPROMS are reaching
end of life in a lot of systems.

I don't need to draw you a picture.
The ad claims it's a derivative of the HP 8920B, and it looks like it.

You are dreaming if you think DOD won't deactivate Galileo if they need
to.

There is a lot of commonality between the various 892x test sets. When I get
some time, I'll ping my buddy that was sales manager for the line at (HP)Agilent
Spokane division. I know we've talked some about it in the past, but don't
remember enough details to make any binding comments!

It could use more submissions, there are MANY more manuals than ROM images.
I will put the HP 5370A ROMs there soon.

Philip,
I think this sounds pretty reasonable, here's my 2-cents worth.
I think calibration should be part of delivering the clock. You can
imagine a designer developing elaborate models for the timebase and you
don't want to stifle creativity here. I think calibration is part of

Well things are pretty high right now. Here's how I got there:

Maybe quasi-simultaneously is adequate, using a switch to sample the 3 pairs

The HP59307A can be used for that under GPIB control.
I would think the main reason for doing it simultaneously is so that

Hi!
Just heard this and here is some details:

Looks like it just became likelier that we will have those Galileo birds.

In my experience watches come from the factory adjusted to gain about 5
seconds a month. The ones I have owned over the years seemed to be fairly
stable in that. I have always wished there was a way for someone who is not

A number of people have asked for more details on IEEE Spectrum's digital
clock competition, so we've formulated the following list. Throughout, the
idea is to build a clock that an ordinary person would want to use, in an

With a little work you might be able to precisely calculate the

What's the aging like for watch crystals?
What type of cut to watch crystals use? Are there any generalizations about

So use a gate array to implement a multichannel time stamp device.
FPGA development boards are readily available and some people consider the
price within range.
Would digital inputs be good enough? Suppose you feed several 10 MHz signals
into a FPGA and program it so each input signal
