Hi All,
Been lurking here for a while, some neat traffic going around. I'm
thinking this may be a question for this list...
I'm wondering if there are any ways to compare two frequencies and
tell if one is lower or higher than the other, at a very high rate of
speed with a digital output. I
OK, you've described what you think of as the solution to your problem, but
what actually is your problem? In other words what is your objective.
Are we looking at something like a phased array radar here? If so there is
probably quite a bit of stuff out there that isn't classifed by now as
There are phase detectors available that can easily run at 50 MHz.
The output signal contains the information you want, but you have to
filter it and decode it according to the response time needed.

If TAI is a paper clock, what else should be used if a strictly monotone

Do you have any specific application in mind?
If you need an SI seconds rated scale, then you need something based on
TAI. GPS time has a TAI second rate
Hi
Without knowing what you are doing, and the source of the unknown signal,
this is difficult to address. Here it goes anyway:
If the unknown is a free running source, then it has both a frequency (or
phase) modulation and a static phase offset. In other words, it can be on
the same frequency
Hi
The real question is what's the date code on the unit? If the rev E part is
old enough to have the good thermometer chip in it - that's the one to get.

Hi
If you have a time source to work with, generating a different time scale is
just a math problem. In most cases it's not a very complex one (subtract 19
seconds and move on). If you don't have a time source, then generating any
time scale will be a challenge.
Given the low cost of computing

A friend has an observatory and needs very precise time. It turns out

manually move the scope to put the star on the cross hairs. Doing this

Well, if it's any help, on my rev E unit with the 'coarse' temperature chip,
there is a sticker on the top (near the power connector) with a bar code, a

could be a serial number and some other kind of rev designator
