And as Tom pointed out, to be confident that your e-10 oscillator has
not drifted beyond e-10, you will need some means of periodically
comparing it to a better standard (which could be GPS or WWV, or a
better local standard such as a cesium or hydrogen maser
source). This will require

I was thinking maybe something with an uncertainty of around 1e-9 or
1e-10. Are there simple quarts oscillators that are good enough for
that or is more equipment necessary?
Adam, your original post seemed to state a goal of having a small
and lower level time lab. Is
Every timelab needs a time interval counter. I'd say look for a HP 5334B
with option 010. I've picked up two from ebay for about USD100 each, and
that comes with a decent 18011. After that, watch your cash disappear as
you discover a need for faster/better/more accurate instruments, not to
mention
Adam:
It depends.
What are you trying to do?
How much accuracy is needed?
Do you mean just time, or some other metrics, too?

Hi
What kind of gear do you already have? I’d guess a computer. Can it be / is it
part of the time lab?
What sort of background do you have (is equipment repair something you do)?
How about building stuff from scratch? Do you have soldering gear etc?
What sort of budget do you have? Is $100,000
You can do a lot for $200 if you can build electronics yourself.
Decent GPS with PPS starts at under $20 on eBay. Same for surplus
10MHz oscillators. People have build usable counters for cheap
microprocessor development boards and software.But it all depends
on what you want to measure

I was wondering how expensive it would be to have even a small and lower
level time lab. What are some less expensive models of machinery i would
need, and how much maintenance is required?
Thanks, Adam
