I was actually going to suggest that it would be really nice to see a
comparison of the various time interval counters.

If I am not mistaken,  one I looked at had options to allow its use to
15:GHz, which might be nice for me as I do a lot of microwave stuff. But I
suspect such options are expensive and I would be better buying a microwave
frequency counter and a lower frequently TI counter.

I have an old HP microwave counter, but

* It doesn't have the GPIB option or any other options for that matter.
* It has a fault
* It is nowhere near as sensitive as a modern unit

So I can't really be bothered to try to fix it.
