Besides a 5370B and 5345A, I guess you could 'count' the one built into the
Tek 492AP analyzer.  All three are reflocked to a Trimble Thunderbolt.

Tek didn't officially offer signal-counting capability in the 492AP, but a
ROM upgrade and a few minutes alone with the front panel and a Dremel tool
took care of that little hangup.

My counter 'collection' is undoubtedly among the most humble on this list,
though, and I seldom use the 5370B for anything other than calibrating OCXOs
and the like.  The 492AP's counter is more convenient for most purposes,
because it inherits the dynamic range and frequency coverage of the (DC-21
GHz) spectrum analyzer hardware.

Then there's my classic Radio Shack 22-305 handheld, which was one of those
cases where Radio Shack screwed up and actually sold something good.  Years
after they went out of production, they still sell on eBay for close to
their original $79.95 price.

I wonder if Rick Karlquist could put you in touch with the Agilent people to
whom he donated the manuals that he mentioned awhile back.  They might be
able to use the contribution for their own public archive.
