$35 would be great, but I suspect it may be a good bit less than the
current owner has invested. But I can't, myself, see paying a bit more
than double what I invested in my Z3816A. Might be ok for some, but
seems way pricey vs the current available Thunderbolts unless there is
some major advantage that I don't know about. Lost the link, was it
rs422 control port? I don't see that as an advantage. The 3816 talks to
standard serial without modification.
I think what you have is pretty good. Not all that much legacy vs most
of my favorite stuff. Can't see why it would wear out soon. No Cs or Rb.
His listing does short the Z3816A by a few ports in the comparison.
There are 4 1 PPS ports, not two and there are also 4 19.6608 MHz ports.
If you don't have use for the 19.6 ports, I did find a way to convert
mine to make them 10 MHz square wave outputs. See:
http://www.xertech.net/Projects/Z3816/3816_mod.html
This gives the 3816 these outputs: standard 2 10 MHz sine, 4 1 PPS pulse
and then 4 10 MHz square wave.
For those who can afford, happy shopping. For any who have Z3816A's
and want more 10 MHz, I hope my mod works for you.
