I worked in the HP Santa Clara Division frequency counter
section at the time of the development of the 53132A series, which had
the internal code name of "Major League Baseball". IIRC, the external
reference circuit in it was designed by a couple of
engineers who had no background in time nuttery and
did a mediocre job. Someone else commented on a problem
with it not wanting to measure 10 MHz correctly. I
never heard of that before, but it would not surprise
me, because the main measurement engine was designed
by a very excellent FPGA engineer without an extensive
background in time nuttery. The problem mentioned might
have been too subtle.
The 53132 has many good points but is not perfect.

It does not have any options.
It is from a place that sells "selected" E-waste. I was in a water damaged
box, and was from a DHL freight insurance sale. It's been in the box until
a couple weeks ago.
Anyway, until now I've not followed the conversation on the issues with
using the External Reference, which I would like to do. But don't see if
there
were any conclusions or anything that could be done other then the issues
where fixed in the "B" version.
Is there a problem and a 'fix' that I missed searching the archives ?
