Now that I have my new [30 year old] HP 3586 making measurements
over the GPIB bus I have a few questions.

Setting AVErage makes measurements take about three seconds.
Is there a way to control the number of samples averaged?

How difficult is it to open up the 3586 to replace the input connector
with a BNC connector?

Is there a way to update and/or hack the firmware? Is source code
available?

It was reasonably easy to get to the input connector to replace it. I haven't
seen the firmware source code but would be interested if it became available to
play with. Some HP instruments used proprietary CPUs (or "nanoprocessors")
which might be tricky to play with due to their instruction set not being published.

I did install a bnc connector for input - pain - it took a few hours. Save
yourself a lot of grief and purchase a Canare bcj-vwp bnc adapter from
Markertech or others. Works fine.
