There is a quite the knowledge of this and many other HP/Agilent
instruments on the Yahoo group "hp_agilent_equipment". That is not to
say there isn't here. But just more members since this is time-nuts
not T&M-nuts.
Including reference to at least one web site that has details on

Hi Gang,
Has anyone looked into working over the filters and detection
circuitry in the C model. I have not looked to see if that part is

I found some information on the 3586 by looking at
the service manual PDF. The processor is a Motorola 6800,
the same family I used in 1975 for Sidereal. According to

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 se
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
