These appear to be ferrite chokes.
Value may not be overly important.
Usually used to pass DC and reduce RF on a line.

Sorry I couldn't be of much
help, Keith.? Say, now I'm curious, what kind of components do
those E reference designators stand for?? The only time I've
seen that used was at Powerwave (now out of business) where
they were solder connection points for coaxial cables.? Are
those ferrite beads or something?? Enquiring minds want to
know!???? Jim
Hi
Keith,
?
This
is some pictures from my 34465A.

Thank you
for the insight and offer to assist.
The unit I
have has some burned components on the main PCB.
If I send
a list of the silkscreen component designations,
can you open one up and determine the
manufacturer part numbers?
I'm one of
those people who refuses to pay an outrageous
sum to replace the entire board when a few
dollars of replaceable components are the only
thing necessary to make the device functional,
again.
Just in
case you are able and willing to do this, I've
included the component designations:
I've also
attached pictures of the locations of these
components.
BTW: "No"
is an acceptable response.
Keith, that one is
probably too new to have a schematic
available.? Blame the suits at HPAK and
everywhere else for that.? BTW, we have
several of the 34461A DMMs around Raytheon
where I work, so if you have a question
about how to operate it, or is it supposed
to do this, or whatever, I'm happy to check
it out on one of the ones at work.? HTH.

Does
anyone know where I might obtain a
full schematic for the Agilent 34461A?
