Picked up an HP-1725A at Xenia this year with a couple of known defects including a non-functional Time Interval Multimeter option. Have the scope working for the most part.
I have so far not found anything on the operation of the Time Interval Multimeter. Which is odd as most HP stuff is well covered online. Maybe I'm just not typing the correct search terms.
Can anyone help?
the multimeter option is covered by a separate service manual, but the
time interval multimeter
is a standard HP-3476A (or B, afair) with a separate switch to read
either its inputs or the time interval dependent voltage present on
all the 17xx scopes (always, as far as I remember).
So you could use the 3476 service manual and schematics to fix the
multimeter. With a slide switch in the "time interval" position, it
reads the 1725's time interval output, which is covered
by the scope manual.
