Hi Group,
I contacted
Keithley about the omission and was told by John Sobola that all
schematics had been removed from downloadable manuals on Keithley's
site, as well as the instruction manuals for all current Keithley
products.
This is really disappointing because I used to think very highly of
Keithley instruments. I even owned some of their picoammeters (since
sold at a ham fest).
Keithley products are quite popular in the semiconductor test market
so I can only surmise that they have experienced the usual IP thief
that a number of semi companies have and therefore are suspecious of
people wanting maintenance info. OTOH, items this old are hardly a
threat to their well-being. Makes you wonder what planet they're
from.
Keithley isn't alone however. Krohn-Hite is also real quick to blow
off people who want maintenance documents for their old gear. I have
several of their 4000-series oscillators (nice signal sources BTW)
and phone calls and e-mails met with the usual brick wall blow-off.
I did the usual end-run around this by buying the manuals off E-Bay.
Ironically I've gotten great service & support from (of all people)
Leader Instruments. I have a few audio-range test instruments and
scopes and I've gotten full maintenance manuals from them just for
the asking (e-mailed to me in pdf format). Their gear is
*very* "fixable" - no ASICs or FPGAs; all discrete topology. Not in
the range of HP/Agilent or Tektronix but fun little toys just the
same.
