HP made a
couple of other devices that I don't own and could never see
the point of. One was the 'signature analyser' which will tell you if
a logic signal differes from the correct version (well, provided you
have a 'correct version' to also test) but won't tell you _how_ it
differs. So actually finding the fault doesn't seem to be any easier.
I remember reading about signature analysis in the HP Journal. It
looked like a promising technology--not for the lone self-employed
technician, but for the field engineer who saw the same equipment day
in and day out.
