How are you planning to verify that the crap you buy on ebay
is giving a valid output?
Anything without a recent NIST-traceable certificate
is only adding more variables to your situation.

If you have doubts about the accuracy of your scope,
take it to a metrology lab
for calibration with NIST-traceable standards.

Hey Jeff, can always count on you shooting straight, narrow and
succinct.

i do not need traceable calibration

as an amateur hobbyist, i just want to put the new scope through
wide range of measurements to see if there are any gross problems
.... if scope measures close on varied ranges then i have peace of
mind that scope is in fair working order.

so if i test an unknown scope with unknown signal generator and
they both come close in agreement i think i can be
**statistically** comfortable that both are in close enough for
hobby work condition.
if they do not agree well then i can use some other means to test
signal from generator then go from there.

this is part of the hobby i have 2 x 2236 for scopes from the
bay.... a scope and parts spare for under $90 (*delivered*) one
appears to be functioning well, the other maybe working well and
that suits my hobby budget

calibration is what... $150 ? thats more than the two and
shipping combined

thanks again for the response, thoughts and straight shooting
