dumb question function generator i have a new scope and i thought i d save a few bucks by buying one with a function generator built in after having it awhile i noticed two things about the function generator for one there seems to be a bias even when the pull offset is pushed in that is i have to pull that know and adjust it to get a signal sans some random mv bias the other really annoying thing is that the damn output won t go below about v p p i am a student you may have guessed from my previous posts and i often have to measure the input impedances of various circuits i build many of the circuits have maximum input signals of way less than mv amplitude and most have input impedances in the s of kohm range the thing is in order to use my function generator i have to divide the voltage to some thing reasonable then of course to measurethe input impedance of my circuit i am going to have to throw in another resistor in series with the ohm output of the generator i could just ignore it but now with this little divider there i have to figure that in it s kind of a pain in the ass is there any way i could make myself a little box that could solve this little problem the box would tkae the function generator input lower the voltage and give an output impedance that is some low unchanging number i would want to lower the voltage by a factor of one hundred or so i could just build a little buffer amp but i d like to have this box not be active any quick ideas the scope s not broken for other reasons i had sent it to the shop to get repaired and they replaced it the function generator was the same way on that one too please help as i am feeling very stupid today dave dgj y virginia edu
