I don't mean to insult you, but if you're new to scopes then you might not be aware that many have adjustable attenuation controls on X/Y inputs, via either or both an analogue control or a multi-position switch. It would be worth checking the scope's user manual for more information if you haven't already done so. Then again, maybe it is just poorly calibrated :)

so i scoped the pins on the 8048. pin 2 gave me a pretty healthy looking hf sine wave. pin 3 gave me a rather lumpier looking sine at about a thurd the amplitude. pin 20 gave me nothing at all.... no offset ... and pin 40 gave me a healthy dc only offset.
i could hazard a guess at the voltages but channels 1 and 2 on my scope dont agree at all and also dont agree with my dmm when measuring a AA battery... (throws hands up)
