Hello,
I received my oscilloscope yesterday -- a tek 465b/dm44. Pretty nice machine, and I'm cluing myself in on how to get the best use out of it. I understand that probes can attenuate the input signal. The probe I got is a P6006 10X. I did a trivial experiment measuring the voltage on an AA battery, which was ~ 1.3 volts (confirmed with simpson meter and dm44). I put this on the scope and when the volt/div illumination is on .1, it occupies ~ 1.3 grids, which I expected. What I don't understand is that a book says the volt/div must be divided by the attenuation factor to get the actual reading. Shouldn't I have to multiple the attenuation by volt/div? Otherwise, my battery voltage would be .13! It doesn't make sense the other way around.
Thanks! Mike
