Oscilloscope newbie question - 2007-05-18 08:35:00

Hello,

At the bottom of the screen on my FLUKE PM3082 scope a have :
Ch1  1.00 V=   MTB 10us    ch1f .

Does the 1.00 V= means that every square along grid Y axis corresponds
to 1 V?

Thanks.

Dusan

Easy way to find out is to hook your probe to the calibrator, which
has a 600mVpp output.

Yes. But if you use a common 10:1 probe, and the scope doesn't know
it, that will become 10 volts/cm.

yes how ever, I don't think that scope has a 10:1 selection for the 
input if you're using a 10:1 mode probe.. in this case, each grid
block vertically would mean 10 times actual reading in voltage..
i could be wrong about the scope sensing the 10:1 probe being how ever.

Some TI scopes I've used did that, but they had special connectors.

Every other scope I've used apparently assumes that the operator knows
what he/she is doing.
