Re: Oscilloscope arrived - black market sucks

Kreso,

Do you know HOW to use the oscilloscope?  I suggest you get a book on
oscilloscopes,  they can be very useful and you will learn what the various
sweep,  triggering, voltage buttons and knobs do and you can maximise the
use of your oscilloscope.
