Digital and MSO Oscilloscope

After the Digital Multi Meter, the Oscilloscope is typically then next major piece of test equipment an electronic Hobbyist or professional should learn to use. A basic oscilloscope gives us the ability to look at a wave form in an amplitude verses time domain. This allows us to see the frequency (time) of the AC signal and it voltage (amplitude). We can see if our signal is clean or if it has noise in it. For digital signals it can show us if the voltages are at the correct levels for our logic signals and also show whether the digital signal is clean or noisy.
