Static vs. Moving wave in an Oscilloscope

[guilesar]

I have a basic question about using an oscilloscope... What's the difference between an oscilloscope displaying a static wave versus a moving wave? Is the difference in the type of scope you're using (digital vs. analog) or is it a setting on the scope itself? This would be used for visualizing a note played on a guitar.

Thanks in advance!

The "trigger" circuit on the 'scope is what allows you to get a stationary display of a repetitive waveform. The tutorials at Tektronix should help you to understand better how to work with oscilloscopes effectively and comfortaby:
