How to Read an Oscilloscope

25 08 2011

Here is a quick tutorial on how to read an oscilloscope.

Voltage increases as you go up the screen.

Time passes from left to right.

The three numbers circled below are the keys.

In this example:

1V  means the distance between each gridline bottom to top  represents 1 volt.

500µs means the distance between each gridline left to right represents 500 microseconds.

2.160V is the voltage between two lines I manually adjust. This is called a cursor.

The small cross circled on the lower left indicates zero volts.

Those are the basics of reading a ‘scope.
