Preface
This posts seeks to summarize the general rules of the oscilloscope from the numerous brands and models. After read this posts, I hope readers can handle the most digital oscilloscope.
The scope of this post does not cover large desktop oscilloscope. This post is divided into two parts: basic parts and advanced parts. By learning the basics, you will have a basic understanding of the using of oscilloscopes, and the majority of common signals to debugging, display, and some quick automatic measurements. After learning the advanced parts, the use of the oscilloscope will have a more profound understanding. For the signal can debugging, preservation, analysis etc.
Basic Parts
Chapter 1 Types of oscilloscope
The common oscilloscopes has desktop oscilloscopes (this post does not cover the use of methods), portable oscilloscopes, handheld oscilloscopes and tablet oscilloscopes.
1)Desktop oscilloscope

2)Portable oscilloscope

3)Handheld Oscilloscope

4)Tablet Oscilloscope
As the name suggests, tablet oscilloscope is no buttons and knobs, using full touch operation.

Chapter 4 Probe Compensation Calibration
The normal probe compensation calibration outputs a standard square wave signal. As below shows:

The following two cases means compensation probe is not correct, you will need to use the "adjustment bar" to adjust the compensation capacitor on the probe.

Overcompensation

Undercompensation
Using the Philips head screwdriver to insert the hole near the BNC top, turn the probe compensation adjustment screw until the square wave appears to be free of distortion.

The probe compensation capacitor is on the BNC port, there is also other probes set it at another port, as below figure shows:

Check the probe when you
1. use the oscilloscope first time
2. use a new probe
3. no use oscilloscope for a long time.
