The Autonerdz DSO

Sample Rate Calculator

For a complete understanding of this, we recommend you purchase

Your own copy of this calculator is included.

For a short basic tutorial movie on the calculator and its use, view

Input the three values and press the calculate button.

You may choose whatever units you wish from the drop down menus.

The above Java Applet illustrates the relationship between signal frequency and sample rate.

You can see for yourself why sample rate is so important.

Note how the signal distorts and aliases when there is not enough sample rate for the signal frequency.

This is a demonstration of the Nyquist Limit.

You must sample a signal least 2x signal frequency or aliasing will occur.

A DSO without adequate sample rate will do exactly the same thing as shown here.

Not Good.

True sample rate is the single most important thing to consider when choosing a DSO.

Viewing requires a real version of Java. The primitive and crippled version that comes in Windows does not work.

If you just see a blank box, you need to install Java,

You can get it free here:

You should get it anyway. You need it for lots of different web content.
