Overview

The topics below will help you understand how to use and get the best measurements from your oscilloscope.

Topics

Acquiring an Analog Signal

Learn about acquiring an analog signal, including topics such as bandwidth, amplitude error, rise time, sample rate, the Nyquist Sampling Theorem, aliasing, and resolution.

 

Analog Sample Quality

Learn about sensitivity, accuracy, precision, and noise in order to understand and improve your measurement sample quality.

 

Record Length, Vertical Range and Offset, and Input Coupling

Learn about the front end and memory settings of your oscilloscope to get the right data.

 

Oscilloscope Triggering
