How the Oscilloscope Works

Choosing Plug-ins

Choosing Plug-ins

The accuracy of your measurement results depends on the configuration of
your oscilloscope system. Part of the configuration is knowing how to set up
the various menus that are described in this book for your application. The
rest of the configuration is comprised of choosing the plug-ins and probes to
use for the measurement. There are several plug-ins available for the
oscilloscopes, and you need to pick the plug-in that best matches your
application.
When picking a plug-in, you also need to think about the rise time of the
oscilloscope compared to the rise time of the signal you are measuring.
The oscilloscope rise time is about:
0.35
Scope Rise Time =
Bandwidth
To obtain a rise time measurement accuracy of 5 percent, the rise time of the
oscilloscope should be one-third the rise time of the signal you are measuring.
To obtain a rise time measurement accuracy of 1 percent, the rise time of the
oscilloscope should be one-seventh the rise time of the signal you are
measuring.
The measured rise time is about:
√  
Measured Rise Time =
2 + Scope Rise Time 2
Actual Rise Time
