Front-Panel Overview
Before you make measurements using the Agilent 54620-series and
54640-series Oscilloscopes, you must first set up the instrument using
front-panel controls. Then, make the measurement and read the display
results.
These oscilloscopes operate much like an analog scope, but they can do
much more. Spending a few minutes to learn some of these capabilities
will take you a long way toward more productive troubleshooting. The
“MegaZoom Concepts and Oscilloscope Operation” chapter has more
detail on the things to consider while operating your oscilloscope.
The keys on the front panel bring up softkey menus on the display that
allow access to oscilloscope features. Many softkeys use the Entry
knob to select values.
Throughout this book, the front-panel keys and softkeys are denoted by
a change in the text type. For example, the
Cursors key is on the front
panel and the
Normal softkey appears at the bottom of the display directly
above its corresponding key. Other softkey graphic conventions used
on the oscilloscope and throughout this guide are shown in the “Getting
started using the oscilloscope interface” topic in chapter 1.
