2.14 Help System

This oscilloscope has a Help system with topics covering all of its features. You can use the Help
system to display several kinds of information:
 General information about understanding and using the oscilloscope, such as Using the Menu
System.
 Information about specific menus and controls, such as the Vertical Position Control.
 Advice to problems you may come across while using an oscilloscope, such as Reducing
Noise.
The Help system provides three methods for you to find the information you want:
context-sensitive, hyperlinks, and an index.
 Context-Sensitive
Push the HELP front-panel button and the oscilloscope displays information about the last menu
displayed on the screen. The HELP SCROLL LED lights beside the HORIZONTAL POSITION
knob indicate the alternative function of the knob. If a topic uses more than one page, turn the
HELP SCROLL knob to move from page to page within the topic.
 Hyperlinks
Most of the help topics contain phrases marked with angle brackets, such as <Autoset>. They are
links to other topics. Turn the HELP SCROLL knob to move the highlight from one link to another.
Push the Show Topic option button to display the topic corresponding to the highlighted link. Press
the Back option button to return to the previous topic.
 Index
Push the front-panel HELP button, and then press the Index option button. Push the Page Up or
Page Down option button until you find the index page which contains the topic you want to view.
Turn the HELP SCROLL knob to highlight a help topic. Press the Show Topic option button to
display the topic.
NOTE: Press the Exit option button or any menu button to remove the Help text from the
screen and return to displaying waveforms.
