Set to zero
Under the “HORIZONTAL” menu, the SET TO ZERO button sets the horizontal position
(controlled by the horizontal position knob) to zero (center vertical axis), thus centering the
signal horizontally.
Help
The oscilloscope has a Help system with topics that cover all the features of the oscilloscope.
You can use the Help system to display several kinds of information: 1) general information
about understanding and using the oscilloscope, 2) information about specific menus and
controls, and 3) device about problems you may face while using an oscilloscope (e.g., reducing
noise). Pushing the HELP button (near top right) will activate a softkey menu as well as
context-sensitive information. The particular softkey options are <Show Topic>, <Index>,
<Help on Help>, <Back>, and <Exit>. The Help system provides three ways for you to find the
information you need: Context-Sensitive, Hyperlinks, and an Index.
a)
Context-Sensitive:
The oscilloscope displays information about the last menu displayed on
the screen when you push the HELP button. The HELP SCROLL LED lights under the
Position knob in the “HORIZONTAL” menu to indicate the alternative function of the knob.
If the topic uses more than one page, turn the knob to move from page to page within the
topic.
b)
Hyperlinks:
Most of the help topics contain phrases marked with angle brackets, such as
<Autoset>. These are links to other topics. Turn the Help Scroll Position knob to move the
highlight from one link to another. Push the <Show Topic> softkey button to display the
topic corresponding to the highlighted link. Push the <Back> softkey button to return to the
previous topic.
c)
Index:
Push the <Index> softkey button. This brings up an alphabetical list of topics on the
screen and activates a softkey menu whose options are <Show Topic>, <Page Up>, <Page
Down>, <Back>, and <Exit>. Push the <Page Up> or <Page Down> softkeys until you find
the index page that contains the topic you want to view. Then, turn the Help Scroll Position
knob to highlight a help topic and push the <Show Topic> softkey to display the topic.
Note: Push the <Exit> softkey button or any “Menus” button to return to displaying waveforms.
Run/Stop
Push the RUN/STOP button when you want the oscilloscope to continuously acquire waveforms
(default mode). Push the button again to stop data acquisition.
Single Sequence
Push the SINGLE SEQ button when you want the oscilloscope to acquire a single waveform and
then stop. Each time you push the SINGLE SEQ button, the oscilloscope begins to acquire
another waveform. After the oscilloscope detects a trigger, it completes the acquisition and
stops.
Horizontal Menu
Under the “HORIZONTAL” menu, the HORIZ MENU button activates a softkey menu that
allows access to several other means of focusing on a specific section of a waveform. Its options
are listed in Table 1.
