Preface
xiv TDS 684A, TDS 744A, & TDS 784A User Manual
Conventions
In this manual, you will find various procedures which contain steps of
instructions for you to perform. To keep those instructions clear and consistent,
this manual uses the following conventions:
In procedures, names of front panel controls and menu labels appear in
boldface print.
���Names also appear in the same case (initial capitals or all uppercase) in the
manual as is used on the oscilloscope front panel and menus. Front panel names
are all upper case letters, for example, VERTICAL MENU and CH 1.
Instruction steps are numbered. The number is omitted if there is only one step.
When steps require that you make a sequence of selections using front panel
controls and menu buttons, an arrow ( ➞ ) marks each transition between a
front panel button and a menu, or between menus. Also, whether a name is a
main menu or side menu item is clearly indicated: Press VERTICAL
MENU ➞ Coupling (main) ➞ DC (side) ➞ Bandwidth (main) ➞
250 MHz (side).
Using the convention just described results in instructions that are graphically
intuitive and simplifies procedures. For example, the instruction just given
replaces these five steps:
1. Press the front panel button VERTICAL MENU.
2. Press the main-menu button Coupling.
3. Press the side-menu button DC.
4. Press the main-menu button Bandwidth.
5. Press the side-menu button 250 MHz.
Sometimes you may have to make a selection from a pop-up menu: Press
TRIGGER MENU ➞ Type (main) ➞ Edge (pop-up). In this example, you
repeatedly press the main menu button Type until Edge is highlighted in the
pop-up menu.
Default Model
This manual documents the TDS 684A, TDS 744A, and TDS 784A Digitizing
Oscilloscopes. However, the TDS 684A display screen appears as the default
screen wherever a display screen is illustrated in this manual. Also, this manual
uses the name “TDS 700A” when providing information common to both the
TDS 744A and TDS 784A model oscilloscopes.
