Welcome
This is the User Manual for the TDS Family Digitizing Oscilloscopes .
The
Getting Started section familiarizes you with the operation of the digitizing
oscilloscope.
Operating Basics covers basic principles of the operation of the oscilloscope.
These articles help you understand why your instrument works the way it
does.
The
Reference section teaches you how to perform specific tasks. See
page 3-1 for a complete list of tasks covered in that section.
The
Appendices provide an options listing, an accessories listing, and other
useful information.
The following documents are related to the use or service of the digitizing
oscilloscope.
H The
TDS Family Digitizing Oscilloscopes Programmer Manual (Tektronix
part number 070–8709–01) describes using a computer to control the
digitizing oscilloscope through the GPIB interface.
H The
TDS Family Option 05 Video Trigger Instruction Manual (Tektronix
part number 070–8748–00) describes use of the video trigger option (for
TDS oscilloscopes equipped with that option only).
H The
TDS 520A, 524A, 540A, 544A, & 644A Reference (Tektronix part
number 070–8711–01) gives you a quick overview of how to operate your

In the Getting Started and Reference sections, you will find various proce-
dures which contain steps of instructions for you to perform. To keep those
instructions clear and consistent, this manual uses the following conventions:
H In procedures, names of front panel controls and menu labels appear in
boldface print.
H Names also appear in the same case (initial capitals, all uppercase, etc.)
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,
CH 1, etc.
H Instruction steps are numbered. The number is omitted if there is only
one step.
H 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) ➞Band-
width (main) ➞100 MHz (side).
Using the convention just described results in instructions that are graphi-
cally 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 100 MHz
H Sometimes you may have to make a selection from a popup menu: Press
TRIGGER MENU ➞Type (main) ➞Edge (popup). In this example, you
repeatedly press the main menu button Type until Edge is highlighted in
the pop-up menu.
