Manual Conventions
This manual uses certain conventions that you should become familiar with
before attempting service.
Throughout this manual, the term module refers to a TLA 700 Series Logic
Analyzer, DSO, or Benchtop Controller that mounts inside a TLA 700 Series
Color Benchtop Chassis. A module is composed of circuit cards, replaceable
parts, interconnecting cables, and a user-accessible front panel.
Benchtop Controller. In this manual the term “benchtop controller” refers to the
TLA 711 Color Benchtop Controller module.
Benchtop Chassis. In this manual the term “benchtop chassis” refers to the
TLA 711 Color Benchtop Chassis that the TLA 711 Color Benchtop Controller
module plugs into.
Benchtop Mainframe. In this manual the term “benchtop mainframe” refers to the
combination of the TLA 711 Color Benchtop Controller and the TLA 711 Color
Benchtop Chassis. When the benchtop controller is mounted in the benchtop
chassis the resultant piece of equipment is referred to as the benchtop mainframe.
This manual refers to any field-replaceable assembly or mechanical part
specifically by its name or generically as a replaceable part. In general, a (field)
replaceable part is any assembly, such as the hard disk drive, or a mechanical
part, such as the I/O port connectors, that is listed in the replaceable parts list of
Chapter 10. Also, see Strategy for Servicing on page xiii.
Symbols and terms related to safety appear in the General Safety Summary found
at the beginning of this manual.
