Notice for Trigger Function
xiv
This manual uses certain conventions that you should become familiar with.
Some sections of the manual contain procedures for you to perform. To keep
those instructions clear and consistent, this manual uses the following conven-
tions:
H Names of front panel controls and menus appear in the same case (initial
capitals, all uppercase, etc.) in the manual as is used on the analyzer front
panel and menus. Front panel names are all upper-case letters; for example,
SPAN, TRIG, and SELECT.
H Instruction steps are numbered unless there is only one step.
Throughout this manual, any replaceable component, assembly, or part of the
analyzer is referred to generically as a module. In general, a module is an
assembly (like a circuit board), rather than a component (like a resistor or an
integrated circuit). Sometimes a single component is a module; for example, the
chassis of the analyzer is a module.
Symbols and terms related to safety appear in the Safety Summary near the
beginning of this manual.
The trigger functions vary according to the product serial numbers due to the
different hardware as follows (the serial number is labeled on the bottom-right
corner of the rear panel):
H S/N B020000 and above
H S/N below B020000 and J300100 and above
In this manual, trigger-related descriptions and specifications are marked with
the appropriate serial number if necessary.
