Handle Components Carefully. Do not slide sensitive
components over any surface. Do not touch exposed
connector pins. Handle sensitive components as little as
possible.
Transport and Store Carefully . Transport and store sensitive
components in a static-protected bag or container.
Manual Storage
The oscilloscope front cover has a convenient place to
store this manual.
Safety Summary
To avoid potential hazards, use this product only as
specified. While using this product, you may need to
access other parts of the system. Read the General Safety
Summary in other system manuals for warnings and
cautions related to operating the system.
Preventing Electrostatic Damage
CAUTION. Electrostatic discharge (ESD) can
damage components in the oscilloscope and its
accessories. To prevent ESD, observe these
precautions when directed to do so.
Use a Ground Strap. W ear a grounded antistatic wrist strap
to discharge the static voltage from your body while
installing or removing sensitive components.
Use a Safe Work Area. Do not use any devices capable of
generating or holding a static charge in the work area
where you install or remove sensitive components.
Avoid handling sensitive components in areas that have a
floor or benchtop surface capable of generating a static
charge.

Installing the Application Module
Please refer to the TDS3000 & TDS3000B Series
Application Module Installation Manual for information
on installing your application module.
Advanced Trigger Features
The TDS3TRG Advanced Trigger application module
adds logic and pulse triggering capabilities to your
TDS3000 series oscilloscope. This section provides an
overview of these new features.
Logic Trigger Features
Logic triggering triggers the oscilloscope when two
signals meet a Boolean logic condition. The advanced
trigger module provides pattern and state logic trigger
modes.
Pattern Trigger . Pattern triggering triggers the oscilloscope
when two signals become logically true or false. Basically, the pattern-triggering feature triggers the oscilloscope
from the output of a two-input AND, OR, NAND, or
NOR logic gate. You can specify time constraints and
signal threshold levels as part of the triggering condition.
This trigger is useful for digital logic troubleshooting.

State Trigger. State triggering triggers the oscilloscope
7
Slew Rate. Slew-rate triggering triggers the oscilloscope
when a signal’s slew rate (rise or fall time) is less than,
greater than, equal to, or not equal to a specified slew
rate. This trigger is useful for troubleshooting digital bus
transceivers, transmission lines, and op-amp circuits.
Accessing Advanced Triggering
1. Push the Trigger MENU button to display the Trigger
screen buttons.
2. Push the Type bottom screen button to display the
trigger type pop-up menu.
3. Push the Type bottom screen button to select Logic or
Pulse triggering.
4. Push the Class screen button to select trigger class.
when a state signal is true or false at the time a clock
signal transition is true. This trigger is useful for troubleshooting digital logic synchronous state machines.
Pulse Trigger Features
Pulse triggering triggers the oscilloscope when a signal
meets a timing or threshold condition. The advanced
trigger module provides three pulse trigger modes: pulse
width, runt pulse, and slew rate.
Pulse Width. Pulse-width triggering triggers the oscillo-
scope when a signal pulse width is less than, greater
than, equal to, or not equal to a specified pulse width.
This trigger is useful for digital logic troubleshooting.
Runt Pulse. Runt-pulse triggering triggers the oscillo-
scope when a signal pulse is less than a specified threshold level. You can also specify runt pulse-width parameters. This trigger is useful for troubleshooting
bus-contention problems.
