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. Wear a grounded antistatic wrist strap
to discharge the static voltage from your body while
installing or removing sensitive components.
UseaSafeWorkArea.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.

3
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.

Conventions
The following conventions apply to all TDS3TMT
functions:
HYou can perform multiple waveform mask testing by
connecting signals to all oscilloscope input channels.
HWhile in Telecom Mask test mode, the AUTOSET
front-panel button automatically sets the oscilloscope
horizontal, vertical, and trigger parameters, and
positions the waveform in the selected mask.
HMask testing only works with live channels. It is
recommended that you turn off math and reference
waveforms while doing mask testing.
