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.
To avoid fire or personal injury
Ground the product.
This product is indirectly
grounded through the grounding conductor of the
mainframe power cord. To avoid electric shock,
the grounding conductor must be connected to
earth ground. Before making connections to the
input or output terminals of the product, ensure
that the product is properly grounded.
Observe all terminal ratings.
To avoid fire or shock
hazard, observe all ratings and markings on the
product. Consult the host instrument documenta-
tion for further ratings information before making
connections to the host instrument.
Do not apply a potential to any terminal, including
the common terminal, that exceeds the maximum
rating of that terminal.
Do not operate with suspected failures.
suspect there is damage to this product, have it
inspected by qualified service personnel.
Do not operate in wet/damp conditions.
Do not operate in an explosive atmosphere.
Keep product surfaces clean and dry.

environmental impact of the product.
Product End-of-Life Handling
Observe the following guidelines when
recycling an instrument or component:
Equipment Recycling. This product complies with
the European Union's requirements according to
Directive 2002/96/EC on waste electrical and
electronic equipment (WEEE). For information
about recycling options, check the Support/Ser-
vice section of the Tektronix Web site (www.tek-

Restriction of Hazardous Substances
This product has been classified as Monitor-
ing and Control equipment, and is outside the
scope of the 2002/95/EC RoHS Directive.
This product is known to contain lead and
hexavalent chromium.
Product Description
The 80A02 EOS/ESD Protection Module protects
the sensitive input stage of instruments (like the
sampling bridge of electrical TDR sampling
modules) from damage due to electro-overstress
(EOS) and electrostatic discharge (ESD) from the
device under test (DUT).
When used with the P8018 TDR probe, the
80A02 achieves static protection using normal
probing procedures — no intentional user
intervention (such as stepping on a foot switch) is
required. This eliminates instrument damage due
to human error in coordinating probing with
control switching to achieve static protection.
Installing and Removing the Module
Refer to the host instrument documentation for
proper installation and removal of modules.

Connector Care
Use extra care when attaching or removing SMA
connectors. Turn only the nut, not the cable. Align
the connectors carefully before turning the nut.
Use light finger pressure to make this initial
connection. Then tighten the nut lightly with a
wrench. Ideally, the SMA connectors should be
tightened to 56 N-cm (5 in-lb) with a torque
wrench.
Operation
The 80A02 protection module passes the test
signal from the DUT to a sampling module,
providing EOS and ESD protection to the input of
the sampling module.
The FROM DUT connector of the protection
module is initially held disconnected from the
sampling module and terminated through a 50 Ω
termination installed on the TO TERM connector,
to remove EOS and ESD from the DUT. When
the module is engaged, (via the control input), the
signal is passed from the FROM DUT connector
to the TO SAMPLER connector, and on to the
sampling module.
No EOS or ESD protection is

provided if the TO TERM connector is not
terminated with the 50 Ω termination.
