Environmental Considerations

This section provides information about the
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/Ser­vice section of the Tektronix Web site (www.tek­tronix.com).

Restriction of Hazardous Substances

This product has been classified as Monitor­ing 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.

Using the Probe

Connector Care

Use extra care when attaching or removing the
cable from SMA connectors. Turn only the nut,
not the cable. When attaching 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.

Probing Technique

The probe tip and grounding clip are designed to
probe printed circuit boards (PCB) that
incorporate ground reference points next to the
signal measurement point. This is to allow the
probe tip to be inserted into a PCB through-hole
test point while the ground clip contacts the
ground reference point.

To achieve the specified bandwidth, the ground
clip must be trimmed to the shortest length
possible for probing the PCB. See Figure 2 for
proper probing technique and ground clip
trimming.

Safety Summary

To avoid potential hazards, use this product only
as specified.

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.

Connect and disconnect properly. Do not connect or

disconnect probes or test leads while they are
connected to a voltage source.

Observe all terminal ratings. To avoid fire or shock

hazard, observe all ratings and markings on the
product. Consult the host instrument documenta­tion 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. If you

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.

Product Description

The P8018 is a handheld passive probe with a
50 Ω input impedance. The P8018 comes standard
with a one meter SMA male-to-male cable
assembly that interfaces with an 80A02 EOS/ESD
Protection Module or other SMA connectable
input.

Figure 1: P8018 handheld TDR probe

The P8018 probe is especially designed to be used
with the Tektronix 80A02 EOS/ESD Protection
Module. Together, they protect sensitive
instrument-input stages, such as the sampling
bridge of Tektronix electrical sampling modules,
from electro-overstress (EOS) and electrostatic
discharge (ESD) damage due to static charges
stored in the device under test (DUT).The P8018
probe can also be used as a stand-alone,
high-bandwidth probe that is usable with any
SMA connectable instrument.

The P8018 provides a unique pressure-actuating
probe tip that switches between DUT
static-discharging protective mode and
engaged-measurement mode.

These instructions describe the operation of the
P8018 probe connected to a Tektronix 80A02
protection module which is then connected to an
instrument to be protected such as a Tektronix
80E04 or SD24 electrical TDR sampling module.
