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 con-
nected to earth ground. Before making connec-
tions 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 documenta-
tion for further ratings information before mak-
ing 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 P80318 High Performance 100 Ohm
Differential Impedance Hand Probe provides
users a differential hand probe with adjustable
spacing tips, EOS/ESD protection (with the
Tektronix 80A02 EOS/ESD Protection Module),
and a unique double spring mechanism that
provides physical feedback to optimize probing
contact pressure. The probe is suitable for
probing differential runs on circuit boards, IC
package pins, and other devices that have a
0.5 mm to 4 mm pitch.
The P80318 probe is 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).

Connector Care
Use extra care when attaching or removing the
cable SMA connectors from the probe. 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, tighten the SMA connectors to
56 N-cm (5 in-lb) with a torque wrench.

Probing Guidelines
H
The P80318 uses a unique double spring
mechanism that provides physical feedback
to optimize probing contact pressure. When
applying pressure after the initial contact to
the DUT, the first spring engages and the
probe tips retract with the first spring pres-
sure. As you apply more pressure, the second
spring engages, increasing the probe com-
pression resistance. This sudden increase in
stiffness is the correct operation zone. In-
