P6209 4 GHz Probe Instruction Manual 1
Product Description
The Tektronix P6209 is a 4 GHz (probe only), 5X active FET probe
with 1 pF input capacitance. The probe is designed primarily for use
with sampling oscilloscopes, such as the CSA/TDS8000. The P6209
has a low input capacitance and high input resistance, which
minimize circuit loading over a wide bandwidth range.
The small profile and low-mass head of the P6209 make manual
probing of crowded circuits fast and easy. The accessory tips and
adapters enable the P6209 to be used on a wide variety of circuit
architectures.
The P6209 is powered through a TEKPROBE SMA interface
between the probe compensation box and the oscilloscope.
Options
The following options are available when ordering the P6209 probe:
HOption D1 -- Calibration Data
HOption C3 -- 3 years Calibration Service
HOption D3 -- 3 years Calibration Data
HOption R3 -- 3 years Extended Warranty

Features and Standard Accessories
The P6209 probe is provided with several features and accessories
designed to make probing and measurement a simpler task. Please
familiarize yourself with these items and their uses. For part number
information and quantities of standard and optional accessories, refer
to Replaceable Parts on page 55.
Probe tip
socket
Ground
socket
Stabilization
notch
Probe head assembly. The probe head is
designed for ease of use and high performance.
Its small size makes it easy to handle in tight
areas.
The probe tip socket is sized to easily press onto
0.025 inch pins for direct access. The ground
socket provides a short ground path for high
fidelity ground connections.
The stabilization notch permits you to use
adjacent pins to reduce stresses on the probe
and pins.
TEKPROBE SMA interface. The TEKPROBE
SMA interface provides a communication path
between the probe and the oscilloscope. Contact
pins provide power, offset, and probe characteris-
tic data transfer. See page 31 for more informa-
tion.
Color marker
bands
Color marker bands. Attach matching pairs of
the color marker bands onto the cable at the head
and compensation box of each probe. The marker
bands enable quick verification of which probe is
connected to which instrument channel.

Product Description
P6209 4 GHz Probe Instruction Manual 3
SureToe probe tip. The SureToe tip is a pointed
probe tip useful for probing in dense circuitry.
Attach the SureToe adapters the same way as
the push-in probe tips. Do not force the tip.Also,
be careful not to injure yourself with the sharp
probe tip. They can be used with any of the
socketed accessory leads.
Push-in probe tip
Push-in probe tip. Use the push-in probe tip
for general purpose probing by hand. The tip may
also be used as a temporary test point. See
page 19 for more information.
The push-in probe tip may also be used with the
other socketed leads and adapters.
Installing the push-in probe tip. Attach the
push-in probe tip by seating the tip into the probe
tip socket and pushing the tip in until it is seated.
Either end of the tip may be used.
Do not force the tip. Also, be careful not to injure
yourself with the sharp probe-tip. To remove the
tip, gently grab the tip with small pliers and pull
the tip out.
Right
angle
adapter
Right-angle adapter. Use the right-angle
adapter for low-profile probing of 0.025 inch
square pins.
The right-angle adapter allows the probe to lie flat
against a circuit board. This enables probing in
vertical circuits, such as computer or communica-
tions backplanes, or in tight areas, such as
between circuit cards.
The right-angle adapter can be used directly with
the probe head or attached to the Y-lead adapter
or ground leads.
The right-angle adapter is attached the same way
as the push-in probe tip and can be easily
removed by hand.

Product Description
4P6209 4 GHz Probe Instruction Manual
Y-lead
adapter
Y-lead adapter. Use the Y-lead adapter to
extend the physical reach of the probe and
ground when necessary. The Y-lead adapter
accepts any of the probe tips or adapters and
can be pushed directly onto 0.025 inch pins.
When selecting the grounding connection,
maintain as short a ground path as possible.
Refer to page 14 for more information.
Y-lead
adapter
To attach the Y-lead adapter, gently press the
lead pins into the probe head tip and ground
receptacles. Using the black lead for ground is
recommended.
Three-inch ground lead. Use the three-inch
ground lead for general probing. The socketed
end of the lead may be connected to any of the
probe tips and adapters or fitted onto 0.025 inch
pins.
To attach the ground lead, press and rotate the
lead pin connector into the ground socket on the
probe head. The lead may be removed by simply
pulling the pin out by hand.
When selecting the grounding connection,
maintain as short a ground path as possible.
Refer to page 14 for more information.

Product Description
P6209 4 GHz Probe Instruction Manual 5
Customizable
ground lead
Customizable ground lead.This ground lead
wire can be bent or cut shorter.
NOTE: To ease insertion into the ground socket
of the probe, cut the tip of this ground lead wire at
a 30 to 60 degree angle.
To maintain signal fidelity while probing, use as
short a ground path as possible. Refer to page 14
for more grounding information.
Pogo pin
Low-inductance ground pogo pin. Use the
low-inductance ground pogo pin to substantially
reduce ground lead inductance. Because the
pogo pin simply touches the ground reference,
you can easily move the probe to different points
on the circuit under test.
To attach, press the pogo pin into the probe head
ground socket.
When selecting the grounding connection,
maintain as short a ground path as possible.
Refer to page 14 for more information.
Signal-ground
adapter
Signal-ground adapter. The signal-ground
adapter is ideal for use with signal/ground pairs
on 0.100 inch header pins.
Attach the signal-ground adapter by gently
pressing it into the ground socket on the probe
head.
Be sure to use the stabilization notch whenever
possible to avoid slipping and damaging the
probe or circuitry under test.

Product Description
6P6209 4 GHz Probe Instruction Manual
KlipChip
Y-lead adapter
SMT KlipChip. Use the SMT KlipChip test clips
to access fragile, dense circuitry.
KlipChip test clips can be connected to the Y-lead
or three-inch ground leads. Simply press the lead
socket into the KlipChip handle.
The KlipChip body freely turns, allowing better
probe orientation. To reduce stress and provide a
lower profile on components being tested, the
flexible sleeve of the KlipChip bends up to a
35 degree angle.
When selecting the grounding connection,
maintain as short a ground path as possible.
Refer to page 14 for more information.
SMA adapter jack. Use the SMA adapter jack
with the SMT KlipChips to gain access to
calibration signals from SMA connectors on the
oscilloscope front panel.
Male SMA termination. Protect the probe input
circuitry by connecting the termination to the
probe input connector when the probe is not in
use.

Product Description
P6209 4 GHz Probe Instruction Manual 7
Optional Accessories
The following accessories are available for the probe. See the
Replaceable Parts List on page 55 for ordering information.
SureFoot probe tips. The SureFoot tip is an
integral probe tip and miniature guide that
enables fault-free probing of fine-pitch SMD
packages. Attach SureFoot adapters the same
way as the push-in probe tips. They can be used
with any of the socketed accessory leads.
The orange, 0.050 inch SureFoot tip is compatible
with 50 mil JEDEC packages such as SOIC,
PLCC, and CLCC.
The blue, 0.025 inch SureFoot tip is compatible
with 0.65 mm JEDEC and EIAJ packages.
The red, 0.5 mm SureFoot tip is compatible with
EIAJ packages.
SMK4 Micro KlipChip adapters. Use the
Micro KlipChip adapters to probe the leads on
integrated circuits that are surface-mounted.
SMA-to-probe tip adapter. Use the adapter to
connect the probe to SMA cables. The adapter
includes a 50-ohm SMA termination.
