Features and Accessories

The P5100 is a 100X, 2500 V (DC + peak AC), 1000 V CAT III
oscilloscope probe that provides 250 MHz performance and is
certified to international safety standards. The P5100 probe is
compatible with all general purpose oscilloscopes and with Tektronix
oscilloscopes that automatically detect 100X probe attenuation and
display the correct scale readout. The P5100 probe is designed for
ground-referenced measurements only.

WARNING. Do not substitute accessories from other products for
those provided with the P5100. The accessories for the P5100 have
been safety tested, and the use of non-tested accessories may cause
injury or death.

To reduce risk of electric shock, keep your fingers behind the finger
guard on the probe body. Place your fingers in front of the finger
guard only when retracting the hook-tip accessory.

Probe Body -- The P5100 probe body is designed for personal

safety, ergonomic comfort, and signal fidelity.

The probe body ground ring connection allows a short ground
connection for optimal signal fidelity.

The probe tip is a 6--32 threaded post that accepts both standard and
optional accessories.

Keep the probe body and accessories clean and dry to reduce the risk
of shock due to surface conduction. Refer to page 19 for cleaning
instructions.

Features and Accessories

P5100 Features and Standard Accessories (Cont.)

Compensation Box -- The P5100 compensation box contains low-

and high-frequency compensation adjustments as well as a
gain adjustment.

The P5100 is compatible with Tektronix oscilloscopes that automati­cally detect and display the 100X attenuation factor of the probe.

(If you have an older instrument with a lit vernier indicator, the 10X
position will light. Multiply the reading by a factor of 10 to get the true

Readout Pin

value.)

Ground Leads -- The P5100 probe comes with a long and a short

ground lead. Both ground leads connect to a removable crocodile clip.

Attach the ground lead to the probe body by inserting the probe head
into the ground lead as shown.

The length of the ground lead directly impacts the fidelity of high-fre­quency signals. The longer the ground lead, the more the signal will
be distorted. For more information about the ground lead and signal
quality, go to page 5.

Crocodile Clip -- The large crocodile clip attaches to the insulated

banana connector on the long ground lead.

Small Hook Tip -- Use the small hook tip for making connections to

small conductors such as component leads.

Install the small hook tip by sliding it over the body of the probe and
screwing it onto the threaded probe tip.

To use the tip, hold the probe body and pull the tip shield back. Hook
the tip onto the circuit and release the shield. The hook tip will firmly
hold the conductor under test.

P5100 Features and Standard Accessories (Cont.)

Large Hook Tip -- Use the large hook tip when working with larger

components such as bolt terminals and buss bars typically found in
power distribution equipment.

Install the large hook tip by sliding it over the body of the probe and
screwing it onto the threaded probe tip.

To use the tip, hold the probe body and pull the tip shield back. Hook the
tip ontothe circuit and releasethe shield. The hooktip will firmly hold the
conductor under test.

Features and Accessories

Color Marker

Bands

Color Marker Bands -- The color marker bands help you identify

multiple probes in the circuit under test.

Clip the matching bands onto the cable at the probe head and com­pensation box to help identify probe channels at a glance.

Adjustment Tool -- Use the adjustment tool for probe compensation

adjustments. Do not use metallic or conductive tools while making
adjustments.

Probe Tip to BNC Adapter -- Use the probe tip to BNC adapter to

connect the probe directly to BNC connectors. The adapter is
recommended for use when verifying or adjusting the probe.

WARNING. The BNC adapter is rated to 500 V (DC + peak AC). Do
not attempt to use the adapter for high voltage testing.

Attach the adapter by pressing it onto the 6-32 probe tip and making
sure that the ground clip makes contact with the ground ring.

Rubber Spring Tip -- Use the rubber spring tip to connect the P5100

to larger test sockets located in equipment or on printed circuit boards.

Connect the rubber spring tip by screwing it onto the threaded
probe tip.
