P3010 Passive Probe Instructions 1
General Safety Summary
Review the following safety precautions to avoid injury and prevent
damage to this product or any products connected to it. To avoid
potential hazards, use this product only as specified.
To Avoid Fire or Personal Injury
Observe Maximum Working Voltage. Do not use the P3010 probe above
300 VRMS, CAT II. Refer to the derating chart, Figure 2, on page 12.
Connect and Disconnect Properly. Connect the probe output to the
measurement instrument before connecting the probe to the circuit
under test. Disconnect the probe input and the probe ground from the
circuit under test before disconnecting the probe from the measure-
ment instrument.
Do Not Elevate the Common Terminal. The common terminal is at
ground potential. Do not connect the common terminal to elevated
voltages.
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.

Features and Accessories
The P3010 probe is compatible with TDS3000 series 100 MHz
oscilloscopes. The probe is also compatible with Tektronix
oscilloscopes that automatically detect probe attenuation and adjust
the scale readout accordingly.
NOTE. Remove and discard the protective cover on the tip of the
probe before attempting to connect a probe tip accessory.
BNC-to-probetip adapter. To install the adapter,
push the wide end firmly into a BNC connector.
Then insert the probe tip firmly into the adapter.
Retractable hook tip. Use the retractable hook tip to
make hands-free measurements.
NOTE. For a solid connection, firmly push and
twist the hook tip onto the probe tip before using.
Readout Pin
Readout pin. The P3010 is compatible with Tektro-
nix oscilloscopes that automatically detect and
display the attenuation factor of the probe.

Features and Accessories

Marker rings. Attach the matching colored rings
onto the probe cable and tip as shown.
Adjustment tool. Use the adjustment tool for probe
compensation adjustments.

Guard
Guard. The guard provides a finger barrier for
protection from electric shock.
WARNING. To avoid electric shock when using the probe, keep
fingers behind the guard on the probe body.
Ground Lead. Use the alligator clip to attach the
probe to a ground reference.
Long Ground Lead
Short Ground Lead
To see the best signal, use the shortest possible ground lead and
signal path.

Maintenance
This section describes how to maintain the probe.
Low-Frequency Probe Compensation
Before taking any measurements using a probe, first check the
compensation of the probe and adjust it to match the channel inputs.
Most oscilloscopes have a square wave reference signal available at
a terminal on the front panel used to compensate the probe.
1. Connect the probe to the signal source to display a 1 kHz test
signal on your oscilloscope.
2. Adjust the LF trimmer on the probe so that the corners of the
square wave are square and the top is flat.

High-Frequency Probe Compensation
The probe high-frequency compensation should seldom require
adjustment; however, your probe may require high-frequency
adjustment if any of the following are true:
Hthe probe has high-frequency aberrations
Hthe probe does not perform at the rated bandwidth
Hyou have installed the probe on an oscilloscope having an input
capacitance near the limits of the probe compensation range (See
Table 1.)
To perform the high-frequency compensation adjustment you will
need a signal source that has all of the following characteristics:
1 MHz
tr<1 ns
90%
10%
>1 Vp-p
Hsquare-wave output at 1 MHz
Hfast rise output with rise time less than 1 ns
Houtput properly terminated

1. Connect the probe to the signal source to display a 1 MHz test
signal on your oscilloscope. The display should be similar to that
shown in Figure 1(a).
2. Adjust the HF trimmer until the waveform is flat on top and has a
square leading edge.

Cleaning
To prevent damage to probe materials, avoid using chemicals that
contain benzine, benzene, toluene, xylene, acetone, or similar
solvents.
Do not immerse the probe or use abrasive cleaners.
Dirt may be removed with a soft cloth dampened with a mild
detergent and water solution, or isopropyl alcohol.

Maintenance

Replacing Probe Parts
Other than accessories, only the probe tip is replaceable.
Replacement probe tips are available as optional accessories. Refer
to the replaceable parts list at the end of this manual for more
information.
To remove a tip assembly, firmly grasp the pointed tip with pliers
and withdraw the assembly from the barrel.
No tools are required to install a replacement tip. Insert a new probe
tip into the probe barrel as far as possible using finger pressure. If
necessary, seat the plastic portion of the tip against the probe barrel
by pressing the tip gently but firmly against a hard surface, such as a
wood block or table top.
