Safety Information
This symbol appears on the product:
It refers you to additional information contained in this manual. The corresponding information in the manual is
similarly denoted.
To avoid personal injury and to prevent fire or damage to the probe or any products connected to it, review and
comply with the following safety precautions.
Connect to properly grounded instruments. This probe is to be used only with test instruments having input
connectors with the BNC shield (ring) connected to earth ground.
Connect the probe properly:
Connect the probe to the measurement instrument before connecting the probe to test circuit. Do not
disconnect the probe from the test instrument while the input is connected to the test circuit.
Do not connect the probe ground terminal to any point in the test circuit which is at a potential other than earth
ground.
Do not apply any potential to the input which exceeds the maximum ratings of the probe.
Comply with the voltage derating curve. When measuring high frequency signals, be sure to comply with the
Voltage vs. Frequency derating curve found on page 5.
Do not use in wet or explosive atmospheres.
For indoor use only. This probe is intended for indoor use and should be operated in a clean, dry environment.
Do not use the probe if any part is damaged. All maintenance should be referred to qualified service personnel.
Avoid physical injury. The probe tip is extremely sharp. Use care when handling to prevent injury, including
accidental skin puncture.
Use of the probe and/or the test instrument it is connected to in a manner not specified by the manufacturer may
impair the protection mechanisms.

Introduction
The PP011 is a miniature high impedance passive probe. Its high input resistance and low capacitance make it
ideal for general purpose probing of signals with frequency content from DC through several hundred MHz. The
PP011 has a large selection of connection accessories, supplied standard with the probe and available from
LeCroy as optional accessories.
The PP011 is designed for use with > 600 MHz LeCroy WaveSurfer oscilloscopes.

Use and Maintenance
This probe is a high quality, precision instrument. To maintain accuracy and signal fidelity, mechanical shock
should be avoided, as well as damage to the cable through excessive bending.
Avoid placing excessive force sideways on the tip.
Should the tip become damaged, it may be replaced by the user using the procedure listed on the last page.
Other maintenance and component replacement should be referred to qualified personnel.
Cleaning
The outside of the probe should be cleaned with a soft cloth dampened with either deionized / distilled water or
isopropyl alcohol. Allow the surface to dry completely before returning the probe to service. Never immerse the
probe in any liquid.

Probe Compensation
Proper compensation of the probe is required to assure good amplitude accuracy in the dynamic portions of the
waveform being measured. LF compensation matches the probe to differences in oscilloscope input capacitance.
The LF compensation should always be checked and adjusted as needed when first connecting a passive probe to
the oscilloscope input. HF compensation matches time constants within the probe to compensate for normal
component tolerances. It is typically not necessary to adjust HF compensation unless the probe is being used with
an oscilloscope with large differences in input characteristics than the oscilloscope model it was designed for.
LF compensation is performed by connecting the input of the probe to a low frequency square wave, such as the
oscilloscope calibrator signal set to 1 kHz. The compensation is adjusted by rotating the adjustment accessible
through the small hole in the center of the housing near the BNC connector. Use the tool supplied with the probe
for this adjustment.
Undershoot Overshoot Correct adjustment
Should HF compensation be required, access the
adjustments by sliding the black plastic cover off
the compensation housing near the BNC con-
nector. A pulse generator with low overshoot and
a 300 ps risetime is the required signal source,
along with a set of attenuators. The probe must be
connected to a terminated probe tip to BNC
adapter.
Some overshoot and ring will be present at some
settings of V/Div. Adjust the trimmer for the overall
best response on all ranges.

Tip Selection and Exchange
The PP011 probe is supplied with a rigid tip. The spring tips PK1-5MM-109 (0.8 mm) or PK1-5MM-124 (0.38 mm)
combine sharp points with on-axis compliance and can be ordered directly from LeCroy as optional accessories. All
three tip styles provide reliable connections under a wide range of physical interconnect situations. While lacking
the on-axis compliance feature of the spring tips, the rigid tip has a larger diameter and is more robust when
exposed to physical stress at the tip. Select the proper tip for your application needs.
To change the tip or replace it when damaged, carefully grip the outer most portion of tip and pull straight out,
along the axis of the probe, using needle nose pliers. Do not attempt to grip the plastic insulator with pliers when
removing the tip, as this will squeeze the tip, which will make it difficult or impossible to remove. Do not grip the
outer gold plated tube which the tip slides into. With the tip removed, align the replacement tip with the hole and
begin the insertion with the pliers. The tip may be fully seated by placing the probe against a hard surface and
gently applying pressure.
To remove tip, grip the spring-loaded portion of the tip Do not apply pliers to the plastic insulator.
