Safety Instructions
Observe generally accepted safety procedures in addition to the precautions
listed here. The overall safety of any system incorporating this accessory is
the responsibility of the assembler of the system.
Symbols
These symbols appear on the probe body or in documentation to alert you to
important safety considerations.
CAUTION of potential for damage to equipment, or WARNING of
potential for bodily injury. Attend to the information, and do not
proceed until conditions are fully understood and met.
ELECTROSTATIC DISCHARGE (ESD) HAZARD. The probe is
susceptible to damage if anti-static measures are not taken.
Precautions
Connect and disconnect properly. Connect probe to the measurement
instrument before connecting the test leads to a circuit/signal being tested.
Use only within operational environment listed. Do not use in wet or explosive
atmospheres.
Use indoors only.
Keep product surfaces clean and dry.
Be careful with sharp tips. The tips may cause bodily injury if not handled
properly.
Use only accessories designed for use with the product.
Observe all terminal ratings. To avoid electric shock or probe damage, do not
use the probe above the input limits shown on the probe.

Introduction
The ZS4000 is a small, high-impedance active probe designed to meet today’s
increasing demand for measurements on a variety of test points. With low
input capacitance and high input resistance, circuit loading is minimized.
The ZS4000 can be used with a variety of Teledyne LeCroy oscilloscopes with
MAUI firmware version 7.1.1.2 or later (see the product page at
teledynelecroy.com/oscilloscope for compatibility). With the ProBus interface,
the probe becomes an integral part of the oscilloscope, controlled from the
oscilloscope’s front panel. The oscilloscope provides power to the probe, so
there is no need for a separate power supply or batteries.
See the ZD4000 product page at teledynelecroy.com for probe specifications.

Tips
Straight Tip
The straight tip is rugged and designed for general
probing. Fits in either probe socket.
IC Lead Tip
The IC Lead Tip is covered in insulation on all sides
(except for a small edge), this tip was designed to
prevent shorting neighboring IC leads. The gold
part of the tip is not insulated and should touch the
IC lead to be tested. It is one
-size-fits-all and will
work with any IC lead pitch. Fits in either probe
socket.
Bent Tip
The Bent Tip is made out of titanium, this tip is
ideal for situations that require
you to hold the
probe parallel to the c
ircuit board under test. Also
gives you more control when holding the probe like
a pencil. Fits in either probe socket.
Pogo Tip
The pogo tip provides z-axis compliance. The tip
can fit into a socket or onto a
n IC leg.
Right-Angle Socket
The Right Angle Socket allows the probe to be
connected to a pin on the board under test, while
keeping the probe parallel to the board.

Grounds
2.54 mm Square Pin Adaptor
The 2.54 mm square pin adaptor fits into the
ground socket of the ZS4000 probe for easy
connection to standard 2.54 mm square pin
spacing on a circuit board.
Offset Ground
The Offset Ground is designed to be attached to
either socket of the probe head. The
Offset Ground
connect
s to the ground socket and wraps around
the probe head
, making it possible to probe a
signal and ground that are extremely close
together. The short length provides
the highest
quality grounding for high
frequency applications.
Narrow Ground Blade and
Copper Pad
The Narrow Ground Blade and Copper Pad
together are
the best grounding solution for
probing an IC. The
Narrow Ground Blade is
designed to provide a short, low inductance ground
path. The Copper Pad is adhesive backed to stick
to the top of an
IC, and can then be soldered to the
IC ground.
Wide Ground Blade
The Wide Ground Blade is ideal for use when the
best quality ground is needed. The wide blade
offers the minimal inductance compared to the
narrow ground blade.

Pogo Ground Lead
The Pogo Ground Lead allows flexibility for
bend
ing and positioning the ground lead onto hard
-
to
-reach test points, while maintaining z-axis
compliance.
2.54 mm PCB Adaptor
The 2.54 mm PCB adaptor fits into the tip
socket of the ZS4000 probe for easy connection
to standard 2.54 mm square pin spacing on a
circuit board.
Leads
While longer leads provide greater flexibility when connecting the probe to a
circuit, the added inductance may degrade the fidelity of high frequency
signals.
Short and Long
Straight Pin Lead
These leads have a socket on one end and a
square pin on the other to connect to the input or
ground socket of the probe body
and may be used
for general purpose probing.
Short and Long
Right Angle Pin Lead
These leads have a socket on one end with a right
angle and a square pin on the other to connect to
the input or ground socket of the probe body
and
may be used for general purpose probing.

Y Lead
This lead is used for both ground and input lead
simultaneously. It has two sockets on one end and
two square pins on the other and may be used for
general purpose probing.
Clips and Grabbers
Channel ID Clips
The Channel ID Clips can be attached to the probe
cable to quickly identify to which channel the probe
is currently connected: CH1 yellow, CH2 red, CH3
green, and CH4 blue.
Micro-Grabbers
The micro
-grabbers are ideal for connecting to
small IC legs or pins very tightly spaced.
QFPIC Clips
The QFPIC clips are ideal for connecting to the legs
or pins of Quad Flat Pack ICs.
