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.
Do not excessively bend cables.
Do not operate with suspected failures. Do not use the probe if any part is
damaged. Cease operation immediately and secure the probe from
inadvertent use.

Operating Environment
The accessory is intended for indoor use and should be operated in a clean,
dry environment. Before using this product, ensure that its operating
environment is maintained within these parameters:
Temperature: 0 to 40° C
Humidity: Maximum relative humidity 80 % for temperatures up to 31 °C
decreasing linearly to 50 % relative humidity at 40° C
Altitude: Up to 10,000 ft (3,048 m)
Introduction
The ZS Series (ZS1000, ZS1500, and ZS2500) are a small, high-impedance
active probes 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 ZS probes can be used with a variety of Teledyne LeCroy oscilloscopes
with MAUI firmware version 6.5.0.5 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 ZS product page at teledynelecroy.com for probe specifications.
Key Benefits
Features
High frequency performance
Low input capacitance
Wide dynamic range
ProBus interface
Small, low mass probe head is designed
for ease of use and high performance.
Probe tip socket fits easily onto 0.025
inch square pins for direct access to
test points. Several available adaptors
connect directly to the probe socket.
Ground socket accepts several different
ground leads to provide a short ground
path for high frequency performance.

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
si
des (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 circuit 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.
Discrete SMD Tip
The crescent shape of this tip is designed to fit
tightly on capacitors, resistors, transistors and
other surface mount components with discrete
leads. Fits in either probe socket
.
2.54mm Square Pin Adapter
2.54 mm Square Pin Adapter. The 2.54 mm
square pin adapter fits into both the
input and
ground lead of the ZS probe for easy connection
to standard 2.54 mm square pin spacing on a
circuit board.
