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.

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.

Grounds
Offset Ground
The Offset Ground is designed to be attached to
either socket of the probe head. The
Offset
Ground
connects 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
high
est 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.
ZS Series High-Impedance, Active Probes
6
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.

Probe Holder
Freehand Probe Holder
The FreeHand lets you focus on the oscilloscope
screen instead of on maintaining contact to
multiple test points. It allows
you to concentrate
on what is re
ally important – the waveform.
It is designed to keep most of the weight on the
probe tip and will prevent lost contact when a
bump to the table shakes the circuit under test.

Probe Operation
Handling the Probe
The ZS Series probes are precision test instruments. Exercise care when
handling and storing the probe. Always handle the probe by the probe body or
compensation box. Avoid putting excessive strain or exposing the probe
cable to sharp bends.
ESD Sensitive: The tips of the probes are sensitive to Electrostatic
Discharge (ESD). Avoid causing damage to the probe by always
following anti-static procedures (wear wrist strap, etc.) when using
or handling the probe.
Connecting the Probe to the Test Circuit
To maintain the high performance capability of the probe in measurement
applications, care must be exercised in connecting the probe to the test
circuit. Increasing the parasitic capacitance or inductance in the input paths
may introduce a “ring” or slow the rise time of fast signals. Input leads which
form a large loop area will pick up any radiated electromagnetic field which
passes through the loop and may induce noise into the probe input.
Using one of the available accessories makes the ZS probe with its small
profile and low mass head ideally suited for applications in dense circuitry.
Connecting the Probe to an Oscilloscope
ZS Series probes are designed for use with Teledyne LeCroy platforms
equipped with the ProBus interface. When you attach the probe output
connector to the oscilloscope’s input connector, the oscilloscope recognizes
the probe, provides proper termination, and activates the probe control
functions in the user interface.
Operator’s Manual
11
Operation with a Teledyne LeCroy Oscilloscope
When the ZS probe is connected to any compatible Teledyne LeCroy
oscilloscope, the displayed scale factor and measurement values are
automatically adjusted. A Probe dialog appears behind the corresponding
Channel dialog.
The probe can be controlled through the oscilloscope front panel:
• The Volts/Div knob controls the oscilloscope’s scale factor to give
full available dynamic range up to 2 V/div (16 V peak to peak).
• The channel Offset knob controls the probe input offset circuit over
its range of ±12 V.
Auto Zero
Auto Zero corrects for DC offset drifts that naturally occur from thermal
effects in the amplifier. The probe incorporates Auto Zero capability to
remove the DC offset from the probe's amplifier output to improve the
measurement accuracy.
Auto Zero is invoked manually from the ZSxxxx probe dialog that appears
when the probe is connected to the oscilloscope.
Always perform Auto Zero after the probe is warmed up (recommended
warm-up time is 20 minutes). Depending on the measurement accuracy
desired and/or changes in ambient temperature where the probe is located, it
may be necessary to perform Auto Zero more often. If the probe is
disconnected from the oscilloscope and reconnected, repeat Auto Zero after
a suitable warm-up time.
CAUTION: Disconnect the probe from the circuit before Auto Zero, or
else any DC component that is part of the Signal to be measured will
be zeroed out.

High Frequency Measurements
Probe Input Loading
When you touch a probe to the circuit under test, the probe will affect your
measurement because of the probe’s input impedance introduced into the
circuit. All probes present resistive, capacitive and inductive loading.
Inductive Loading (Lead Length)
A significant element in this circuit is the inductance shown in the input
ground leads of the oscilloscope probe.
Probe input equivalent circuit
The ground lead is the primary return path for the current resulting from the
input voltage acting on the probe’s input impedance. The ground lead and
input lead inductances act with the probe’s input capacitance to form series
LC network. The impedance of a series LC network drops dramatically at its
resonant frequency. This is the cause of the "ring" we often see after the
leading edge of pulses in measured waveforms.
This effect is referred to as ground lead corruption. Because it is impossible
to eliminate either the L or C from this circuit, the method to improve
waveform fidelity is to raise the resonant frequency beyond the bandwidth of
interest in the measurement.
The resonant frequency of a simple LC circuit can be represented by:
=
1
2√
The resonant frequency of a series LC circuit can be raised by decreasing the
inductance, capacitance or both. Since the input capacitance is already very
Operator’s Manual
13
low and cannot be reduced, you can only try to reduce the inductance. This
can be accomplished by using the shortest possible input lead as well as the
shortest possible ground lead.
For example, to obtain the shortest possible ground lead when measuring IC
related signals, attach a small piece of copper clad material to the top of the
IC package and connect this to the package grounding wires.
Using the shortest ground lead and input lead available makes probing
signals on the package easier and makes for the shortest lead length for the
best signal fidelity. To illustrate how dramatic this effect is, we will work a
simple example. Assuming an input capacitance of 0.9 pF and a total lead
length (input and ground) of 2 inches (inductance of ≈ 25 nH/inch) such a
setup may cause ringing with a resonant frequency (f0) of:
=
1
2√50 ∗ 10
−9
∗ 0.9 ∗ 10
−12
= 750
This frequency is well within the passband of the probe and therefore shows
up as part of the measured signal at faster time/div settings.
To determine how fast a waveform to be measured can be without causing
ringing on a probe like this, divide the BW (ringing frequency) of the probe
into 0.35:
=
0.35
=
0.35
750
= 0.47
Any input signal with a rise time faster than 0.47 ns can cause ringing.
ZS Series High-Impedance, Active Probes
14
Capacitive Loading
Capacitive loading is usually the most troublesome of the three loading
effects. It can affect the rise time, bandwidth and delay time measurements.
At higher frequencies the capacitive loading can affect the amplitude as well
as the waveshape of the measured signal by introducing an exponential
response to the waveform.
For a simple RC network the time constant of this exponential response is:
= 2.2 ×
×
Where
C
total
is the combined probe and circuit capacitance and
R
total
is
combined circuit and probe resistance.
For a setup where Ct = 0.9 pF and a source resistance is 250 Ω, the
measured rise time will be 0.495 ns, which will correspond to a bandwidth of
909 MHz, assuming no inductive loads.
= 2.2 × 0.9 × 10
−12
× 250 Ω = 0.495 ns
Parallel combination of 250 Ω and 1 MΩ is still 250 Ω
Example probe input equivalent circuit
To illustrate the effect of capacitive loading at higher frequencies:
• At frequency 750 MHz the reactance of the 0.9 pF capacitance is 236 Ω
• At frequency 1.0 GHz the reactance has been lowered to 177 Ω
If, at a given frequency, the source impedance is large with respect to the
input impedance, a measurable reduction in the output signal amplitude may
occur.

Care and Maintenance
Cleaning
The exterior of the probe and cable should be cleaned using a soft cloth
moistened with water. Abrasive agents, strong detergents, or other solvents
may damage the probe. Always ensure that input leads are free of debris.
CAUTION. The probe case is not sealed and should never be immersed
in any fluid.
Calibration Interval
The recommended calibration interval is one year from the time the probe is
put into service. The complete performance verification procedure should be
performed as the first step of annual calibration.
Service Strategy
The ZS probes utilize fine pitch surface mount devices. It is therefore
impractical to attempt to repair in the field. Defective probes must be
returned to a Teledyne LeCroy service facility for diagnosis and exchange.
Defective probes under warranty are repaired or replaced. A probe that is not
under warranty can be exchanged for a factory refurbished probe for a
modest fee. You must return the defective probe in order to receive credit for
the probe core.
Replacement Parts
The probe connection accessories and other common parts can be ordered
through the North America Customer Care Centers. Refer to the Standard
Accessories table (p.3).

Performance Verification
This procedure can be used to verify the warranted characteristics of a ZS
Series High Impedance Active Probe. It tests:
• Output Zero Voltage
• LF Attenuation Accuracy
Performance verification can be completed without removing the probe
covers or exposing the user to hazardous voltages.
NOTE: The correct operation of the ZS probe controls requires software
version 6.5.0.5 or higher. The oscilloscope software version can be verified
by going to Utilities > Utilities Setup > Status. Contact your local Teledyne
LeCroy representative or visit teledynelecroy.com if the software in your
oscilloscope requires updating.
Required Test Equipment
This procedure has been developed to minimize the number of calibrated test
instruments required. Only equipment listed in boldface must be calibrated to
the accuracy indicated. Because the input and output connector types may
vary on different brands and models of test instruments, additional adaptors
or cables may be required.
The warranted characteristics of the probe are valid at any temperature
within the Operating Environment (p.2) listed in this manual. However, some
of the other test equipment used to verify the performance may have
environmental limitations required to meet the accuracy needed for the
procedure. Be sure that the ambient conditions meet the requirements of all
the test equipment used in his procedure.
NOTE: The function generator used in this Performance Verification
Procedure is used for making relative measurements. Because the output of
the generator is measured with an oscilloscope in this procedure, it is not
required to calibrate the generator.
