Tips
Straight Tip
The straight tip is rugged and designed for general
probing. Fits in either probe socket. (PK-ZS-001)
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. (PACCPT003)
Bent Tip
The Bent Tip is made out of titanium, this tip is ideal
for situations that require the user 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. (PACC-PT005)
Pogo Tip
The pogo tip provides z axis compliance. The tip can
fit into a socket or via and onto an IC leg.

Grounds
Offset Ground
The offset pin is designed to be attached to either socket
of the probe head. The offset pin is the highest quality
grounding solution and is recommended in high
frequency applications.
The offset ground is designed to connect to the ground
socket and wrap around the probe head. This gives the
ability to a probe signal and ground that are extremely
close together. The short length provides high-quality
grounding for high-frequency applications.
Ground Blade
(narrow) and
Copper Pad
The Ground Blade and Copper Pad are intended to work
together for the best grounding solution for probing an
IC. The 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.
Ground Blade (wide) 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.
924282-00 Rev A

ZS Series High-Impedance, Active Probes
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.
See Section 4 for additional information.
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 Adapter
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.
Grabbers
Micro- and MiniGrabbers
8
The micro-grabbers are ideal for connecting to small
IC legs or pins very tightly spaced.
924282-00 Rev A
Operator’s Manual
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 the user to concentrate on what is
really 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 probe is a precision test instrument. 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 an Oscilloscope
The ZS1000, ZS1500, and ZS2500 probes have been designed for use with
Teledyne LeCroy’s WaveSurfer, WaveRunner, WavePro, and WaveMaster
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.
924282-00 Rev A

ZS Series High-Impedance, Active Probes
Operation with a Teledyne LeCroy Oscilloscope
When the ZS1000, ZS1500, or ZS2500 probe is connected to any compatible
Teledyne LeCroy oscilloscope, the displayed scale factor and measurement
values are automatically adjusted.
The probe can be controlled through the oscilloscope graphical user interface.
When connected, a Probe dialog appears behind the corresponding channel
dialog. Refer to your oscilloscope’s manual for specific operation instructions.
Turning 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). Turning the channel
Offset knob controls the probe input offset circuit over its range of ±12 V.
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 ZS2500 probe with its small
profile and low mass head ideally suited for applications in dense circuitry.

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.
Example probe input equivalent circuit. Actual diagrams p.14.
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 L-C
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:
924282-00 Rev A
11
ZS Series High-Impedance, Active Probes
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 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:
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:
Any input signal with a rise time faster than 0.47 ns can cause ringing.
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:
12
924282-00 Rev A
Operator’s Manual
Where Ctotal is the combined probe and circuit capacitance and Rtotal 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.
trise = 2.2 x 0.9 x 10-12 x 250 Ω = 0.495 ns
Parallel combination of 250 Ω and 1 MΩ is still 250 Ω
Example Probe input equivalent circuit. Actual diagrams p.14.
To illustrate the effect of capacitive loading at higher frequencies:
At a frequency of 750 MHz the reactance of the 0.9 pF capacitance is 236 Ω, and
at 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.
where Zprobe is the probe’s input impedance and Zsource is the source
impedance.
For example: At 750 MHz, where the probe input impedance has reduced to 236
Ω, and a source resistance of 250 Ω the probe output amplitude is reduced to:

Care and Maintenance
Cleaning
The exterior of the probe and cable should be cleaned, using a soft cloth
moistened with water. The use of abrasive agents, strong detergents, or other
solvents may damage the probe. Always ensure that the 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.
Service Strategy
The ZS1000, ZS1500, and ZS2500 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.
Returning a Probe for Calibration or Service
Return a probe for calibration or service by contacting your local Teledyne
LeCroy sales representative. They will tell you where to return the product. All
returned products should be identified by both model and serial number.
Provide your name and contact number, and a description of the defect or
failure (if possible).
Products returned to the factory require a Return Material Authorization (RMA)
acquired by contacting your nearest Teledyne LeCroy sales office, representative
or the North America Customer Care Center.
NOTE: It is important that the RMA be clearly shown on the outside of the
shipping package for prompt redirection to the appropriate department.

of the probe head. Attach the red lead of the mini-grabber to the signal
input and the black lead to the ground input of the probe head.
3. Connect the BNC tee to the output of the function generator. (Use a 50 Ω
termination if the function generator requires such a load).
4. Attach a BNC cable to the unused female port of the BNC tee and connect a
dual banana plug adapter to the other end of the cable and plug the dual
banana plug adapter into the DMM input. Be sure the side of the banana
plug adapter corresponding to the BNC shield (marked "GROUND") is
connected to the LOW or COMMON input of the DMM.
5. Set the DMM to read AC volt and set the range to measure 5.0 Vrms.

6. Set the mode of the function generator to sine wave, the frequency to 70 Hz
and the output amplitude to 5 Vrms ±10 mV as measured on the DMM.
7. Record the output voltage to 1 mV resolution as "Generator Output Voltage"
in the Test Record. Be careful not to alter the output amplitude after the
reading is recorded.
8. Divide the reading recorded in step B-7 by 10 and record the result with 100
μV resolution as "Expected Output Voltage, top range" in the Test Record.
9. Remove the banana plug adapter, connected to the function generator,
from the DMM and connect the precision 50 Ω terminator to the DMM,
making sure that the banana plug side marked "GROUND" is connected to
the LOW or COMMON input of the DMM.
10. After the DMM reading has stabilized, record the reading to 100 μV
resolution as "Measured Output Voltage, top range" in the Test Record.
11. Calculate the error by dividing the measured top range output voltage
recorded in step B10 by the expected top range output voltage recorded in
step B-8. Subtract 1 from this ratio and multiply by 100% to get the error in
percent.
12. Record the calculated error to two decimal places (±0.xx%) as "Gain Error,
top range" in the test record.
13. Verify that the error is less than ±1.0 %.
14. Disconnect the precision 50 Ω terminator from the DMM.
15. Connect the banana plug adapter connected via a BNC cable to the BNC tee
at the function generator to the DMM. Verify that the side of the plug
marked ’Ground’ is connected to the Low or Common input of the DMM.
16. Adjust the sine wave generator output amplitude to approximately 2.5 Vrms
as measured on the DMM.
17. Record the reading to 1 mV resolution as "Generator Output Voltage, mid
range" in the Test Record. Be careful not to alter the output amplitude after
the reading is recorded.
18. Divide the reading recorded in step B-17 by 10.
19. Record the result to 100 μV resolution as "Expected Output Voltage, mid
range" in the test record.

20. Remove the banana plug adapter from the DMM and connect the precision
50 Ω terminator to the DMM, making sure that the banana plug side marked
"GROUND" is connected to the LOW or COMMON input of the DMM.
21. After the DMM has stabilized, record the reading to 100 μV resolution as
"Measured Output Voltage, mid range" in the Test record.
22. Calculate the error by dividing the measured mid range output voltage
recorded in step B-21 by the expected mid range output voltage recorded in
step B-19. Subtract 1 from this ratio and multiply by 100% to get the error in
percent.
23. Record the calculated error to two decimal places (±0.xx %) as "Gain Error,
mid range" in the Test record.
24. Verify that the mid range gain error is less than ±1.0%
This completes the Performance Verification of the ZS1000, ZS1500, or ZS2500.
Complete and file the Test Record, as required to support your internal
calibration procedure.
Apply suitable calibration label to the ZS1000, ZS1500, or ZS2500 housing as
required.
NOTE: The function generator used in this Performance Verification Procedure is
used for making relative measurements. The output of the generator is
measured with a DMM or oscilloscope in this procedure. Thus, the generator is
not required to be calibrated.
Performance Verification Test Record
The next page can be used to record the results of measurements made during
the performance verification of the ZS Series Probes. Permission is granted to
photocopy it and record the results on the copy. File the completed record as
required by applicable internal quality procedures. The section in the test record
corresponds to the parameters tested in the performance verification
procedure. The numbers preceding the individual data records correspond to
the steps in the procedure requiring the recording of data.
Results to be recorded in the column labeled Test Result are the actual
specification limit check. The test limits are included in all of these steps. Other
measurements and the results of intermediate calculations that support the limit
check are to be recorded in the column labeled Intermediate Results.
