Operation
4 Operation
HANDLING THE PROBE
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.
CONNECTING THE PROBE TO THE TEST INSTRUMENT
The ZS1500 probe has been designed for use with LeCroy’s
WaveSurfer, WaveRunner, WaveMaster, and WavePro platforms
equipped with the ProBus interface. When you attach the probe output
connector to the oscilloscope’s input connector, the oscilloscope will
recognize the probe, provide proper termination and activate the probe
control functions in the user interface.
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 ZS1500 probe with its
small profile and low mass head ideally suited for applications in dense
circuitry.
OPERATION WITH A LECROY OSCILLOSCOPE
When the ZS1500 probe is connected to any compatible LeCroy
oscilloscope, the displayed scale factor and measurement values will be
automatically adjusted.
Control through the oscilloscope’s interface can be found in the
Coupling menu of the channel to which the probe is connected.
Turning the Volts/Div knob will control the oscilloscope’s scale factor to
give full available dynamic range up to 2 V/div.

High Frequency Measurements
5 High Frequency Measurements
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.
Figure 5-1. 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 L-C network. The impedance of a series LC network will
drop 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
F
Resonance
ZS1500-OM-E Rev C 5–1
------------------
=
2π LC
ZS1500 High Impedance Active Probe
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 (f
) of:
0
-------------------------------------------------------------------
f
0
2π 50 10
This frequency is well within the passband of the probe and will therefore show 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
t
rise
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.

High Frequency 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:

(parallel combination of 250 Ω and 1 MΩ is still 250 Ω)
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

CLEANING
The exterior of the probe and cable should be cleaned only using a soft
cloth lightly moistened with water or isopropyl alcohol. The use of abrasive agents, strong detergents, or other solvents may damage the
probe. Always ensure that the input leads are free of debris.
Note
The probe case is not sealed and should never be immersed in any
fluid.
CALIBRATION INTERVAL
The recommended calibration interval is one year. (Performance Verification and Adjustment Procedures are included in this manual.)
SERVICE STRATEGY
The ZS1500 probe utilizes fine pitch surface mount devices. It is therefore impractical to attempt to repair in the field. Defective probes must
be returned to a LeCroy service facility for diagnosis and exchange. A
defective probe under warranty will be replaced with a factory refurbished probe. 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 DEFECTIVE PROBE
The procedure for returning a defective probe is as follows:
Contact your local LeCroy sales representative to find out where to
return the product. All returned products should be identified by model
number and serial number. Provide your name and contact number and
if possible describe the defect or failure. In case of products returned to
the factory, a Return Authorization Number (RAN) should be used. The
RAN can be established by contacting your nearest LeCroy office, or the
New York Customer Care Center.
Return shipment should be made prepaid. LeCroy cannot accept COD
or Collect Return shipments. We recommend air-freighting. It is impor-
ZS1500-OM-E Rev C 6–1

tant that the RAN be clearly shown on the outside of the shipping package for prompt redirection to the appropriate department.
1. Contact your local LeCroy sales or service representative to obtain
a Return Authorization Number.
2. Remove all accessories from the probe. Do not include the manual.
3. Pack the probe in its case, surrounded by the original packing material (or equivalent) and box.
4. Label the case with a tag containing
• The RAN
• Name and address of the owner
• Probe model and serial number
• Description of failure
5. Package the probe case in a cardboard shipping box with adequate
padding to avoid damage in transit.
6. Mark the outside of the box with the shipping address given to you
by the LeCroy representative; be sure to add the following:
• ATTN: <RAN assigned by the LeCroy representative>
• FRAGILE
7. Insure the item for the replacement cost of the probe.
8. Ship the package to the appropriate address.
REPLACEMENT PARTS
The probe connection accessories and other common parts can be
ordered through the regional customer care centers. Refer to list below
for LeCroy part numbers. Defective probes can be replaced on an
exchange basis. The replacement exchange probe will have been factory repaired, inspected and calibrated to the same standards as a new

Performance Verification
7 Performance Verification
This procedure can be used to verify the warranted characteristics of
the ZS1500 High Frequency Probe.
The recommended calibration interval for the model ZS1500 is one
year. The complete performance verification procedure should be performed as the first step of annual calibration. Test results can be
recorded on a photocopy of the Test Record provided in Appendix A at
the end of the manual.
Performance verification can be completed without removing the probe
covers or exposing the user to hazardous voltages. Adjustment should
only be attempted if a parameter measured in the Performance Verification Procedure is outside the specification limits.
Note
Adjustment should only be performed by qualified personnel.
This procedure tests the following specifications:
• Output Zero Voltage
• Offset Accuracy
• LF Attenuation Accuracy
TEST EQUIPMENT REQUIRED
Table 7-1 lists the test equipment and accessories (or their equivalents)
that are required for performance verification of the ZS1500 Probe.
This procedure has been developed to minimize the number of calibrated test instruments required.
Only the parameters listed in boldface in the "Minimum requirements"
column must be calibrated to the accuracy indicated.
Because the input and output connectors types may vary on different
brands and models of test instruments, additional adapters or cables
may be required.

Adjustment Procedure
8 Adjustment Procedure
INTRODUCTION
You can use this procedure to adjust the ZS1500 probe to meet the warranted specifications. This procedure should only be performed if the
probe fails to meet the Performance verification tests for Output Zero or
Offset Accuracy.
Gain which affects LF attenuation accuracy cannot be adjusted during
routine calibration. Probes which fail LF frequency accuracy during performance verification must be returned to the factory for rework.
If the probe cannot be adjusted to meet the Performance verification limits, repair may be necessary.
To assure probe accuracy, check the calibration of the ZS1500 every
1000 hours or once a year if used infrequently. Before calibration, thoroughly clean and inspect the probe as outlined in the Care and Maintenance section.
To assure the probe will meet the published specifications over the
entire temperature range, adjustment must be performed in a controlled
ambient environment with temperature of 23 °C ±5 °C.
Caution
The adjustment procedure will require removal of the probe control circuit cover. This cover is part of the ESD protection system of the
ZS1500. To protect the probe, you should perform the entire procedure
on a static dissipating work surface. Wear an antistatic wrist strap and
follow standard static control procedures.
TEST EQUIPMENT REQUIRED
