Introduction
The ZD Series of Differential Probes (ZD500, ZD1000 and ZD1500) are high bandwidth active
differential probes. The probes feature low noise, very high input impedance and high common
mode rejection, and are ideally suited for signal integrity measurements in high-speed digital
systems.
With low input capacitance and high input resistance, circuit loading is minimized.
The ZD Series probes can be used with LeCroy’s WaveSurfer, WaveRunner, WavePro, and
WaveMaster series platforms with firmware version 6.4.1.x or later.
With the ProBus interface, the ZD Series probes become an integral part of the oscilloscope. The
probe can be 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.

Probe Calibration Fixture
The probe deskew fixture (PCF-200) is provided as a standard accessory with ZD500, ZD1000,
and ZD1500 probes.
The fixture can be used one of two ways:
1.
The fixture may be used to determine the effect of probe input loading on the
circuit under test and verification of the probe response to the signal being measured.
2.
The fixture may be used as a convenient way to deskew several
probes/oscilloscope channels. This can be accomplished in the following ways:
 Connect a fast edge to one or both inputs, and terminate the corresponding
connector. Connect the probe tip(s) to the appropriate connection point.
Solder-in probe tips and browser tips may be inserted under the clamping
mechanism. Display the probe signals on the oscilloscope screen and use the
channel deskew adjust to align them to a common point.
 Connect the WavePro 7 Zi and Zi-A or WaveMaster 8 Zi and Zi-A fast edge
output to one of the inputs. Set the Zi Series oscilloscope to trigger on the
internal Fast Edge source. Set the trigger delay to zero. Now, on the vertical
dialog, use the Probe Cal - Cable Deskew button to align one signal/channel at a
time to the specified zero delay trigger point (center of screen). Repeat for as
many probes as you have connected, each time aligning them to the common
point.

Instruction Manual
Probe Operation
Handling the Probe
The ZD 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 ZD Series 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 a LeCroy Oscilloscope
The ZD Series 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 recognizes
the probe, provides proper termination and activates the probe control functions in the user
interface.
Operation with a LeCroy Oscilloscope
When the ZD Series probes are connected to any compatible LeCroy oscilloscope, the
displayed scale factor and measurement values are automatically adjusted.
Control through the oscilloscope’s interface can be found on the channel dialog that
corresponds with the connected probe. 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 2.25 V/div.
ZDSERIES-GSM-REVA

ZD Series Differential Probes
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 ZD Series probe with its small profile and low
mass head ideally suited for applications in dense circuitry.
ZDSERIES-GSM-REVA

Instruction Manual
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.
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 ZD Series 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. 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 LeCroy sales representative.
They 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

Instruction Manual
B. LF Attenuation Accuracy
1. Disconnect the BNC tee at the power supply from the dual banana plug adapter.
Connect the BNC tee to the output of the function generator. (Use a 50 Ω
termination if the function generator requires such a load.)
2. Carefully insert the Straight Tips (supplied in accessory kit) into the sockets of the
probe head. Attach the red lead of the mini-grabber to the positive (+) signal
input and the black lead to the negative (-) 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 the Effective Gain noted in step 6 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 1 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. Set the scope to 200mV/div and note the “Effective Gain” under the ZDxxx tab of
the channel setting menu.
19. Divide the reading recorded in step B-17 by Effective Gain noted in step 18.
20. Record the result to 100 μV resolution as "Expected Output Voltage, low range"
in the test record.
21. 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.
22. After the DMM has stabilized, record the reading to 100 μV resolution as
"Measured Output Voltage, mid range" in the Test record.
23. 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.
24. Record the calculated error to two decimal places (±0.xx %) as "Gain Error, low
range" in the Test record.
25. Verify that the mid range gain error is less than ±1.0%
This completes the Performance Verification of the ZD Series. Complete and file the Test Record,

ZD Series Differential Probes
Probe Input Loading
Attaching any probe to a test circuit add some loading to the circuit under test. In most
applications the high impedance of the probe, compared to the impedance of the circuit under
test, imparts an insignificant load to the test circuit. However, at very high frequencies the
capacitive reactance of the probe tip or lead may load the circuit enough to affect the
measurement. These probes are designed to minimize these effects at high frequencies. Refer
to the figures in this topic for equivalent input circuit information.
