Operator’s Manual Safety Instructions This section contains instructions that must be observed to keep this oscilloscope accessory operating in a correct and safe condition. You are required to follow generally accepted safety procedures in addition to the precautions specified in this section. The overall safety of any system incorporating this accessory is the responsibility of the assembler of the system.
WavePro and WaveMaster series platforms with firmware version 6.5.0.5 or later. With the ProBus interface, the ZS1000, ZS1500, and ZS2500 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.
Operator’s Manual Standard Accessories The ZS1000, ZS1500, and ZS2500 probes are shipped with the following standard accessories: Standard Accessory Quantity Replacement Part Number Straight Pin Lead – Short PK-ZS-003 Straight Pin Lead – Long PK-ZS-004 Right Angle Lead – Short PACC-LD003 Right Angle Lead –...
ZS Series High-Impedance, Active Probes Features and Accessories The ZS1000, ZS1500, and ZS2500s probes are provided with numerous features and accessories to make probing and connecting to different test points easier than ever. • The small, low mass probe head is designed for ease of use and high performance.
Operator’s Manual 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.

ZS Series High-Impedance, Active Probes Tips, continued 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. 2.54 mm Square Pin 2.54 mm Square Pin Adapter.
Operator’s Manual 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.
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 These leads have a socket on one end and a square pin Straight Pin Lead on the other to connect to the input or ground socket of the probe body, and may be used for general...
(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...
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.
Operator’s Manual 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.
Page 18
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.

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.
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.

Operator’s Manual Return shipment should be prepaid. Teledyne LeCroy cannot accept COD or Collect Return shipments. We recommend air-freighting. Follow these steps for a smooth product return. 1. Contact your local Teledyne Lecroy sales or service representative to obtain a Return Material Authorization.
This procedure can be used to verify the warranted characteristics of the ZS1000, ZS1500, and ZS2500 High Impedance Active Probe. The recommended calibration interval for the model ZS1000, ZS1500, and ZS2500 is one year. The complete performance verification procedure should be performed as the first step of annual calibration.
Pomona 5187-C-36 Cable, 36” Preliminary Procedure 1. Connect the ZS1000, ZS1500, or ZS2500 probe to the female end of the ProBus Extension Cable. Connect the male end of the ProBus Extension Cable to channel 1 of the oscilloscope. 2. Turn the oscilloscope on and allow at least 30 minutes warm-up time for the ZS1000, ZS1500, or ZS2500 and test equipment before performing the Verification Procedure.
20 mV/div to 2 mV/div. 7. Reconnect the ProBus extender Cable to the oscilloscope. The warranted characteristics of the ZS1000, ZS1500, and ZS2500 are valid at any temperature within the Environmental Characteristics listed in the Specifications.
Operator’s Manual Verification Procedure A. Output Zero Voltage Output Zero Voltage Test Setup 1. Connect one end of a BNC cable to the female BNC connector on the probe end of the ProBus extender cable. Connect the precision 50 Ω terminator to the other end of the BNC cable.

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.
