Instruction Manual 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.

Instruction Manual Features and Accessories The ZD Series 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. The probe tip socket fits easily onto 0.025 inch square pins for direct access to test points. Several different adapters are available which connect directly in the probe socket.
ZD Series Differential Probes Tip Saver To prevent excessive wear on the probe input leads, it is recommended to use tip saver in most probing scenarios. The tip saver offers full system bandwidth and will not degrade signal under test. Grabbers Micro- and Mini-Grabbers The micro- and mini-grabbers are ideal for connecting to small IC legs or pins very tightly spaced.
Instruction Manual Grounds Long and Short Spring Loaded Bendable Ground The bendable ground leads are designed to be attached to the offset ground socket or be attached to either socket of the probe head. The following image is an example using the short spring-loaded, bendable ground.
ZD Series Differential 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. Short and Long Right Angle Lead This lead has 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 or can be connected to the Mini-Grabber or Micro-Grabber accessories.
Instruction Manual 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. Resistive compensation to reduce inductive peaking is included. Solder-In Lead This lead can be soldered directly to the test points for a secure probe connection. Small IC Adapter The Small IC adapters are designed for probing the leads of an IC.
ZD Series Differential Probes 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.
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.
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.
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.
ZD Series Differential Probes Products returned to the factory require a Return Material Authorization (RMA) acquired by contacting your nearest LeCroy sales office, representative or the North America Customer Care Center. Return shipment should be prepaid. LeCroy cannot accept COD or Collect Return shipments. We recommend air-freighting. Note: It is important that the RMA be clearly shown on the outside of the shipping package for prompt redirection to the appropriate department.
Instruction Manual Returning a Probe to a Different Country Note: Be sure to properly mark shipments returned for service from a different country to avoid customs duty for a full purchase price of a new probe or accessory. In addition to the items mentioned in the previous topic, mark shipments returned for service as a Return of US manufactured goods for warranty repair/recalibration.
ZD Series Differential Probes Replacement Parts The probe connection accessories and other common parts can be ordered through the North America Customer Care Centers.

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.
