    Operator’s Manual Safety Instructions Observe generally accepted safety procedures in addition to the precautions listed here. The overall safety of any system incorporating this accessory is the responsibility of the assembler of the system. Symbols These symbols appear on the probe body or in documentation to alert you to important safety considerations.

  • Page 8: Introduction

    With low input capacitance and high input resistance, circuit loading is minimized. The ZS probes can be used with a variety of Teledyne LeCroy oscilloscopes with MAUI firmware version 6.5.0.5 or later (see the product page at teledynelecroy.com/oscilloscope for compatibility).

  • Page 10: Tips

    ZS Series High-Impedance, Active Probes Tips Straight Tip The straight tip is rugged and designed for general probing. Fits in either probe socket. 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.

  • Page 11: Grounds

    Operator’s Manual Grounds Offset Ground The Offset Ground is designed to be attached to either socket of the probe head. The Offset Ground connects to the ground socket and wraps around the probe head, making it possible to probe a signal and ground that are extremely close together.

    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. Short and Long These leads have a socket on one end and 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 you 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.

  • Page 16: Probe Operation

    Probe Operation Handling the Probe The ZS 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.

  • Page 17: Operation With A Teledyne Lecroy Oscilloscope

    Operator’s Manual Operation with a Teledyne LeCroy Oscilloscope When the ZS probe is connected to any compatible Teledyne LeCroy oscilloscope, the displayed scale factor and measurement values are automatically adjusted. A Probe dialog appears behind the corresponding Channel dialog. The probe can be controlled through the oscilloscope front panel: The Volts/Div knob controls the oscilloscope’s scale factor to give...

  • Page 18: High Frequency Measurements

    ZS Series High-Impedance, Active Probes 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.
  • Page 19 Operator’s Manual 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.
  • Page 20 ZS Series High-Impedance, Active Probes 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.

  • Page 22: Care And Maintenance

    The ZS 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.
