    ZS4000 High-Impedance Active Probe 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 5: Introduction

    With low input capacitance and high input resistance, circuit loading is minimized. The ZS4000 can be used with a variety of Teledyne LeCroy oscilloscopes with MAUI firmware version 7.1.1.2 or later (see the product page at teledynelecroy.com/oscilloscope for compatibility).

    User 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.

    ZS4000 High-Impedance Active Probe Operation with a Teledyne LeCroy Oscilloscope When the ZS4000 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.
  • Page 15 User Manual 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.
  • Page 16 ZS4000 High-Impedance Active Probe 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 18: Performance Verification

    NOTE: The correct operation of the ZS4000 controls requires software version 7.1.1.2 or higher. The oscilloscope software version can be verified by going to Utilities > Utilities Setup > Status. Contact your local Teledyne LeCroy representative or visit teledynelecroy.com if the software in your oscilloscope requires updating.

  • Page 26: Care And Maintenance

    The ZS4000 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.
