  • Page 21: Safety

    Operator’s Manual Safety To maintain the probe in a correct and safe condition, observe generally accepted safety procedures in addition to the precautions specified in this section. The overall safety of any system incorporating this product is the responsibility of the assembler of the system. These symbols appear on the probe and accessories or in this manual to alert you to important safety considerations.

  • Page 22: Safe Operating Environment

    60 V Common Mode Differential Probes Do not remove the probe's casing. Touching exposed connections may result in electric shock or burn. CAUTION. To prevent damage to the equipment: Use only as specified. The probe is intended to be used only with compatible Teledyne LeCroy instruments.

  • Page 23: Operation

    On the top (label) side is an LED indicator that lights in the color of the channel to which the probe is connected. On the bottom is the ground lead input. 60 V common mode probes have been designed for use with Teledyne LeCroy oscilloscopes equipped with the ProBus interface. To connect to the instrument, press the amplifier connection box onto the oscilloscope’s ProBus connector until you hear a click.

  • Page 24: Freehand Probe Holder

    60 V Common Mode Differential Probes Freehand Probe Holder The optional Freehand Probe Holder is designed to position the amplifier while maintaining a steady weight on the probe tip to prevent loss of contact with the circuit under test. Turn the mounting head until the amplifier legs are in the desired position.

  • Page 25: Connecting Tips

    Operator’s Manual Connecting Tips Two inputs are available on all probe tips. The red lead connects to the + signal, and the black lead to the – signal. For accurate measurements, both the + and –must be connected to the circuit under test. To maintain the probe's high performance, exercise care when connecting tips to a circuit.
  • Page 26 60 V Common Mode Differential Probes Hi-Temp Lead The Hi-Temp lead attaches to the board exactly as do the solder-in tips. The long lead provides isolation from the DUT when it is in an environmental chamber. Y-lead Sockets The 2” and 5” Y-lead sockets provide flexibility for probing points far apart on the board, or deep within spaces where the amplifier cannot fit.
  • Page 27 Operator’s Manual Mini-Grabbers The mini-grabbers can be used to connect to very tightly spaced pins and legs. 1. Attach a Y-lead to the side of the T-bar. 2. Pull back on the wings to expose the hook. 3. Seat the hook over the probing point. 4.
  • Page 28 60 V Common Mode Differential Probes Browser Tip The browser tip has a very small form factor with very low mass and variable tip spacing. It is a good, all-around solution for probing in areas with a high concentration of test points or limited free space to fit a probe.
  • Page 29 Operator’s Manual Ground Lead The bendable, socket-tipped ground lead can be used alone, or with the single pin or grabbers inserted for probing ground planes. Insert the right-angled pin of the ground lead into the receptacle on the underside of the amplifier body, immediately below the differential input.

  • Page 30: Using The Pcf-200 Deskew Fixture

    60 V Common Mode Differential Probes Using the PCF-200 Deskew Fixture The PCF-200 deskew fixture may be used to determine the effect of probe input loading on the circuit under test, for verification of the probe’s response to the signal being measured, or as a convenient way to deskew the signal path.

  • Page 31: Operating From The Oscilloscope

    Operator’s Manual Operating from the Oscilloscope When the probe is connected to a Teledyne LeCroy oscilloscope, the displayed scale factor and measurement values will be adjusted to account for the effective gain of the probe. The probe’s internal attenuation is shown on the DLxx-CHM probe dialog, which is added to the oscilloscope's input channel dialogs when a probe is detected.
  • Page 32 60 V Common Mode Differential Probes Auto Zero Auto Zero corrects for DC offset drifts that naturally occur from thermal effects in the differential amplifier. For example, the DC offset drift of the 60 V common mode probes is 250 μV/°C (worst case) referred to the output. If the probe is set to 7.5x attenuation and the ambient temperature changes by 10 °C, the DC offset drift could be as high as (250 μV/°C)(7.5)(10 °C) = 18.75 mV referred to the probe tip.

The probe dialog will indicate when the probe has a valid calibration and Precision Gain Calibration is in use: The probe dialog will also show that a calibration is needed when any of the calibrated conditions change by placing a red “X”...

  • Page 34: Maintenance

    Service Strategy DL-HCM probes utilize fine-pitch surface mount devices. It is, therefore, impractical to attempt repair in the field. Defective probes must be returned to a Teledyne LeCroy service facility for diagnosis and exchange. CAUTION. Do not remove the covers. Refer all servicing to qualified personnel. A defective probe under warranty will be replaced with a factory refurbished probe.

  • Page 35: Returning A Product For Service

    Operator’s Manual Returning a Product for Service Contact your regional Teledyne LeCroy service center for calibration or other service. If the product cannot be serviced on location, the service center will give you a Return Material Authorization (RMA) code and instruct you where to ship the product. All products returned to the factory must have an RMA.
