- Page 13 User Manual Typical Step Response (cont’d) Note: Unless full bandwidth is required, we recommend applying a bandwidth filter when using the Browser to reduce peaking. The plot above shows the results.
- Page 14 60 V Common Mode Differential Probes Typical CMRR Performance Differential probes sense the voltage difference that appears between the + and – inputs, referred to as the normal or differential mode voltage. The voltage component that is referenced to earth and is identical on both inputs is rejected by the amplifier. This is referred to as the common mode voltage and can be expressed: V = (V +input...
- Page 15 User Manual numbers indicate greater rejection (better performance). The first order term determining the CMRR is the relative gain matching between the + and – input paths. You can obtain high CMRR values by precisely matching the input attenuators in a differential amplifier. The matching includes the DC attenuation and the capacitance which determines the AC attenuation.

Page 20: Safety
60 V Common Mode Differential Probes 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 21: Safe Operating Environment
User Manual CAUTION. To prevent damage to the equipment: Use only as specified. The probe is intended to be used only with compatible Teledyne LeCroy instruments. Use of the probe and/or the equipment it is connected to in a manner other than specified may impair the protection mechanisms. -
Page 22: 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 23: Freehand Probe Holder
User Manual 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 24: Connecting Tips
60 V Common Mode Differential Probes 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. - Page 25 User Manual 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 26 60 V Common Mode Differential Probes 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.
- Page 27 User Manual 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. The pogo pins at the far ends of the tip provide allowance for making contact with uneven surfaces.
- Page 28 60 V Common Mode Differential Probes 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 29: Using The Pcf-200 Deskew Fixture
User Manual 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. Use two BNC cables to connect a Fast Edge signal through the microstrip path you are using to the oscilloscope input channel. -
Page 30: Operating From The Oscilloscope
60 V Common Mode Differential Probes 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... - Page 31 User Manual 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 33: 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. -
