Safety
Follow these instructions to keep the probe operating 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.
Symbols
These symbols appear on the probe or in documentation to alert you to important safety
considerations.
CAUTION of damage to instrument, or WARNING of hazard to health. Attend to the
accompanying information to protect against personal injury or damage. Do not
proceed until conditions are fully understood and met.
HIGH VOLTAGE WARNING. Risk of electric shock.
ESD CAUTION. Risk of electrostatic discharge (ESD) that can damage the instrument if
anti-static measures are not taken.
Double Insulation
Measurement Ground
Precautions
Avoid personal injury or damage to your equipment by complying with the following safety
precautions:
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.
Do not overload; observe all ratings. To avoid electric shock or fire, do not apply any potential
that exceeds the maximum rating of the probe and/or the probe accessory, whichever is less.
Observe all terminal ratings.

HVD3102 and HVD3106 High-Voltage Differential Probes
Connect and disconnect properly. Always make the connections from the probe input leads to
the probe accessory that you intend to use before making any connections to a voltage source.
Do not connect accessories to (or disconnect from) a voltage source unless they are first
connected to the probe input leads. Avoid damaging cables through excessive bending.
Use only accessories compatible with the probe. Use only accessories that are rated for the
application. Substituting other accessories (except those specified in this manual) may create a
shock or burn hazard. Ensure the connections between probe input leads and probe
accessories are secure before connecting them to a voltage source.
Comply with the voltage derating curve. When measuring higher frequency signals, comply
with the Voltage vs. Frequency Derating Curve.
Use only within the operational environment listed. Do not use in wet or explosive
atmospheres.
Do not remove the probe's casing. Touching exposed connections may result in electric
shock.
Keep product surfaces clean and dry.
Handle with care. Probe accessory tips are sharp. They can puncture skin or cause other bodily
injury if not handled properly.
Keep fingers behind the finger guard of the probe accessories.
Do not operate with suspected failures. Before each use, inspect the probe and accessories
for any damage such as tears or other defects in the probe body, cable jacket, accessories, etc.
If any part is damaged, cease operation immediately and sequester the probe from inadvertent
use.

Operator's Manual
Introduction
The HVD3102 and 3106 high-voltage active differential probes are safe, easy-to-use, and ideally
suited for power electronics measurements. The probes feature:
lDifferential voltage measurement capability in high common-mode (up to 1000Vrms)
environments.
lExceptional common-mode rejection ratio (CMRR) across a broad frequency range
lWide differential voltage range – 1500Vpeak rated and 2000Vpeak before amplifier
saturation to permit capture of short duration overshoots
lHigh offset capability at both 50x and 500x attenuation settings provides maximum
flexibility for capturing gate drive and control signals floating on a 1000Vdc bus
l1% DC and low frequency gain accuracy
lProBus interface with automatic scaling
lAuto Zero capabilities
The HVD3102 probe (25 MHz, 1000Vrms) and HVD3106 probe (120 MHz, 1000Vrms) are ideal
for power electronics applications, where the reference potential is elevated from ground. Each
probe is supplied with a complete set of lead accessories and a soft accessory case. The main
differences between the two probes is the probe bandwidth (25 MHz vs. 120 MHz).
The CMRR for the probes is exceptional out to very high frequencies. This greatly assists in
measurement of signals in the noisy, high common-mode environments common to power
electronics. The high CMRR combined with low probe noise and high offset capability makes the
probes capable of measuring very small control signals floating on high common-mode
voltages.
Probe specifications are provided for using the probe within a 1500Vpeak differential voltage
range. However, the probe can be safely operated above this range. Up to 2000Vpeak, the probe
will display the signal, but the probe specifications cannot be guaranteed. However, in this
range, the probe is operating below the saturation point of the amplifier, and very reasonable
results can be expected. The V/div range for each probe can be set up to 400V/div (3200Vp-p
displayed over all 8 vertical oscilloscope grid divisions).

HVD3102 and HVD3106 High-Voltage Differential Probes
The probe is calibrated for high precision measurements to within 1% at DC to low frequency
(~10 kHz). This provides for high accuracy of top and base voltage levels of pulse-width
modulated signals. The AutoZero capability permits further measurement precision by allowing
small offset drifts to be calibrated out of the measurement.
With the ProBus interface, the HVD310x becomes an integral part of the oscilloscope. Power is
provided to the probe through the ProBus interface, so there is no need for a separate power
supply or batteries. Attenuation (50x or 500x) is automatically selected based on oscilloscope
gain range (V/div) setting and the offset adjust is unified with that of the oscilloscope. The
sensitivity of the HVD31xx ranges from 100 mV/Div to 400 V/Div, with the maximum available
offset dependent on the V/div setting and the oscilloscope model. In general, Teledyne LeCroy
12-bit High Resolution Oscilloscopes (HRO) and HD4096 High Definition Oscilloscopes (HDO)
provide the most offset capability over the widest range of V/div settings.
Requirements
The HVD3102 and HVD3106 probes are compatible with any Teledyne LeCroy oscilloscope
equipped with the ProBus interface and XStream software version 7.4 or greater.
