Introduction
The HVD series high-voltage active differential probes are safe, easy-to-use, and ideally
suited for power electronics applications where the reference potential is elevated from
ground. The probes feature:
•Differential voltage measurement capability in high common-mode environments
(up to 6kVrms)
•Exceptional common-mode rejection ratio (CMRR) across a broad frequency range
•Wide differential voltage range
•High offset voltage capability
•Guaranteed 1% DC and low frequency gain accuracy (up to 0.35% accuracy on
some models)
•AC or DC coupling (model dependent)
•ProBus interface with automatic scaling
•Auto Zero capabilities
The CMRR for the probes is exceptional out to very high frequencies. This greatly assists in
measuring signals in the noisy, high common-mode environments of power electronics.
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.
The maximum rated differential voltage specifications are provided for using each probe
within a wide differential voltage range. The probes will even display signals above the
maximum rated differential voltage, up to the maximum measurable differential voltage
before saturation limit, although the specifications cannot be guaranteed. Within this range,
the probe is operating below the saturation point of the amplifier, and very reasonable
results can be expected.
Note: HVD probes are fitted with detection circuits that will indicate when the differential or
common mode voltages are beyond the operating ranges of the probe. A warning will be
displayed in the oscilloscope message bar.
The probes are 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 Auto Zero capability permits further measurement
precision by allowing small offset drifts to be calibrated out of the measurement.

The ProBus interface makes the probe an integral part of the oscilloscope. Power is
provided to the probe through the interface, so there is no need for a separate power supply
or batteries. Attenuation may be either manually selected (HVD3220 only) or automatically
selected based on the oscilloscope gain range (V/div) setting, with the offset adjust unified
with that of the oscilloscope or locked to the maximum attenuation setting.
Maximum offset depends 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.
Compatibility
HVD3xxxA and HVD3220 probes are compatible with most Teledyne LeCroy oscilloscopes
equipped with the ProBus interface. For all compatible oscilloscope models, see:
teledynelecroy.com/probes/high-voltage-differential-probes
Required Firmware
Proper functioning of the HVD probes requires a minimum version of the MAUI™ firmware
to be installed on the oscilloscope:
•All HVD3xxxA probes require firmware version 8.5.1.0 or greater.
•HVD3220 probes require firmware version 9.4.x.x or greater.

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.
Symbols
These symbols appear on the probe and accessories or in this manual to alert you to
important safety considerations.
WARNING, HIGH VOLTAGE. Risk of electric shock or burn.
CAUTION of damage to probe or 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.
ESD CAUTION. Risk of Electrostatic Discharge (ESD) that can damage the probe or
instrument if anti-static measures are not taken.
Precautions
WARNING. To avoid personal injury or damage due to electric shock orfire:
Do not overload; observe all terminal ratings. Do not apply any potential that exceeds the
maximum rating of the probe and/or the probe accessory, whichever is less.
Comply with the Voltage vs. Frequency Derating curve when measuring higher frequency
signals.
Connect and disconnect properly. Always connect the probe input lead to the probe
accessories before connecting to a voltage source. Ensure the connections are secure
before applying voltage. Do not disconnect leads or accessories from a live circuit.
Keep the probe body and output cable away from the circuits being measured. Only
accessory tips are intended for contact with electrical sources.
Use only accessories compatible with the probe. Use only accessories that are rated for the
application. Substituting other accessories than those specified in this manual may create
a shock /burn hazard.

Keep fingers behind the finger guard of the probe accessories.
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. 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 bend cables excessively.
Use only within the operational environment listed. Do not use in wet or explosive
atmospheres.
Keep product surfaces clean and dry.
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.
