The HVD3000 and HVD3000A 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
• 1% DC and low frequency gain accuracy
• AC or DC coupling
• 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.
HVD3000A 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 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
HVD3000 and HVD3000A probes are compatible with most Teledyne LeCroy MAUI
oscilloscopes equipped with the ProBus interface. See the HVD3000 product page on our
website for all compatible oscilloscope models.
Some legacy oscilloscopes, such as WavePro 7000A and WaveSurfer XS, can be made
compatible with HVD3000 probes if upgraded to the Windows XP Professional operating
system and requisite firmware. Contact your regional service center regarding upgrades.
Required Firmware
Proper functioning of the HVD3000 and HVD3000A probes requires a minimum version of
the XStreamDSO™ firmware to be installed on the oscilloscope:
• The HVD310x probes require firmware version 7.4.x.x or greater.
• The HVD3206 and HVD3605 probes require firmware version 7.8.x.x or greater.

HVD3000 and HVD3000A probes have been designed for use with Teledyne LeCroy
oscilloscopes equipped with the ProBus interface. When you attach the probe to the
oscilloscope’s input connector, the instrument will:
• Recognize the probe
• Set the oscilloscope input termination to 1 MΩ
• Activate the probe control functions in the oscilloscope user interface
: For accurate measurements, connect the probe to the oscilloscope and allow it to
warm up for at least 20 minutes. When using HVD3000 probes, perform Auto Zero prior to
connecting probe leads to the DUT. HVD3000A probes may be connected to the DUT
during Auto Zero.
Connecting to the Test Circuit
Two inputs are available at the probe tip to connect the probe to a circuit under test. For
accurate measurements, both the + and – inputs must be connected to the test circuit.
Positive voltages applied to the + input (red) relative to the – input (black) will deflect the
oscilloscope trace toward the top of the screen.
To maintain the probe's high performance capability, exercise care when connecting the
probe. Increasing the parasitic capacitance or inductance in the input paths may introduce
a “ring” or slow the rise time of fast signals. Input leads that form a large loop area will pick
up any radiated electromagnetic field that passes through the loop and may induce noise
into the probe inputs. Because this signal will appear as a differential mode signal, the
probe’s common mode rejection will not remove it. This effect can be reduced by twisting
the input leads together to minimize the loop area.
To avoid electric shock or fire, maintain the input leads in good
condition. The leads have a jacket wear indicator that shows through when the
jacket is excessively worn. If the white "WEAR" indicator on the input leads is
visible, cease use and
High common mode rejection requires precise matching of the relative gain or attenuation
in the + and – input signal paths. Mismatches in additional parasitic capacitance,
inductance, delay, and a source impedance difference between the + and – signals will
lower the CMRR. Therefore, it is desirable to use the same length and type of wire and
connectors for both input connections. When possible, try to connect the inputs to points in
the circuit with approximately the same source impedance.
The probes may be stacked on one top of another during usage to conserve space. Since
the probe body generates heat, and the stacking reduces cooling, it is recommended that
ambient temperatures not exceed 30 degrees C while stacked probes are in operation. The
exceptional CMRR performance should prevent interference between probes when they are
stacked, but take care to separate the probe leads during operation.
To avoid electric shock or fire, keep the probe body and output cable
away
from the circuits being measured, as they cannot provide adequate protection
if they come in contact with electrical sources.
Operating with an 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 Probe dialog, which is added to the
oscilloscope's input channel dialogs when a probe is detected.
Channel setup dialog with Probe dialog behind it.
Probe dialog.
Probe Volts/Div and Attenuation
The front panel Volts/Div knob controls the oscilloscope’s scale factor and the probe’s
internal attenuation to give full available dynamic range. Some transition of the scale factor
will result in a change of attenuation.
Offset allows you to remove a DC bias voltage from the differential input signal while
maintaining DC coupling. This ensures that the probe will never be overdriven while a signal
is displayed on screen and prevents inaccurate measurements.
The total usable offset of the oscilloscope and probe system is a function of the
oscilloscope V/div setting and offset at that V/div setting, and the probe attenuation and
offset at that attenuation setting. Total maximum offset may be calculated as:
Oscilloscope Front End V/Div = (Probe and Oscilloscope) V/Div ÷ Probe_Attenuation
Once the oscilloscope front end V/div value is known, it is possible to know the maximum
oscilloscope offset available at this V/div setting either by referencing the oscilloscope
specifications or setting the maximum offset value on the oscilloscope for that V/div
setting. Maximum offset for the probe and oscilloscope combination can then be
calculated as:
Oscilloscope Positive Offset (at Oscilloscope Front End V/div) * Probe Attenuation– 10V
Oscilloscope Negative Offset (at Oscilloscope Front End V/div) * Probe Attenuation + 10V
In both cases, the maximum offset available cannot exceed the following:
Max Positive Offset (Probe and Oscilloscope together) =
Max Negative Offset (Probe and Oscilloscope together) =
X50 X100 X200 X500 X1000 X2000
: The offset values reported on oscilloscope channel descriptor boxes may deviate
slightly from expected values per the formulas above. The reported probe attenuation is a
"nominal" value and can deviate slightly from the actual value measured during calibration
and stored with the probe. The actual offset value reported uses the actual "as measured"
probe attenuation value. This provides for higher DC and low frequency gain accuracy than
would otherwise be possible.
In general, using offset to adjust a differential DC voltage on the screen is the preferred
method to measure transient signals in the presence of a larger DC voltage. The offset has
limits that will cause a signal that is beyond the linear operating range of the probe to go
off the screen, preventing measurement errors.
There are times, however, when it is convenient to use AC coupling to remove the DC
component of the measured signal from the measurement. Selecting AC10MΩ uses the
scope AC coupling at the probe output to remove any steady state value from the displayed
voltage. The maximum linear input voltage is as follows:
X50
<7 V/div
X100
<7 V/div
X200
<28 V/div
X500
>7 V/div
X1000
>7 V/div
X2000
>28 V/div
Because AC coupling is on the probe output, DC voltages beyond the probe’s linear
range will cause the amplifier to saturate and inaccurately render the displayed waveform.
Do not exceed the maximum linear input value when using AC coupling.
Bandwidth Limiting
To comply with various test standards used for quantifying output noise of power supplies,
the probe is capable of switching the bandwidth limit from Off (maximum bandwidth) to 20
MHz in the channel Vertical Adjust dialog.
Voltage Range
On oscilloscopes running XStreamDSO v.8.5.x.x and higher, there are two options as to how
the probe will set attenuation relative to the oscilloscope’s V/div setting:
will automatically raise the attenuation when the V/div setting is >7.9V/div or lower
the attenuation when the V/div is <7.9V/div. As a result the probe can automatically adjust
attenuation to properly view the input waveform.
locks the attenuation setting to the highest attenuation, regardless of the
V/div setting. Maintaining a high attenuation will allow small signals on a larger voltage
waveform to be accurately measured.

NOTE:
Overload Indicator (A models only)
On HVD3000A probes, an indication will appear in the oscilloscope message bar when the
differential or common mode voltages are beyond the operating ranges of the probe. Note
that the warning message below may trigger before any saturation occurs. It is designed to
guarantee that the system will not fail to indicate an overload.
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 HVD310x and HVD310xA
probes is 70 μV/°C (worst case) referred to the output. If the probe is set to 50x attenuation
and the ambient temperature changes by 10 °C, the DC offset drift could be as high as (70
μV/°C)(50)(10°C) = 35 mV referred to the probe tip. If measuring a 3 Vp-p signal, the DC
offset drift could be a little more than 1%. If the signal was 1400 Vp-p in 500x attenuation
mode, the DC offset drift at same ambient temperature could be as high as (70
μV/°C)(500)(10°C)= 350 mV due to the probe tip (although any offset accuracy error from
the oscilloscope itself would likely dominate the measurement).
Auto Zero is invoked manually from the Probe dialog that appears behind the Channel
setup dialog when the probe is connected to the oscilloscope.
When using HVD3000 probes, disconnect the probe from the test circuit before
performing Auto Zero. HVD3000A probes may remain connected during Auto Zero.
Always perform Auto Zero after the probe has been warmed-up (20 min. recommended).
Depending on the measurement accuracy desired and/or the change in the ambient
temperature where the probe is located, it may be necessary to perform Auto Zero more
often. If the probe is disconnected from the oscilloscope then re-connected, repeat Auto
Zero after a suitable warm-up time.
Auto Zero is disabled when AC coupling is selected.
Clean only the exterior surfaces of the device using a soft cloth or swab dampened with
water or 75% isopropyl alcohol solution. Do not use harsh chemicals or abrasive cleansers.
Dry the probe and accessories thoroughly before making any voltage measurements.
The probes are not waterproof. Under no circumstances submerge the
probe in liquid or allow moisture to penetrate it.
Calibration Interval
This probe has no adjustments. The recommended calibration interval is one year. A
Performance Verification Procedure is included in this manual.
Service Strategy
HVD3000 and HVD3000A probes utilize fine-pitch surface mount devices. It is, therefore,
impractical to attempt repair in the field. Defective probes must be returned to a
Do not remove the covers. Refer all servicing to qualified personnel. A
defective probe under warranty will be replaced with a factory refurbished probe.
A probe that is not under warranty can be exchanged for a factory refurbished probe for a
modest fee. Replacement probes are factory repaired, inspected, and calibrated to the
same standards as a new product. You must return the defective probe in order to receive

The ideal differential probe/amplifier would sense and amplify only the differential mode
voltage component and reject the entire common mode voltage component. Real
differential amplifiers are not perfect, and a small portion of the common mode voltage
component appears at the output.
Common Mode Rejection Ratio (CMRR) is the measure of how much the amplifier rejects
the common mode voltage component. CMRR is equal to the differential mode gain (or
normal gain) divided by the common mode gain. Common mode gain is equal to the output
voltage divided by the input voltage when both inputs are driven by only the common mode
signal. CMRR can be expressed as a ratio (e.g., 10,000:1) or implicitly in dB (e.g., 80 dB).
Higher numbers indicate greater rejection (better performance).
The first order term determining the CMRR is the relative gain matching between the + and
– input paths. 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. As the frequency of the common mode component
increases, the effects of stray parasitic capacitance and inductance in determining the AC
component become more pronounced. The CMRR becomes smaller as the frequency
increases. Therefore, the CMRR is usually specified in a graph of CMRR versus common
mode frequency.
The common mode frequency in these graphs is assumed to be sinusoidal. In real life
applications, the common mode signal is seldom a pure sine wave. Signals with pulse wave
shapes contain frequency components much higher than the repetition rate may suggest.
This makes it very difficult to predict actual performance in the application for CMRRversus- frequency graphs. The practical application of these graphs is to compare the
relative common mode rejection performance between different probes and amplifiers.
Differential probes sense the voltage difference that appears between the + and – inputs.
This is referred to as the Differential or Normal 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 as:
Differential Mode Range and Common Mode Range
Differential Mode range is the maximum signal that can be applied between the + and
inputs without overloading the amplifier, which otherwise would result in clipping or
distorting of the waveform measured by the oscilloscope.
The Common Mode Range is the maximum voltage with respect to earth ground that can
be applied to either input. Exceeding the common mode range can result in unpredictable
measurements. Because the Common Mode signal is normally rejected, and not displayed
on the oscilloscope, be careful to avoid accidentally exceeding the common mode range.
Measurement Category III (CAT III) applies to test and measuring circuits connected to the
distribution part of the building’s low-voltage mains installation.
Measurement Category II (CAT II) applies to test and measuring circuits connected directly
to utilization points (socket outlets and similar points) of the low-voltage mains installation.
Measurement Category I (CAT I) applies to test and measurement circuits that are not
intended to be directly connected to the mains supply.
Pollution Degree 2 refers to an operating environment where normally only dry nonconductive pollution occurs. Conductivity caused by temporary condensation should be
expected.

Measurement Category III (CAT III) applies to test and measuring circuits connected to the
distribution part of the building’s low-voltage mains installation.
Measurement Category II (CAT II) applies to test and measuring circuits connected directly
to utilization points (socket outlets and similar points) of the low-voltage mains installation.
No Rated Measurement Category applies to other circuits that are not directly connected to
the mains supply.
Pollution Degree 2 refers to an operating environment where normally only dry nonconductive pollution occurs. Conductivity caused by temporary condensation should be
expected.
The 2015 version of the standard eliminates the Measurement Category I (CAT I)
rating for test and measuring circuits that are not intended to be directly connected to the
mains supply. However, this change in rating designation does not reduce the
measurement capability or the level of protection offered by the new probe design when
compared to the probes that were originally certified per the 2008 version of the standard.
