HVD3102 and HVD3106 High-Voltage Differential Probes
Introduction
The HVD3102 and HVD3106 high-voltage active differential probes are safe, easy-to-use, and
ideally suited for power electronics measurements. The probes feature:

Differential voltage measurement capability in high common-mode (up to 1000Vrms)
environments.
Exceptional common-mode rejection ratio (CMRR) across a broad frequency range
Wide differential voltage range – 1500Vpeak rated and 2000Vpeak before amplifier
saturation to permit capture of short duration overshoots
High offset capability at both 50x and 500x attenuation settings provides maximum
flexibility for capturing gate drive and control signals floating on a 1000Vdc bus

1% DC and low frequency gain accuracy

Auto Zero capabilities
The HVD3102 (25 MHz, 1000Vrms), HVD3106 (120 MHz, 1000Vrms), and HVD3106-6M (80
MHz, 1000Vrms) probes 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 difference amng probes is the probe
bandwidth.
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).
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.
The HVD310x probes are compatible with any Teledyne LeCroy oscilloscope equipped with the
ProBus interface and XStream software version 7.4 or greater.
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 HVD310x 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.

HVD3102 and HVD3106 High-Voltage Differential Probes
Common Mode Rejection Ratio
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 CMRR-versusfrequency graphs. The practical application of these graphs is to compare the relative common
mode rejection performance between different probes and amplifiers.

Input Voltage vs. Frequency and Burn Limit
The Maximum Input Voltage curve (solid line on graph) shows the maximum voltage that can
be applied to the probe inputs without risking damage to the probe. The lower Burn Limit curve
(dashed line on graph) shows the maximum voltage that can be applied to the probe inputs
while the operator is handling the inputs. Handling the inputs while connecting the probe to
active signals above this burn limit could result in injury to the operator.
WARNING. To avoid risk of electric shock or fire, comply with the burn limits of the
derating curve when measuring high-frequency signals with hand-held accessories.
Do not exceed the voltage or category rating of the probe or accessories (whichever
is less). Keep your fingers behind the finger guard of the probe. Keep the output
cable away from the circuits being measured. Use only the specified accessories.

Operator's Manual
Differential Mode and Common Mode
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.

HVD3102 and HVD3106 High-Voltage Differential Probes
Operation
Connecting to the Test Instrument
The HVD310x probes have been designed for use with Teledyne LeCroy oscilloscopes
equipped with the ProBus interface. When you attach the probe output connector to the
oscilloscope’s input connector, the instrument will:
l
Recognize the probe
l
Set the oscilloscope input termination to 1 MΩ
l
Activate the probe control functions in the oscilloscope user interface.
NOTE: To ensure accurate measurements, connect the probe to the oscilloscope and allow to
warm up for at least 20 minutes. Then, perform an Auto Zero prior to connecting the probe to
the device under test.
Connecting to the Test Circuit
The HVD310x probes are ideally suited for applications where no ground is available or where
the location of a ground connection is unknown.
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 high performance capability of the probe in measurement applications,
exercise care when connecting the probe. Increasing the parasitic capacitance or inductance in
the input paths may introduce a “ring” or may 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.
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 common
mode rejection ratio. 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.
To minimize the amount of bench space occupied, the probes may be stacked on one top of
another during usage. Since the probe body generates heat, and the stacking reduces cooling,
it is recommended that ambient temperatures not exceed 30 degrees C while the probes are
16
Operator's Manual
stacked and in operation. The exceptional CMRR performance of the probe should prevent
interference between probes when they are stacked, but care should be taken to separate the
probe leads during operation.
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 from 100 mV/Div to 400 V/Div. Some transition
of the scale factor will result in a change of attenuation.
Offset
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, oscilloscope offset at that V/div setting, probe attenuation, and probe offset at
that attenuation setting, and this total maximum offset may be calculated.
First, it is necessary to know the oscilloscope front end V/div setting with the probe
17
HVD3102 and HVD3106 High-Voltage Differential Probes
connected. This may be calculated as follows:
Oscilloscope Front End V/Div = (Probe and Oscilloscope) V/Div ÷ Probe_Attenuation
Once the oscilloscope front end V/div value is known, then it is possible to know the maximum
offset available in the oscilloscope 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.
Then, the maximum offset available with the probe and oscilloscope combination can be
calculated as:
Max Positive Offset Available
Max Positive Offset (Probe and Oscilloscope together) =
Oscilloscope Positive Offset (at Oscilloscope Front End V/div) * Probe Attenuation – 10V
Max Negative Offset Available
Max Negative Offset (Probe and Oscilloscope together) =
Oscilloscope Negative Offset (at Oscilloscope Front End V/div) * Probe Attenuation + 10V
In both cases, the maximum offset available cannot exceed the HVD3102 maximum offsets of
±150V at 100x attenuation and ±1500V at 1000x attenuation or the HVD3106 maximum
offsets of ±150V at 50x attenuation and ±1500V at 500x attenuation.
NOTE: The offset values reported in the oscilloscope's channel descriptor box may deviate
slightly from expected values, based on calculations 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.
AC Coupling
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.
Note that, since this AC coupling is on the probe output, DC voltages beyond the linear range
of the probe will cause the amplifier to saturate and make the displayed waveform inaccurate.
It is important not to exceed the maximum linear input values when using AC coupling. The
maximum linear input voltage is 2000V (peak) when the probe is in 500x or 1000x attenuation
(>7V/div), and 200V (peak) when the probe is in 50x or 100x attenuation (<7V/div).
18
Operator's Manual
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.
Auto Zero
Auto Zero corrects for DC offset drifts that naturally occur from thermal effects in the
amplifier. The probe incorporates Auto Zero capability to remove the DC offset from the
probe's differential amplifier output to improve the measurement accuracy. Auto Zero is
invoked manually from the Probe dialog that appears behind the Channel setup dialog when
the probe is connected to the oscilloscope.
NOTE: Remove the probe from the test circuit before performing Auto Zero.
Always perform Auto Zero after probe warm-up (recommended warm-up time is 20 minutes).
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 and re-connected, repeat Auto Zero after a
suitable warm-up time.
For example, the DC offset drift of the probe 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, then the DC
offset drive could be as high as (70 μV/°C)(50)(10°C) = 35mV (referenced to the probe tip). If
the probe is being used to measure a 3Vp-p signal, then the DC offset drift in this case could be
a little more than 1%. If the signal measured was 1400Vp-p in 500x attenuation mode, then the
DC offset (in the same ambient temperature condition) could be as high as (70 μV/°C)(500)
(10°C) = 350 mV due to the probe tip, but any offset accuracy error from the oscilloscope itself
would likely dominate the measurement.
Auto Zero is disabled when AC coupling is selected.

Functional Test Procedure
This procedure should be performed to confirm the basic operation of the probe, or to aid in
determining the source of a problem, rather than to verify the accuracy of the probe. You can
perform the Functional Test without removing the probe covers.
Other than a Teledyne LeCroy oscilloscope, no special test equipment is required for the
functional test.
1. Connect the HVD3102/HVD3106 to any vertical channel on the oscilloscope.
2. Select the channel to which the probe is connected.
3. Touch AUTO ZERO on the HVD310x probe dialog.
4. If necessary, adjust the OFFSET to 0.000 V.
5. Using accessory clips, attach the red clip to the + CAL out and the black clip to the ground
post of the CAL out signal. For oscilloscopes with the CAL signal on a BNC connector, a
BNC-to-Banana adapter (e.g., Pomona model 1296) may be used.
6. Press AUTOSETUP.
7. Set the sensitivity of the probe to 1 V/Div.
8. Set the CAL output to 1 Vp-p square wave.
9. Verify that the displayed square wave is 1 Vp-p centered at +0.5 V.
10. Reverse the accessory leads on CAL out and verify that the displayed square wave is still 1
V, but is now centered at –0.5 V.
11. Change the COUPLING on the channel setup dialog to Grounded to verify that the signal
disappears and that the trace is still centered on the screen.
12. Verify that the probe attenuation shows x100 for HVD3102 or x50 for HVD3106.
13. Set the VOLTS/DIV to 100 V.
14. Verify that the probe attenuation now shows x1K for HVD3102 or x500 for HVD3106.

Performance Verification
This procedure can be used to verify the warranted characteristics of the HVD310x probe. If
the product does not meet specifications, it should be returned to a Teledyne LeCroy service
center. As there are no user accessible adjustments, there is no adjustment procedure.
Required Equipment
The following table lists the test equipment and accessories (or their equivalents) that are
required for performance verification of the probe. This procedure is designed to minimize the
number of calibrated test instruments required. Because the input and output connector
types may vary on different brands and models of test instruments, additional adapters or
cables may be required. Only the parameters listed in boldface in the "Minimum requirements"
column must be calibrated to the accuracy indicated.

7.00 V rms (into a high impedance output).
2. Set the DMM to measure AC Volts.
3. Connect the function generator output to the DMM, using a BNC cable and a female BNC
to dual banana plug adapter.
4. Adjust the function generator output voltage until the DMM reads 7.000 V ±0.01 V.
5. Record the DMM reading to 1 mV resolution in the Test Record.
6. Disconnect the BNC cable from the function generator and from the BNC-to-banana plug
adapter on the DMM. (Leave the banana plug adapter connected to the DMM).
7. Connect the BNC connector from the probe extender cable to the BNC-to-banana plug
adapter on the DMM.
8. Connect the insulated banana plug adapter to the function generator.
9. Using the insulated banana couplers, connect the positive lead (red) of the probe under
test to the positive output of the BNC-to-banana plug adapter and the negative lead (black)
to the negative or return output.
10. Set the oscilloscope scale factor to 20 V/Div.
11. Record the DMM reading to 0.01 mV resolution in the Test Record.
12. Multiply the measured output voltage recorded in step 11 by the actual probe attenuation
factor, then divide this number by the function generator output voltage (probe input
voltage) recorded in step 5. Subtract 1 from this number and multiply the result by 100 to
get the error in percent:
NOTE: The actual probe attentuation can be found by using the XStream Browser. Choose

File > Exit to show the oscilloscope desktop, then double-click the XStream Browser icon.
In the locator field, enter the path "app.Acquisition.C1.InputB.HVD310x" (where x is your
probe model number). The value is shown next to PrAttenuation.
13. Record the answer to two significant places (± x.xx%) on line 13 in the Test Record.
14. Verify that the error ≤ 1.00%.
15. Decrease the oscilloscope scale factor to 5 V/Div.
16. Record the DMM reading to 0.01 mV resolution in the Test Record.
17. Multiply the measured output voltage recorded in step 16 by the actual probe attenuation
factor, then divide this number by the function generator output voltage (probe input
voltage) recorded in step 5. Subtract 1 from this number and multiply the result by 100 to
get the error in percent.
NOTE: Recheck the actual probe attentuation in the XStream Browser, as it will now be a
different value than in step 12.
18. Record the answer to two significant places (±x.xx%) on line 18 in the Test Record.
19. Verify that the error is ≤ 1.00%.
This completes the Performance Verification Procedure. Complete and file the Test Record, as
required to support your internal calibration procedure. If the criteria in steps 14 or 19 are not
met, contact your local Teledyne LeCroy service center.
Test Record
Permission is granted to photocopy the following page and record the results of the

Maintenance
Cleaning
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.
CAUTION. The HVD3102/HVD3106 is not water proof. Under no circumstances
submerge the probe 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
The HVD3102/HVD3106 probe utilizes 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. A probe
that is not under warranty can be exchanged for a factory refurbished probe for a modest fee.
You must return the defective probe in order to receive credit for the probe core.
Replacement Parts
The probe accessories can be ordered as a replacement kit, PK-HV-001, through your local
sales office, and individual probe accessory tips (pair 1 ea. red/black) can be purchased
through the regional customer care centers listed at the back of this manual.Defective probes
can be replaced on an exchange basis. Replacement probes are factory repaired, inspected,
and calibrated to the same standards as a new product. In order to obtain a replacement
probe, you must return the defective probe. Return the probe to your regional customer care
center.
