Introduction

The ADP30x family of high voltage active differential probes is safe, easy-to-use,
and ideally suited for power measurements.

The 20 MHz ADP300 is perfect for troubleshooting low frequency power circuits,
and other circuits where the reference potential is elevated from ground or the
location of ground is unknown.

The 100 MHz ADP305 is designed for measuring high-speed floating voltages
found in today’s power electronics, like switching power supplies.

With the ProBus interface, the ADP30x becomes an integral part of the
oscilloscope. For the ADP305, the attenuation, offset, and bandwidth limit are all
controlled from the oscilloscope’s front panel or by means of remote control
commands. This means that the complete measurement setup can be saved and
recalled by the oscilloscope and all measurement values will be correct. The
oscilloscope provides power to the probe, so there is no need to worry about a
separate power supply or changing batteries.

The sensitivity of the ADP300 ranges from 1 V/div to 350 V/div; and the
sensitivity for the ADP305 ranges from 200 mV/div to 350 V/div.

Attenuation is automatically selected by the oscilloscope to either ÷100 or
÷1000.

Key Benefits

• True Differential Measurements

• EN 61010-031 1000 V CAT III Safety Compliance (when used with

Operation

Connecting the Pr obe to the Test Inst rument

The ADP30x series of probes has been designed for use with Teledyne LeCroy
oscilloscopes equipped with the ProBus interface. When you attach the probe
output connector to the scope’s input connector, the scope will recognize the
probe, set the scope input termination to 1 MΩ, and activate the probe control
functions in the user interface.

Connecting the Probe to the Test Circuit

The ADP30x series of probes is 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, the + and – inputs both must always be
connected to the test circuit. Positive voltages applied to the + input (red)
relative to the – input (blue) will deflect the oscilloscope trace toward the top of
the screen.

To maintain the high performance capability of the probe in measurement
applications, care must be exercised in connecting the probe to the test circuit.
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 greatly 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.

ADP30x Probe

Operation with a Teledyne LeCroy Oscilloscope

When the ADP30x 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.

Through the oscilloscope software, the probe’s internal attenuation and offset
can be conveniently controlled through the oscilloscope’s user interface.

Turning the V
probe’s internal attenuation to give full available dynamic range from 1 V/div to
350 V/div for the ADP300, and from 200 mV/div to 350 V/div for the ADP305.
Some of the transition of the scale factor will result in a change of attenuation.

OLTS/DIV knob will control the oscilloscope’s scale factor and the

Smart Offset

The ADP30x has offset capability. This allows you to remove a DC bias voltage
from the differential input signal while maintaining DC coupling.

The offset range of the probe is a function of the oscilloscope’s sensitivity and
the probe’s attenuation. This ensures that the probe will never be overdriven on
screen. In addition, it will prevent the oscilloscope from being overdriven and
getting inaccurate measurements.

Bandwidth Limit (ADP305 only)

To comply with various test standards used for quantifying output noise of
power supplies, the ADP305 is capable of switching the bandwidth limit from Off
(maximum bandwidth) to 20 MHz in the channel Vertical Adjust dialog.

Auto Zero

The ADP30x incorporates an Auto Zero function to remove the DC offset from
the Differential Amplifier’s output. Auto Zero must be invoked by the user. You
may do this even while the probe is connected to a live circuit.

After several minutes of warm-up, or when the probe is exposed to a large shift
in ambient temperature, some DC offset drift may occur from thermal effects in
the amplifier. To initiate an Auto Zero cycle, select "AUTO ZERO" in the
oscilloscope’s user interface. During an Auto Zero cycle the oscilloscope will
automatically disconnect the ADP30x inputs from the circuit under test, perform
the auto zero function, and reconnect the inputs.

Operator’s Manual

Remote Control Commands

When attached to a Teledyne LeCroy oscilloscope equipped with ProBus
interface, the ADP30x Active Differential Probe can be remotely controlled,
along with the other oscilloscope functions. The control interface can be either
the RS-232 or IEE-488 (GPIB) buses. The commands that control the probe are
described below. The text for the command description is formatted in a style
consistent with the oscilloscope command description contained in the Teledyne
LeCroy Digital Oscilloscopes Remote Control Manual supplied with the
oscilloscope. Please refer to this manual for additional information on the
remote control buses and the conventions used in the command descriptions.

The commands begin with the "PRx:" prefix, where "x" is the channel that the
ADP30x is connected to. These commands are similar to the channel commands
that use the prefix "Cx:". The difference is that the "PRx:" form refers to the
probe tip, whereas the "Cx:" form refers to the oscilloscope input connector.
For example, "PRx:VDIV" sets the Volts per division at the probe tip, while
"Cx:VDIV" sets the Volts per division at the BNC input connector, without
factoring the gain or attenuation factor of ADP30x probe. The "PRx:" form of
these commands are only active when the ADP30x probe is connected to the
selected channel. An error will result when an ADP30x specific command is sent
to the oscilloscope without a differential probe connected to the selected
channel.

Command List

PRx:AUTOZERO Initiates an auto zero cycle in the probe.

PRx:BWL Selects the probe upper bandwidth limit.
PRx:COUPLING Selects the input coupling of the probe.
PRx:OFFSET Selects the probe offset voltage.
PRx:VDIV Selects the vertical scale factor of the

probe/oscilloscope system.

Maintenance

Calibration Int erval

This probe has no adjustments. The recommended calibration interval is one
year. (A Performance Verification Procedure is included in this manual.)

Cleaning

Clean only the exterior surfaces of the probe using a soft cloth or swab
dampened with 75% isopropyl alcohol. Do not use harsh chemicals or abrasive
elements. Probe is not water proof. Under no circumstances submerge the
probe or allow moisture to penetrate it.

Service Strategy

The ADP30x series 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. 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.

WARNING No user serviceable components inside. Do not remove
covers. Refer servicing to qualified personnel.

Troubleshooting

If the probe is not operating properly the problem may be the way in which it is
used. Before assuming that the probe is defective, perform the following
troubleshooting procedures:

1. For Teledyne LeCroy LT and LC series scopes, verify that the firmware

version is 8.5 or higher.

2. Waveform is inverted. — Make sure that the + lead (Red) is connected to

the proper test point.

3. No DC. — Make sure that the attachment accessory is completely plugged

onto the lead.

4. No output signal. — Make sure that DC coupling is selected.

Functional Test

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.

Test Equipment Requi red

Other than a Teledyne LeCroy oscilloscope, no special test equipment is required
for the functional test.

Test procedure

1. Connect the ADP300 or ADP305 to any vertical channel on the oscilloscope.

2. Select the channel to which the probe is connected.

3. Press the A

4. If necessary, adjust the O

UTO ZERO button in the user interface menu.

FFSET to 0.000 V.

5. Using accessory clips, attach the Red clip to the + CAL out and the Blue 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 A

UTOSETUP.

7. Set the sensitivity of the probe to 1 V/div.

8. Set the CAL output to 1 V

9. Verify that the displayed square wave is 1 V

Performance Verification

This procedure can be used to verify the warranted characteristics of the
ADP30x series Active Differential Probes.

If the product does not meet specifications, it should be returned to a Teledyne
LeCroy service center. There are no user accessible adjustments, so there is no
adjustment procedure.

Test Equipment Requi red

The following table lists the test equipment and accessories (or their
equivalents) that are required for performance verification of the ADP30x Active
Differential 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.

Procedure

1. Set the function generator to sine wave, 70 Hz, and an output voltage of

approximately 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 under test 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 (Blue) 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 1000 and

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:

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 100 and

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.

18. Record the answer to two significant places (±x.xx%) on line 18 in the Test

Record.

19. Verify that the error is ≤ 2.00%.

Differential M ode and Common Mode

Differential amplifiers amplify the voltage difference that appears between the +
input and – input. This voltage is referred to as the Differential Mode or Normal
Mode voltage. The voltage component that is referenced to earth and is
identical on both inputs is rejected by the amplifier. This voltage is referred to as
the Common Mode voltage and can be expressed as:

Differential M ode 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 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, you need to be careful
to avoid accidentally exceeding the common mode range.

Common Mode Rejection Ratio

The ideal differential amplifier would amplify only the differential mode voltage
component and reject all of the common mode voltage component. Real
differential amplifiers are not perfect, so a small portion of the common mode
voltage component appears at the output. Common Mode Rejection Ratio
(CMRR) is the measure of how well 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. The 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
implicitly in dB (e.g., 80 dB). The higher the number the greater the rejection the
better the performance.

923079-00 Rev A 27

000:1) or

ADP30x Probe

The first order term that determines the CMRR is the relative gain matching
between the + and – input paths. To obtain high CMRR values, the input
attenuators in a differential amplifier are precisely matched to each other. This
matching includes the DC attenuation as well as the capacitance that 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 becomes more pronounced. The CMRR becomes
smaller as the frequency increases. Hence, 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. As such, it is very difficult to predict actual
performance in the application for CMRR versus frequency graphs. The practical
application of these graphs is to compare the relative common mode rejection
performance between different amplifiers.
