Operator’s Manual Safety Instructions This section contains instructions that must be observed to keep this oscilloscope accessory operating in a correct and safe condition. You are required to follow generally accepted safety procedures in addition to the precautions specified in this section. The overall safety of any system incorporating this accessory is the responsibility of the assembler of the system.
ADP30x Probe Precautions To avoid personal injury or damage to property, review and comply with the following safety precautions. Use product only as specified. Do not overload. To avoid electric shock or fire hazard, do not apply any potential that exceeds the maximum rating of the probe and/or the probe accessory, whichever is less. Connect and disconnect properly.
Operator’s Manual 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.

ADP30x Probe Voltage vs Frequency Derating Curve Input Voltage and Burn Limit vs. Frequency NOTE: The voltage derating curve provides the maximum voltage that can be applied to the probe inputs without risking damage to the probe. The Burn Limit is the voltage limit that should be used when the input leads are being hand-held. This limit is derived using the methodology described in EN 61010-031 section 6.3.1.2. WARNING.

Operator’s Manual Operation Connecting the Probe to the Test Instrument 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.
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.
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.
ADP30x Probe Probe Auto Zero Description PRx:AUTOZERO, PRx:AZ Command The PRx:AUTOZERO command initiates an auto zero cycle in the ADP30x probe to remove any offset drift. The probe input can remain connected to the test circuit during the auto zero cycle.
Operator’s Manual Probe Coupling PRx:COUPLING, PRx:CPL Command/query Description The PRx:COUPLING command selects the coupling mode of the ADP30x probe. The PRx:COUPLING? query returns the coupling mode of the selected channel.
ADP30x Probe Probe Offset Description PRx:OFFSET, PRx:OFST Command/Query When an ADP30x probe is connected to a channel, the OFFSET command sets the probe offset value. The maximum range and resolution is determined by the V/DIV setting. If an out-of-range value is entered, the differential probe will set the offset to the closest valid value, and the VAB bit (bit 2) in the STB register will be set. The OFFSET? query returns the offset voltage of the differential probe connected to the specified channel.
Operator’s Manual Probe Volts/div Description PRx:VOLT_DIV,PRx:VDIV Command/Query The PRx:VOLT_DIV command sets the vertical sensitivity at the ADP30x input. The effective gain of the differential probe is factored into the vertical sensitivity. The valid range of arguments is fixed by the probe type. If an outof-range value is entered, the oscilloscope will set the vertical sensitivity to the closest value and set the VAB bit (bit 2) in the STB register.
ADP30x Probe Maintenance Calibration Interval 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.
Operator’s Manual Returning a Defective Probe Contact your local Teledyne LeCroy service center for calibration or other service. If the product cannot be serviced on location, the service center will give you a Return Material Authorization (RMA) code and instruct you where to ship the product. All products returned to the factory must have an RMA. Return shipments must be prepaid. Teledyne LeCroy cannot accept COD or Collect shipments. We recommend air-freighting.
ADP30x Probe Replacement Parts The probe connection accessories and other common parts can be ordered through the regional customer care centers. Refer to the list below for Teledyne LeCroy part numbers. 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.
Operator’s Manual 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 Required 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.
ADP30x Probe 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.
Operator’s Manual Preliminary Procedure 1. Connect the ADP30x under test to the female end of the ProBus Extension Cable. Connect the male end of the ProBus Extension Cable to any channel of the oscilloscope. 2. Turn the oscilloscope on and allow at least 30 minutes warm-up time before performing the Certification Procedure. 3. Turn on the other test equipment and allow these to warm up for the time recommended by the manufacturer. 4.
ADP30x Probe 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: 1000 xMeasuredOutputVoltage − 1 x100 % Error = InputVolta ge 13. Record the answer to two significant places (±x.xx%) on line 13 in the Test Record. 14.
Operator’s Manual Performance Verification Test Record This record can be used to record the results of measurements made during the performance verification of the ADP300/ADP305 Active Differential Probe. Photocopy this page and record the results on the copy. File the completed record, as required by applicable internal quality procedures. The test record corresponds to the parameters tested in the performance verification procedure.

The output of the generator is measured with a DMM or oscilloscope in this procedure. Thus, the generator is not required to be calibrated.
Operator’s Manual Reference Information Differential Mode 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.
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.
