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.
Symbols
These symbols may appear on the ADP30x probe body or probe acccessories or
in this manual to alert you to important safety considerations.
Attend to the accompanying information to protect against personal injury or
damage. Do not proceed until conditions are fully understood and met.

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. To avoid electric shock or fire hazard, always
make the connections from the probe input leads to the probe accessory that
you intend to use before making any connections to a voltage source. Do not
connect or disconnect accessories to a votage source unless they are first
connected to the probe input leads.
Use only accessories compatible with the probe. Use only accessories that are
rated for the application. Substituting other accessories may create a potential
shock or burn hazard. Ensure connections between probe input leads and probe
accessories are secure before connecting them to a voltage source.
Comply with voltage derating curve. When measuring higher frequency signals,
comply with the Voltage vs. Frequency Derating Curve (see Page 6).
Observe all terminal ratings. To avoid electric shock or fire, do not use the
probe above the input limits shown on the probe as well as all accessories.
Do not remove probe casing. Removing the probe’s case or touching exposed
connections may result in electric shock.
Use only within operational environment listed. Do not use in wet or explosive
atmospheres. Keep product surfaces clean and dry.
Handle with care. Probe accessory tips are sharp. They can puncture skin or
cause other bodily injury if not handled properly.
Keep fingers behind the finger guard of the probe accessories.
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.

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
correspondingly rated probe accessories)
• ProBus Interface with Automatic Scaling
• Auto-Zeroing

Voltage vs Freque ncy 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. To avoid risk of electric shock or burn, comply with the burn
limits of the voltage vs. frequency derating curve when measuring high-
frequency signals with hand-held accessories.
