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 probe body or in this manual to alert you to important safety
considerations.
HIGH VOLTAGE, risk of electric shock.
CAUTION of Potential damage to probe or instrument it is connected to, or
WARNING of potential bodily injury. Attend to the accompanying
information to protect against personal injury or damage. Do not proceed
until conditions are fully understood and met.
ELECTROSTATIC DISCHARGE (ESD) HAZARD. The probe is susceptible to
damage if anti-static measures are not taken.
DOUBLE INSULATION
PROTECTIVE (EARTH) TERMINAL
Precautions
To avoid personal injury, or damage to the probe or test instrument, comply with the following
safety precautions.
Use product only as specified.
Connect and disconnect properly. Connect probe to the measurement instrument before
connecting the test leads to a circuit/signal being tested.
Use only accessories compatible with the probe. Use only accessories that are rated for the
application. Ensure connections between probe input leads and probe accessories are secure
before connecting them to a voltage source.

Do not overload. To avoid electric shock, do not apply any potential that exceeds the maximum
rating of the probe and/or the probe accessory, whichever is less. Observe all terminal ratings of
the instrument before connecting the probe.
Be careful not to damage the insulation surface when making measurements.
Use only within operational environment listed. Do not use in wet or explosive atmospheres.
Keep product surfaces clean and dry. Use indoors only.
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.
Operating Environment
Only use the product within this operating environment:
Temperature: 0° to 50° C
Humidity: Maximum relative humidity 90 % for temperatures up to 31° C decreasing linearly to
50% relative humidity at 40° C
Altitude: Up to 10,000 ft (3,048 m)

Overview
Description
The AP034 is a wide band differential active probe. The probe features low noise, low input
capacitance, high common mode rejection, and FET-buffered inputs in the probe head. User
selectable attenuation and offset give the probe flexibility to measure a large range of signal
amplitudes. Plug-on attenuator and AC coupling accessories further extend the application range.
Interconnect accessories included allow connection to surface mount and through-hole
components with minimal signal degradation. The input receptacles in the probe head are
compatible with standard 0.025 in. (0.635 mm) square pins. This provides a convenient low cost
method of creating device characterization test fixtures.
The probe is powered directly from a Teledyne LeCroy oscilloscope through the ProBus® interface.
The ProBus interface also allows local control of the probe through the oscilloscope user interface
and remote control through the interface buses, (GPIB, RS-232). The optional ADPPS power supply
allows the AP034 to be used with other instruments such as spectrum analyzers, network
analyzers, and oscilloscopes without ProBus interface.
Applications
The AP034 is ideal for acquiring high speed differential signals such as those found in disk drive
read channels, differential LAN, video, etc. It can also be used with spectrum analyzers to acquire
signals in some RF systems (for example, balanced IF mixers in hand held cellular telephones). The
high impedance characteristics of both inputs allow the probe to be used as a FET probe to make
single-ended measurements in digital systems without introducing a ground loop, as a conventional
FET probe would.

Oscilloscope Software Compatibility
For full control functionality of the probe, Teledyne LeCroy LC series oscilloscopes must have
software version 8.1.0 or higher loaded; all X-Stream oscilloscopes are compatible. The software
version installed in a Teledyne LeCroy oscilloscope can be verified by pressing the SHOW STATUS
button on the front panel (where available), then selecting the System menu choice. The probe can
be used with earlier versions of software; however, probe offset can only be controlled through the
buttons on the probe body. Also, the scale factor will be displayed incorrectly in some modes.
For information on upgrading the software in your oscilloscope, see
teledynelecroy.com/support/softwaredownload, or contact your local Teledyne LeCroy
representative.
