WARNING. High Voltage, risk of electric shock.

CAUTION. Potential for damage to probe or instrument it is connected to. 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.

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.

Precautions

To avoid personal injury or damage to probe or the instrument it is connected to, review and 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.

Comply with voltage derating curve. When measuring higher frequency signals, comply with the Input Voltage vs. Frequency Curve (see Figure 1).

922252-00 Rev A 1

HFP1500 High Frequency Probe

Do not overload. To avoid electric shock or damage to probe or instrument it is connected to, 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

The accessory is intended for indoor use and should be operated in a clean, dry environment. Before using this product, ensure that its operating environment is maintained within these parameters:

Temperature: 0° to 50° C.

Humidity: ≤ 80% max up to 31 °C, decreasing linearly to 45% max at 50 °C

Altitude: up to 2000 m (6562 feet)

Introduction

The 1.5 GHz HFP1500 is a small, high frequency active probe designed to meet today’s increasing demand for measurements on a variety of test points. With low input capacitance and high input resistance, circuit loading is minimized.

The HFP1500 can be used with Teledyne LeCroy’s WavePro™, Waverunner™ oscilloscopes, and LC series oscilloscopes with firmware version 8.7.0 or higher.

When the probe is used with any of these oscilloscopes, an AutoColor ID feature automatically illuminates the probe head in the default trace color of the channel to which the probe is connected, eliminating the need for color bands or other markers.

With the ProBus interface, the HFP1500 becomes an integral part of the oscilloscope. The probe can

be controlled from the oscilloscope’s front panel. The oscilloscope provides power to the probe, so

there is no need for a separate power supply or batteries.

Operator’s Manual

The small, low mass probe head is designed for ease of use and high performance.

The probe tip socket fits easily onto 0.025 inch square pins for direct access to test points. Several different adapters are available which connect directly in the probe socket.

The probe tip socket has a removable tip cartridge for easy replacement in case the probe socket gets damaged.

The ground socket will accept several different ground leads to provide a short ground path for high frequency performance.

The AutoColor ID consists of an LED inside the probe head which illuminates the probe body in the default trace color of the channel to which the probe is connected.

The AutoColor ID will only function when the probe is connected to a Teledyne LeCroy oscilloscope supplied with the ProBus interface and firmware version 8.7.0 or higher. The colors are correct when factory default color scheme 1 is selected.

Features and Accessories

The HFP1500 probe is provided with numerous features and accessories to make probing and connecting to different test points easier than ever.
