Safety Information

1 Safety Information

OPERATOR SAFETY

To avoid personal injury and to prevent damage to the probe or any products connected to it,
review the following safety precautions. To avoid potential hazards, use the probe only as speci­fied.

Warning

For indoor use only. To avoid fire or personal injury, comply with the following:

Connect probe to the measurement instrument before connecting test leads to a voltage source.

Do not disconnect probe from instrument while test leads are connected to a voltage source.

Use of the probe and/or the oscilloscope it is connected to in a manner other than that specified
may impair the protection mechanisms.

Do not apply a potential to any input that exceeds the maximum rating of that input. (Section 9,
Specifications.)

When measuring high frequency signals, be sure to comply with the voltage vs. frequency derating
curve. (Section 9, Specifications.)

Do not use in wet or explosive atmospheres.

Do not use the probe if any part is damaged. All maintenance should be referred to qualified ser­vice personnel.

Overview

2 Overview

PRODUCT DESCRIPTION

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 LeCroy’s WavePro™, Waverunner™ and LC series oscilloscope
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.

When used in combination with an ADPPS power supply, the HFP1500 probe can be used with
non-LeCroy instruments. (See Section 4 for detailed operation with an ADPPS adapter).

KEY BENEFITS

• High frequency performance

• Low input capacitance

• Wide dynamic range

• ProBus interface

• AutoColor ID feature matches the probe color to the oscilloscope’s default trace color

• Five interchangeable tips for probing a variety of test points

• Replaceable probe tip socket

• Hands free probing with FreeHand probe holder

Features and Accessories

3 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.

PROBE HEAD

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

Ground
socket

AUTOCOLOR ID

Input socket

AutoColor ID LED

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 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.

DESCRIPTION OF STANDARD AND OPTIONAL ACCESSORIES

The following Tip and Clip accessories can be pushed
into the probe tip socket, ground socket or any other
socketed lead or adapter.

A. Tips

HFP1500-OM-E Rev E 3–1

HFP1500 High Frequency Probe

Straight Tip

The straight tip is rugged and designed for general
probing. Fits in either probe socket.

PACC-PT001, package of 4.

Sharp Tip

Rugged, titanium tip designed to connect to the small­est vias and small test points. Fits in either probe
socket.

PACC-PT002, package of 4.

IC Lead Tip

Covered in insulation on all sides (except for a small
edge), this tip was designed to prevent shorting neigh­boring IC leads. The gold part of the tip is not insulated
and should touch the IC lead to be tested. It is one-size­fits-all and will work with any IC lead pitch. Fits in either
probe socket.

PACC-PT003, package of 4.

SMD Discrete Tip

The crescent shape of this tip is designed to fit tightly on
capacitors, resistors, transistors and other surface
mount components with discrete leads. Fits in either
probe socket.

PACC-PT004, package of 4.

3–2 HFP1500-OM-E Rev E

Bent Sharp Tip

B. Clips

Micro Clip (0.5 mm)

Features and Accessories

Made out of titanium, this tip is ideal for situations that
require the user to hold the probe parallel to the circuit
board under test. Also gives the user more control when
holding the probe like a pencil. Fits in either probe
socket.

PACC-PT005, package of 4.

A pincher like tip designed to hold onto fine pitch leads
and small components, commonly found in SMD ICs.
Fits in either probe socket, or can be used with a lead.

The Micro Clip is an optional accessory for the
HFP1500

PACC-CL001, package of 4.

Clip (0.8 mm)

A pincher like tip designed to hold onto larger wires and
components than possible with the Micro Clip, including
through-hole mounted components.

This clip cannot be connected directly into either of the
probe head sockets; it must be connected to a lead.

PK006-4, package of 2.

Ground Spring with Hook

A flexible spring connected to a square pin that fits into
either of the probe head sockets. Designed to be used
as a ground lead, there is a hook on the end of the
spring so that it can probe general circuits.

PACC-LD001, package of 4.

HFP1500-OM-E Rev E 3–3

HFP1500 High Frequency Probe

Square Pin Ground Spring

A flexible spring connected to a square pin that fits into
either of the probe sockets. Designed to be attached to
a square pin on the circuit under test.

PACC-LD002, package of 4.

Offset Pin

The offset pin is designed to be attached to either
socket of the probe head. The offset pin is the highest
quality grounding solution and is recommended in high
frequency applications.

405400003, package of 1.

C. Leads

While longer leads provide greater flexibility when connecting the probe to a circuit, the added
inductance may degrade the fidelity of high frequency signals. See Section 4 for additional infor­mation.

3–4 HFP1500-OM-E Rev E

Short and Long Right Angle Lead

Short and Long Single Lead

D. Probe Holder

Features and Accessories

This lead has a socket on one end and a bent square
pin on the other to connect to the input or ground socket
of the probe body, and may be used for general pur­pose probing.

PACC-LD003 (short), PACC-LD004 (long), packages
of 4.

This lead can be used for either ground or input lead.

It has a socket on one end and a square pin on the
other and may be used for general purpose probing.

PACC-LD005 (short), PACC-LD006 (long), packages
of 4.

FreeHand Probe Holder

FreeHand lets you focus on the oscilloscope screen

instead of on maintaining contact to multiple test points.
It allows the user to concentrate on what is really impor­tant – the waveform.

It is designed to keep most of the weight on the probe
tip and will prevent lost contact when a bump to the
table shakes the circuit under test.

Additionally, the HFP probe can be mounted horizon­tally or vertically in the FreeHand, giving added mea-
surement flexibility.
