INTRODUCTION

The

HP

10400A

Miniature

Passive

Probe

family

offers

modular

construction

and

improved

reliability.

Modular

construction

allows

individual

replacement

of

probe

tips,

cables,

and

chassis

assemblies

which

reduce

probe

replacement

and

repair

costs.

Improved

cable

and

strain

relief

design

Increase

reliability.

Hewlett-Packard

miniature

probes

significantly

reduce

the

problem

of

probing

densely

populated

IC

(integrated

circuit)

components

or

the

characteristically

minute

conductors

on

IC

boards.

These

small,

lightweight

probes

allow

measurements

that

were

previously

very

difficult,

while

reducing

the

hazard

of

shorting.

The

probe

body

fits

in

the

hand

as

comfortably

as

a

pencil.

Two

accessories

that

further

simplify

and

improve

connection

to

dual

in-line

packages

are

the

IC

grabber

(included

accessory)

and

the

IC

Test

Clip

(HP

Model

10024A,

available

accessory).

DESCRIPTION

The

HP

10400A

Miniature

Passive

Probe

family

consists

of

fourteen

probes

and

includes:

two

1:1

probes

for

high

impedance

inputs,

eight

10:1

probes,

one

100:1

probe

for

low

capacitance

loading

and

large

signals,

and

three

probes

for

oscilloscopes

with

50

ohm

inputs.

HP

10431A

and

HP

10441A

include

a

probe

sensor

on

the

chassis

assembly

that

enables

HP

54111D

and

HP

54112D

Digitizing

Oscilloscopes

to

read

the

probe

attenuation

factor.

ACCESSORIES

SUPPLIED

The

following

accessories

are

supplied

with

each

probe

of

the

HP

10400A

family:

General

Purpose

Grabber.

One

general

purpose

grabber

is

supplied

with

each

probe

model.

The

general

purpose

grabber

is

attached

to

the

probe

tip

for

use

on

1C

pins

and

other

typical

circuit

measurements.

HP

Part

Number

5061-6160,

Integrated

Circuit

Grabber.

One

integrated

circuit

(IC)

grabber

is

supplied

with

each

probe

model.

The

IC

grabber

is

attached

to

the

probe

tip

to

allow

easy

and

firm

grip

to

an

IC

without

the

hazard

of

shorting

adjacent

pins

on

the

IC.

HP

Part

Number

5061-6161.

Ground

Lead.

One

ground

lead

with

alligator

clip

is

supplied

with

each

probe

model.

The

ground

lead

has

a

ferrite

bead

included

in

its

construction

which

reduces

noise

In

the

measured

signal.

HP

Part

Number

5061-6162.

Barrel

Insulator.

One

barrel

insulator

is

supplied

installed

on

the

tip

of

each

probe

model.

The

barrel

insulator

prevents

possible

shorting

of

probe

tip

and

circuitry.

Use

barrel

Insulator

with

the

general

purpose

grabber

for

correct

fit

of

grabber.

Accessory

Package.

One

accessory

package

is

supplied

with

each

passive

probe.

The

accessory

package

contains:

four

grounding

spanners,

one

barrel

insulator,

eight

colored

cable

markers,

and

one

adjustment

screwdriver.

ACCESSORIES

AVAILABLE

The

following

accessories

may

be

ordered

for

use

with

the

HP

10400A

Miniature

Passive

Probes:

HP

Model

10024A.

IC

clip

provides

easy

probing

and

good

high-frequency

grounding

of

dual

in-line

packages

and

includes

four

insulated

circuit

interface

pins.

Additional

circuit

interface

pins

are

available

in

packages

of

twelve

pins.

Each

pin

has

a

tip

on

the

end

so

that

probes

such

as

those

on

HP

logic

analyzers

may

be

connected

for

fast,

functional

checks

of

circuit

operation.
