DESCRIPTION

9H-1-4.

When

plugged

measure

frequency,

frequency

ratio,

period,

period

average,

time

interval,

and

time

A

single-channel

or

a

two-channel

totalize

function

is

provided.

The

two-channel

function

totalizes

pulses

on

Channel

during

pulses

on

Chan-

nel

and

for

signal

is

provided

for

the

four

functions

of

frequency,

frequency

ratio,

average

measurements.

INSTRUMENT

IDENTIFICATION

9H-1-9.

Hewlett-Packard

uses

a

two-section,

nine-

digit

serial

number

(0000A00000)

mounted

on

the

rear

panel

to

identify

the

instrument.

The

first

four

digits

are

the

serial

prefix

and

the

last five

digits

refer

to

the

specific

instrument.

If

the

serial

prefix

on

your

instrument

differs

from

that

listed

on

the

title

page

of

this

section,

there

are

differences

between

the

manual

and

your

instrument.

Lower

serial

prefixes

are

General

Information

9H-1-10.

The

printed

circuit

board

within

the

instru-

ment

is

identified

by

a

two-section,

10-digit

part

number

(e.g.,

05308-60001)

and

a

four-digit

series

number

(e.g.,

“SERIES

1440A”).

The

series

number

identifies

the

electrical

characteristics

of

the

com-

plete

printed-circuit

assembly.

A

replacement

circuit-

board

assembly

may

have

a

different

series

number

than

the

assembly

originally

supplied

with

the

instru-

ment.

Therefore,

when

troubleshooting

a

circuit-

board

assembly,

ensure

that

the

series

number

on

the

schematic

diagram

matches

the

series

number

on

the

board

assembly.

If

the

series

number

on

the

assembly

is

lower

than

the

number

on

the

schematic

diagram

in

Subsection

VIII,

refer

to

Subsection

VII

of

this

docu-

ment

for

change

information.

If

the

series

number

on

the

assembly

is

higher

than

the

number

on

the

sche-

9H-1-2

matic

diagram

in

Subsection

VIII,

the

change

infor-

mation

is

provided

If

the
