3-1. INTRODUCTION

The

procedures

in

this section test

the

HP

16515A/16A

1

GHz

Timing Analyser's electrical per-

formance

using

the

specifications listed

in

Section

I

as

the

performance standards.

All

tests

can

be

performed without access to

the

interior of

the

in-

strument.

At

the

end

of this section

is

a

form

that

can

be

used

as

a record of performance test

results.

3-2. RECOMMENDED TEST

EQUIPMENT

Equipment recommended for performance tests

is

listed

in

table

1-2.

Any equipment that

satisfies

the

critical specifications

given

in

the table

may

be

sub-

stituted for

the

recommended

models.

3-3. TEST RECORD

Results

of performance

tests

may

be

tabulated

on

.

the

Performance

Test

Record

(table

3-1)

at

the

end

of

the

procedures.

The

test record lists

all

of

the

tested

specifications

and

their acceptable limits.

The

results

recorded

on

the test record

may

be

used

for comparison

in

periodic

maintenance

and

troubleshooting or after

repairs

have

been

made.

3-4. PERFORMANCE TEST INTERVAL

Periodic performance verification of

the

HP

16515A/16A

1

GHz

Timing

Analyzer

is

required

at

two

year

intervals.

The

instrument's performance

should

be

verified after it

has

been

serviced,

or if

improper operation

is

suspected. Further

checks

requiring access to

the

interior of

the

instrument

are

included

in

the adjustment section,

but

are

not

required

for

the

performance verification.

SECTION III

PERFORMANCE TESTS

3-5. PERFORMANCE TEST

PROCEDURES

All

performance tests should

be

performed

at

the

instruments environmental operating temperature

and

after

a 15-minute warm

up

period.

3-6. TEST CONNECTOR

The

performance tests

and

troubleshooting proce-

dures

require

connecting

pulse

generator outputs

to probe assembly inputs. Figure

3-1

is

a test con-

nector that may

be

built to allow testing of multiple

channels

(up

to eight at

one

time).

The

test con-

nector consists of a

BNC

connector

and

two

lengths

of

wire.

Connecting more than eight

chan-

nels

to

the

test connector

at

a time will induce load-

ing

of

the

circuit

and

true

signal

representation

will

degrade.

Test

results

may

not

be

accurate if

more

than

eight

channels

are

connected to the test con-

nector.

The

Hewlett-Packard part number for

the

BNC

con-

nector

in

figure

3-1

is

1250-1032.

An

equivalent

part

may

be

used

in

place of

the

Hewlett-Packard

part.
